Abstract:
The paper gives a set of basic relations characterizing the phenomena of viscous polymer resin flow through fiber reinforcement and the resin curing process. We describe the technological process of manufacturing composite structures. The influence of the resin curing process on values of residual stresses in composite constructions is analyzed taking into account two components: thermal shrinkage and chemical shrinkage of resins. For cases of 2-D structures, the method of formulating such tasks has been demonstrated. The types of design variables appearing in the optimization problems in this area are also presented. The 2-D optimization problems have been formulated. Various optimization problems are solved in order to demonstrate the influence of discussed relations on values of residual stresses and curing processes of thermosetting resins.

Abstract:
Fluorescent inkjet ink was composed of solvent, resin, phosphor, assistant agent etc, solvent and resin were the main components in the fluorescent inkjet ink, which had an important effect on the luminescent property and various physical properties. In order to research and develop the fluorescent inkjet ink, formulation principle had been used to design the ingredient, and fluorescent inkjet ink samples had been prepared. The effect of different solvents and resins and mixed solvent and resin on the significant performance of the fluorescent inkjet ink had been studied, such as the viscosity, surface tension, luminous intensity, and fluorescence quantum yield. The results indicated that through the formulation design principle, formulation could be optimized to make the ink have high fluorescence intensity and physicochemical properties which could meet practical printing requirement.

Abstract:
Purpose: We have previously reported that the Australian Northern Kaanju (Kuuku I’yu) medicinal plant Dodonaea polyandra has anti-inflammatory activity. This is attributed largely to the presence of clerodane diterpenoids contained within the leaf resin. We envisaged developing a topical preparation to treat indications relating to skin inflammation. However, it was unknown whether the resin could be incorporated into a suitable dosage form while retaining the therapeutic value demonstrated in previous work. Therefore, the following study was undertaken to assess parameters of safety and efficacy for a prototype formulation containing the leaf resin extracted from D. polyandra. Methods: Using the assessment criteria of optimum appearance, tactile feeling, spreadability and odour, 78 different formulations were developed. Formulation stability was assessed using a centrifugal test with preparations displaying phase separation further modified or re-formulated. A prototype formulation containing 5% w/w plant resin was selected and subjected to in vitro release studies. This was quantified through HPLC analysis using two major bioactive diterpenoids as reference. The prototype formulation was tested for efficacy in a TPA-induced acute murine skin inflammation model as well as a 3D human skin model for irritancy/toxicity (Epiderm™). Results: The prototype resin cream was a chartreuse-coloured homogenous semisolid preparation that was readily spreadable upon contact with skin with no sensation of tackiness, residual greasiness, or irritation. The optimized cream showed no phase separation after 30 min centrifugation at 825 g. In the TPA-induced inflammation model, the resin formulation significantly reduced ear thickness and interleukin-1 beta levels in mouse ear tissue. The 5% w/w resin cream formulation showed no irritancy in a 3D human skin model. Conclusions: Our results demonstrate that bioactive resin from D. polyandra can be formulated into a stable and non-irritant semi-solid dosage form and reduce parameters of acute skin inflammation in vivo.

Abstract:
In a recent paper on the revised formulation of Spurr low viscosity embedding medium with ERL 4221 the importance of maintaining an appropriate anhydride:epoxide (A:E) ratio was discussed. By understanding a few simple concepts about epoxy resin formulations and setting up a formulation table it is possible to create new resin mixtures with good sectioning properties and other desirable properties such as decreased viscosity and increased beam stability.Before starting a formulation you need to know the molecular weight of the anhydride and the WPE (weight per epoxide equivalent) of the epoxy resin component. The molecular weights and WPEs are usually printed on the bottle or can be obtained from the vendor. An A:E ratio of 0.7:1.0 -1.0:1.0 is used for most biological specimens. Increasing the A:E ratio results in a harder block; decreasing the A:E ratio results in a softer block. Table 1 shows a basic formulation spreadsheet where the molecular weights of the anhydrides and the WPEs of the epoxy resin components can be entered. The A:E ratio is entered under the anhydride for the molar ratio and the molar ratios of the epoxy components are entered under the epoxy components. The calculations are done as shown in each column and row.

Abstract:
The aim of this study was to prepare fast disintegrating combination tablet of taste masked Levocetrizine dihydrochloride and Montelukast sodium by using direct compression method. To prevent bitter taste and unacceptable odour of the Levocetrizine dihydrochloride drug, the drug was taste masked with ion exchange resins like Kyron-T-104 and Tulsion-412. Among the two resins, Kyron-T-104 was selected for further studies because of high drug loading capacity, low cost, and better drug release profile. An ion exchange resin complex was prepared by the batch technique and various parameters; namely, resin activation, drug: resin ratio, pH, temperature, and stirring time, and swelling time were optimized to successfully formulate the tasteless drug resin complex (DRC). The tablets were prepared using microcrystalline cellulose (MCC) PH 102 as diluent along with crospovidone (CP), croscarmellose sodium (CCM), and sodium starch glycolate (SSG) as a superdisintegrants. The tablets were evaluated for weight variation, hardness, friability, wetting time, water absorption ratio, disintegration time (DT), and dissolution study and it was concluded that the tablet formulation prepared with 2% SSG + CCS showed better disintegration time in comparison with other formulation and good drug release. The stability studies were carried out for the optimized batch for three months and it showed acceptable results.

Hexamethoxymethyl melamine (HMMM) was used to modify UF resins to obtain good performance with low formaldehyde emission. The effect of urea to formaldehyde ratio, HMMM content on the properties of UF resin was studied in detail. The results suggested that urea to formaldehyde ratio to be 1:0.9 and 20% HMMM content is the optimum formulation to afford desired UF resin. The viscosity, solidification time, bond strength and formaldehyde emission of the modified UF resins were also studied. The results revealed that the performance of the modified UF achieved the chinese standard.

Abstract:
A study of fertilizer formulation (organic + inorganic) to increase the formation of sapwood (gubal) on agarwood plants (Gyrinops versteegii), had done to find the best fertilizer formulation that capable of increase and accelerate either growth and agarwood formation of sapwood on agarwood trees. The first year of study was conducted in Marga Tabanan Village. The field research was Randomized Block Designed (3 groups) with single factor of treatment. The tested treatment were 6 formulation of compound fertilizers and a control (unfertilized treatment). The compound fertlizers consisted of urea, SP-36, KCl, local compost, and dolomite in varying doses. The fertilizer formulations were applied on 21 agarwood trees that previously inoculated with mixed inoculant of Fusarium solani and Rhisopus sp. Three months after inoculation, the data from the following parameters were measured and statistically analyzed: plant height, stem circumference, sapwood weight, resin content and soil chemical properties.The results showed that the tested fertilizer compound had significant effect on plant height, sapwood weight, and resin rendement. No significant effect of fertilizer compound measured on the stem circumference. The highest sapwood weights was obtained on C treatment (14.39 g). The highest resin yield was obtained on B treatment (3.91%) which was relatively the same as that on C treatment (3.85%). Thus, the best fertilizer formulation for either plant growth, agarwood formation or agarwood resin was C treatment (100 g urea + 100 g SP-36 + 100 g KCl) + (7.5 kg compost) + (75 g Dolomite) per tree.

Abstract:
The formulation of a brake pad requires the optimization of multiple performance criteria. To achieve a stable and adequate friction (µ), the brake pad materials should have low fade and higher recovery characteristics coupled with less wear and noise. Among the properties mentioned, resistance to fade is very difficult to achieve. The type and amount of resin in the friction material is very critical for structural integrity of the composites. The binder should not deteriorate under any diverse conditions. The thermal stability of friction materials and its capacity to bind its ingredients collectively under diverse conditions depend upon the quality and proportion of resin. The current work evaluates the fade and recovery behaviour of developed friction composites from two different resins which are traditional straight phenolic resin and the alkyl benzene modified phenolic resin. Two brake pads with these different resins were fabricated as per Industrial Standard. TGA is carried between 150 – 4000 C as this zone of temperature is very critical which accounts for the weight loss (Thermal degradation). Friction and wear studies were carried out on a friction coefficient test rig as per SAE J661a standard. The results showed that the fade and wear of the friction materials were closely related to the thermal decomposition of the binder resin and durability of the contact plateaus, which were produced by the compaction of wear debris around hard ingredients on the rubbing surface. It was clearly observed that the friction materials with modified resin showed significant reduction in fade %. Friction materials made with higher thermal stability showed resistance to fade. However wear didn’t show much noticeable changes.

Abstract:
Abstract Traditionally, it has been believed that there is an incompatibility between the chlorinated rubber surface and polychloroprene adhesives resulting in a lack of adhesion. However, in this study it has been shown that a polychloroprene adhesive (PCP30P) produces similar T-peel strength values when using a polyurethane (PU) adhesive in joints produced between a chlorinated thermoplastic SBS rubber and roughened leather. In both cases a cohesive failure mode within the rubber was obtained. This polychloroprene adhesive (PCP30P) contains a thermoreactive phenolic resin in its formulation. The nature of the resin greatly influences the viscoelastic properties of the polychloroprene adhesive. Thus, polychloroprene adhesive with no resin or with resins of a different nature do not produce suitable adhesive joints between the chlorinated rubber and the leather (Terpene phenolic resin (PCP30TP), a glycerol esther colofony resin (PCP30EC) and an aromatic hydrocarbon resin (PCP30AH) were studied). The interactions produced between the chlorinating agent and the adhesive were studied by ATR-IR on solid films of the polychloroprene adhesives and the tackifier resins previously immersed in the chlorinating solution (0.5 and 3 wt% TCI/MEK). All the polychloroprene adhesives were modified by the chlorinating agent, being capable of producing a good interaction with the chlorinated rubber surface at the interface. Therefore, the good performance of the PCP30P adhesive compared with the other polychloroprene adhesives has been ascribed to rheological behavior more similar to the PU adhesive assessed by DMTA. The PCP30P adhesive is the most elastic material among all the considered polychloroprene adhesives. This increased elasticity and better viscoelastic properties are imparted by the thermoreactive phenolic resin in its formulation.

Abstract:
The high functionality epoxy resins tetraglycidyl-4,4’-diaminodiphenyl-methane(TGDDM) and triglycidyl-p-aminophenol (TGPAP) are the main components in most aerospace grade epoxy resin formulations. Owing to their high reactivity and high viscosity, TGDDM and TGPAP pose difficulties when used in wet layup composite manufacturing. As such, these resins are often modified to achieve the desired performance both in the liquid and cured states. The main objective of this thesis is to optimise a low viscosity multi-component epoxy resin formulation suitable for use as an aerospace grade composite matrix. The formulation will allow for the addition of high levels of thermoplastic to improve the fracture toughness of the resin whilst also maintaining resin processability. Through the use of thermal analytical techniques this thesis aims to study the effects of varying the TGDDM/TGPAP ratio, incorporation of a low viscosity bi-functional epoxy resin, the diglycidyl ether of bisphenol F (DGEBF) and changes to the stoichiometric ratio (r)between reactive groups of the epoxy resin and amine hardener (4,4’-diaminodiphenylsulphone, DDS) in multi-component epoxy resin formulations. Resin formulations were optimised using factorial experimental design (FED). Results from two FED’s showed curing multi-component resins at a low stoichiometric ratio significantly increased the processing window whilst also increasing the glass transition temperature (Tg) of the cured resin. No apparent benefit could be assigned to the inclusion of TGDDM owing to its poor processability and a Tg similar to TGPAP. Up to 60% DGEBF was incorporated in a multi-component resin formulation whilst still attaining a Tg greater than 220°C. Its inclusion at 60% had the additional benefit of increasing the processing window by 48 minutes over TGPAP, an increase of 62%. Two optimised resin formulations, 100% TGPAP (100T) and a binary mix of 60% DGEBF and 40% TGPAP (60D) were taken forward to study the effects of adding a thermoplastic toughener (polyethersulphone, PES) in incremental amounts up to 50wt%. SEM images showed all toughened 100T resins had a phase separated morphology whilst all 60D resins were homogenous. The phase separation seen in 100T did not improve the matrix fracture toughness when loaded at 10 wt% and 30 wt% PES. Only when 50 wt% PES was added did fracture toughness increase in comparison to the homogenous 60D resins. Through factorial experimental design two epoxy resin formulations which excluded TGDDM were optimised with a low stoichiometric ratio. The optimum aerospace formulation is dependent on the desired processability and fracture toughness of the resin. High DGEBF-containing formulations give the longest processing windows whilst the 100% TGPAP formulation toughened with 50% PES has the highest fracture toughness.

Abstract:
The main objective of this research is to address the relationship between formulation of friction lining materials and their propensity to friction induced noise generation. The basic idea was formulated earlier by Dr. Filip, who showed that the friction layer plays the relevant role when noise is observed during braking. It was shown that when newly formed patches (parts of the friction layer) exhibit a large difference in the coefficient of friction, brake lining is stretched and released repeatedly, which leads to significant vibrations and corresponding noise when coupled with the vibration mode of the system. Farhang ,on the other hand, demonstrated that noise can be related to specific surface roughness parameters and when properties of friction lining and friction layer (such as compressibility, stiffness and modulus of elasticity) fit into certain specific value ranges, noisy behavior occurs. This research will address the braking related to friction induced noise in relation to the properties of the bulk lining material and the character and properties of the friction layer. The friction tests will be performed using the CAFS-developed (Szary and Lee) real time noise measurement system compatible with the major part of SAEJ2521 standard (note that the system does not allow for reliable measurement of frequencies lower than 900 Hz). The mechanical properties of fourteen samples will be investigated. Of the fourteen samples, friction layer of three of the samples will be investigated by several analytical techniques developed by Dr. Filip [1]. They include polarized light microscopy, scanning and transmission electron microscopy equipped with energy dispersive microanalysis, and X-ray diffraction. This research summarizes data from the J2521 dynamometer test of the Dodge Caravan samples exhibiting specific compressibility, porosity and hardness. Also, this research provides the results of friction surface analysis by SEM with energy dispersive microanalysis, light microscopy, surface roughness, and X ray diffraction. Of the fourteen samples, Bendix has the largest occurrence of noisy braking. Based on techniques developed by Dr. Filip, the characteristics of the friction layer strongly influence brake noise propensity. The friction layer characteristics are dependent on brake formulation. As predicted, "noisy stop" and "quiet stop" samples exhibit completely different friction surfaces.

Abstract:
The interpretation and modelling of the dielectric response of thermosetting materials during cure was the main focus of this study. The equivalence of complex permittivity and complex impedance in terms of information content was outlined in a series of case studies covering the separate effects of dipolar movements and charge migration as well as the combined effect of the two polarisation mechanisms. Equivalent electrical circuits were used in order to model the evolution of the complex impedance during cure. A numerical method that can model consecutive spectra throughout the cure was developed. The method is based on Genetic Algorithms and requires only input from the modelling of the initial spectra. Complex impedance spectra were collected during the cure of a commercial epoxy resin formulation under isothermal and dynamic heating conditions. The spectra were analysed and modelled. The modelling was successful over the whole frequency range of the measurements (1 Hz – 1 MHz). The analysis of the estimated model parameters showed that charge migration dominates the dielectric response in a wide frequency range. In addition, the modelling algorithm also distinguished between the effects of electrode polarisation and dipolar movements in the signal. A new equivalent circuit was used in order to map the frequency regions where the each one of the three phenomena that together comprise the dielectric signal can be monitored most effectively. A chemical cure kinetics model was developed for the studied system. A correlation between the maximum point of the imaginary impedance spectrum and the reaction conversion was established. A mathematical model, based on a simple linear dependence of the dielectric signal on conversion and temperature, was built. The model predictions agreed well with the experimental data. The aim of simplifying the interpretation of the dielectric signals led to the development of a new experimental technique. Temperature Modulated Dielectric Analysis employs temperature modulations superimposed on an underlying thermal profile in order to separate the influence on the signal of the temperature alone from that of the cure reaction. The early study carried out here shows that such measurements are feasible and reveals important issues for its further development.

Abstract:
Dans ce manuscrit, un modèle complet pour la simulation de l'écoulement d'un fluide thermor éactif à travers un milieu poreux fortement compressible est présenté. Ce modèle est utilisé pour l'étude des procédés d'élaboration des matériaux composites par infusion à travers leur épaisseur (Liquid Resin Infusion-LRI et Resin Film Infusion-RFI ). Dans ces procédés, le mélange entre les renforts et la résine liquide est réalisé dans la direction transverse aux plans des préformes pendant la phase de mise en forme. Les coˆuts sont ainsi réduits et les problèmes de remplissage éliminés. Ces procédés sont néanmoins peu maîtrisés et les caractéristiques de la pièce finale difficilement prévisibles (principalement les épaisseurs et les porosités). La mise au point d'un modèle numérique constituerait un bon outil pour développer et finaliser de nouvelles solutions composites. D'un point de vue physique, l'infusion de la résine à travers l'épaisseur des préformes est une conséquence de la pression appliquée sur l'empilement résine/préforme. Dans cette analyse multi-physique deux types de problèmes sont rencontrés. Tout d'abord, on connait mal les conditions de couplage entre les zones liquides, gouvernées par les équations de Stokes, et les préformes imprégnées assimilées à des milieux poreux, gouvernées par une loi de Darcy et une loi de comportement mécanique non-linéaire. Par ailleurs, les interactions entre l'écoulement de la résine et la compression des préformes ne sont pas bien maîtrisées. Le modèle développé inclut donc une condition de Beaver-Joseph- Schaffman modifiée pour le couplage entre les zones de Darcy et de Stokes. Une formulation ALE pour l'écoulement de la résine dans un milieu poreux déformable subissant de fortes déformations est utilisée et couplée à une formulation Lagrangienne Réactualisée pour la partie solide. Ces deux mécanismes physiques sont couplés à des modèles thermo-chimiques pour traiter la réticulation de la résine sous l'action du cycle de température. Dans ce travail, un certain nombre d'outils numériques et de nouvelles formulations ont été développés en vue de simuler les procédés LRI et RFI. Chaque outil est étudié et validé analytiquement ou numériquement avant d'être intégré dans les modèles LRI /RFI. Des simulations numériques d'infusion sont ensuite présentées et commentées, puis une première comparaison avec des essais expérimentaux est proposée.

Abstract:
This dissertation focuses on developing 3D printing as a fabrication method for microfluidic devices. Specifically, I concentrate on the 3D printing approach known as Digital Light Processing stereolithography (DLP-SLA) in which serially projected images are used to sequentially photopolymerize layers to build a microfluidic device. The motivation for this work is to explore a much faster alternative to cleanroom-based microfabrication that additionally offers the opportunity to densely integrate microfluidic elements in compact 3D layouts for dramatic device volume reduction. In the course of my research, an optical approach was used to guide custom resin formulation to help create the interconnected hollow regions that form a microfluidic device. This was based on a new a mathematical model to calculate the optical dose delivered throughout a 3D printed part, which also explains the effect of voids. The model was verified by a series of 3D printed chips fabricated with a commercial 3D printer and a custom resin. Channels as small as 108 µm x 60 µm were repeatably fabricated. Next, highly compact active fluidic components, including valves, pumps, and multiplexers, were fabricated with the same 3D printer and resin. The valves achieved a 10x size reduction compared with previous results, and were the smallest 3D printed valves at the time. Moreover, by adding thermal initiator to thermally cure devices after 3D printing, the durability of 3D printed valves was improved and up to 1 million actuations were demonstrated.To further decrease the 3D printed feature size, I built a custom 3D printer with a 385 nm LED light source and a 7.56 µm pixel pitch in the plane of the projected image. A custom resin was also developed to take advantage of the new 3D printer's features, which necessitated developing a UV absorber screening process which I applied to 20 candidate absorbers. In addition, a new mathematical model was developed to use only the absorber's molar absorptivity measurement to predict the resin optical penetration depth, which is important for determining the z-resolution that can be achieved with a given resin. The final resin formulation uses 2-nitrophenyl phenyl sulfide (NPS) as the UV absorber. With this resin, along with a new channel narrowing technique, I successfully created flow channel cross sections as small as 18 µm x 20 µm.With the custom 3D printer, smaller valves and pumps become possible, which led to the invention of a new method of creating large numbers of high density chip-to-chip microfluidic interconnects based on either simple integrated microgaskets (SIMs) or controlled-compression integrated microgaskets (CCIMs). Since these structures are directly 3D printed as part of a device, they require no additional materials or fabrication steps. As a demonstration of the efficacy of this approach, 121 chip-to-chip interconnects in an 11 x 11 array for both SIMs and CCIMs with an areal density of 53 interconnects per square mm were demonstrated, and tested up to 50 psi without leaking. Finally, these interconnects were used in the development of 3D printed chips with valves having 30x smaller volume than the valves we previously demonstrated. These valves served as a building block for demonstrating the miniaturization potential of an active fluid mixer using our 3D printing tools, materials, and methods. The mixer provided a set of selectable mixing ratios, and was designed in 2 configurations, a linear dilution mixer-pump (LDMP) and a parallelized dilution mixer-pump (PDMP), which occupy volumes of only 1.5 cubic mm and 2.6 cubic mm, respectively.

Abstract:
Les travaux présentés dans ce manuscrit sont consacrés à l’étude et à l’élaboration de résines de collage bio-sourcées pour remplacer les résines Urée-Formol (UF) d’origine pétrochimique, sources de formaldéhyde, utilisées actuellement dans l’industrie panneautière. Les résines étudiées dans le cadre de cette thèse sont formulées à partir de ressources locales (dextrines issues d’amidon de maïs et tanins d’écorces de pin maritime) et doivent respecter certaines contraintes industrielles. Pour répondre à ces contraintes, les travaux de recherche présentés dans ce mémoire vont de la compréhension structurale des mélanges des produits de base jusqu’à la fabrication de panneaux à l’échelle du laboratoire, en passant par la formulation et la réticulation des différentes résines thermodurcissables. Ces travaux montrent qu’il est nécessaire de travailler en milieu alcalin pour solubiliser les tanins. Dans cette situation, les mélanges tanins/dextrines donnent des suspensions colloïdales. Les fractions massiques en tanins et en dextrines permettant d’obtenir des paramètres respectant le cahier des charges varient de 0 à 40%. La réticulation de ces mélanges par l’épichlorhydrine a permis l’obtention de colles thermodurcissables insolubles dans l’eau ayant une bonne stabilité dimensionnelle à sec, mais un pouvoir gonflant plus ou moins important selon la formulation. Les propriétés adhésives, mécaniques et thermiques de ces matériaux ont été caractérisées et ont permis de sélectionner des formulations de colles ayant les meilleures performances thermomécaniques. Enfin, tout en respectant un protocole industriel, des composites ont été fabriqués à partir de ces colles et des particules de bois. Il a été montré que les panneaux de particules obtenus ont des performances mécaniques équivalentes à ceux fabriqués avec des colles UF
This work aims to substitute resins based on formaldehyde as UF by “green” thermosetting adhesives based on natural and renewable local products, in the wood composite industry. The resins studied in this thesis are made from local resources (dextrins from corn starch and tannins from maritime pine barks) and must respect certain industrial requirements. To meet these industrial constraints, the research work of this manuscript deals with studies ranging from the structural understanding of basic product mixtures, up to the characterization of the properties of panels manufactured in the lab, including the formulation and reticulation of resins. These studies show that it is necessary to work in an alkaline medium to solubilize the tannins. In this situation, the tannins / dextrin mixtures give colloidal suspensions. The mass fractions in tannins and dextrins allowing to obtain parameters respecting the specifications vary from 0 to 40%. The epichlorohydrin has been used as hardener to cross-link these resins. Thermosetting materials with good dimensional stability have been obtained. However the resin swelling depends on the composition of the formulation. Adhesive, mechanical and thermal properties of these materials were characterized. Thus, adhesive formulations with the best thermomechanical performances have been selected. Finally, composites have been made from these adhesives and wood particles, respecting an industrial procedure. It has been shown that these panels and those obtained with UF adhesives have equivalent mechanical performances

Abstract:
Les solvants occupent une place prépondérante dans l’industrie chimique et se retrouvent au cœur de nombreuses applications telles que la formulation de produits phytosanitaires, d’encres ou de peintures, le nettoyage industriel ou les procédés d’extraction, de synthèse ou de séparation. L’épuisement des ressources pétrolières, le durcissement de la réglementation, et une prise de conscience collective motivent le développement d’alternatives à l’utilisation de solvants pétrochimiques. En effet, environ 45% des émissions de composés organiques volatils (COVs) en France proviennent de l’utilisation des solvants, qui, pour la plupart, présentent une empreinte environnementale et sanitaire peu favorable. Le panorama des solvants industriels amorce inévitablement une mutation, qui nécessite la recherche de solvants plus respectueux de l’environnement et des utilisateurs, au regard de leurs propriétés et de leur mode de production. Outre les liquides ioniques, les fluides supercritiques et les solvants fluorés qualifiés de solvants verts, les biosolvants sont apparus comme une solution alternative capable de répondre à un grand nombre de spécifications requises dans diverses applications. L’élaboration de biosolvants s’accompagne d’un changement de matière première, au profit de ressources renouvelables issues de la biomasse. Parmi les molécules plateforme biosourcées utilisées pour la synthèse de bioproduits, le furfural, obtenu par déshydratation des sucres contenus dans les rafles de maïs, a été sélectionné dans le cadre de cette étude visant à développer de nouveaux biosolvants, en collaboration avec la société Rhodia-Solvay (projet InBioSynSolv). Ainsi, afin de substituer des solvants conventionnels utilisés pour formuler des actifs phytosanitaires ou pour le nettoyage industriel, deux méthodologies, différentes de l’approche essais et erreurs, ont été étudiées. La première méthodologie, prédictive, se base sur la prédiction des propriétés avant la synthèse des molécules. La formulation inverse est, quant à elle, une méthodologie innovante qui permet de concevoir des molécules de biosolvants grâce à un laboratoire virtuel; les étapes de génération de structures moléculaires et de prédiction des propriétés, sont intégrées à un outil informatique d’aide au design moléculaire (CAMD) qui propose des solutions répondant aux spécifications visées. Dans un premier temps, ces méthodologies ont conduit à identifier un pool de molécules candidates dérivées du furfural et susceptibles de jouer le rôle de solvant pour les applications envisagées. Dans un deuxième temps, la faisabilité des filières de leur production a été étudiée, depuis la molécule plateforme jusqu’à l’utilisation du biosolvant au sein d’une formulation. Pour cela, les molécules candidates ont été obtenues selon différentes voies de synthèse, que l’on a caractérisées à l’aide de la détermination d’indicateurs verts. Une démarche d’éco conception a également contribué à la mise en place d’une approche multi critère intégrant les aspects techniques, environnementaux et socio- économiques. Enfin, la production d’échantillons a permis de vérifier expérimentalement les propriétés recherchées, et de valider l’intérêt des méthodologies de substitution de solvants utilisées, en termes de gain de temps et d’efficacité. Celles-ci pourront être généralisées au développement de différents bioproduits pour accompagner les évolutions des marchés auxquelles doit faire face l’industrie chimique.

Full text
Abstract:
As a lower cost raw material, few demand for equipments, convenient solidification process, cement solidification for radioactive waste is widely used for several decades. Formulations of solidification are complex and diverse, involving various types of substrate and additives. Traditional approach for formulation design is single-factor test whose representation is inadequate and workload is huge. Uniform design based on the theory of Quasi-Monte-Carlo takes advantage of limited and representative tests instead of the system. In the multi-factor formulation design, it can be very quick and convenient to find the formulations required by uniform design table and direct-vision method. This article introduced the application of uniform design table for formulation in cement solidification of nuclear waste resin.

Full text
Abstract:
In the last decade, the evolution in the exploration and transportation of oil and gas as well as efforts to delay the effect of corrosion on strategic and valuable assets like pipelines, have triggered the development of new Fusion Bonded Epoxy (FBE) anticorrosion coatings. A major component in a FBE formulation are solid epoxy resins, which when properly formulated enable the FBE coating to reach higher performance requirements to cope with the ever more challenging conditions in the field. This paper describes how solid epoxy resins (SER) can help high glass transition temperature FBE coatings to protect pipelines operating at high service temperatures from corrosion. A second area of innovation is a solid epoxy resin that helps FBE to cure at lower application temperatures than standard FBE coatings while maintaining the similar corrosion performance. Damage tolerance is the third area of innovation. Dow Coating Materials has developed an epoxy/copolymer resin system which helps the FBE formulator overcome the brittleness of FBE Abrasion Resistance Overcoat (ARO) at subzero temperatures.

Full text
Abstract:
In this study, the mechanical properties of nanoclay reinforced polymeric resins are investigated at various temperatures. In recent years there has been heightened interest to develop nanoclay reinforced composites due to their superior performance compared to neat resins at high temperatures under various loading conditions, including impact. First, polypropylene (PP) resin specimens reinforced with varying weight fractions of nanoclay (0%, 1%, 3%, 6% and 10%) some instrumented with strain gages, were subjected to tensile loads and the stress-strain curves were obtained to determine the mechanical properties of the nanocomposite. Extensive experimental data were obtained. The results indicate that as the weight percentage of nanoclay increases, the strength and stiffness of the resulting nanocomposites also increase. Most of PP specimens exhibited significant deformation (more than 100%) and did not break. High temperatures have a deleterious effect on the strength and stiffness of nanoclay reinforced PP specimens. However, the addition of nanoclay, somewhat mitigates the deterioration of these properties. At lower temperatures the material stiffens, has higher strength and becomes more brittle as failure occurs at much lower strains. Also the tests using different PP resins indicate that the type of resin used has significant effect on the properties of the nanocomposite. A micromechanics model based on the Mori-Tanaka formulation was used to predict the results obtained experimentally. The comparison of theoretical/numerical and experimental results indicates that the Mori-Tanaka formulation may be a useful tool in predicting these properties.

Full text
Abstract:
The trend in new electronic packages is to deliver smaller, thinner space-sensitive packages that meet or exceed customer package reliability expectations. This poses new material challenges in terms manufacturability and reliability. Size, space and manufacturability constrain typical packaging material choices available to meet the desired package performance. This often results in non optimal package performance and some times results in severe reliability challenges. Instead of compromising reliability expectations, the proposed approach engineers new materials to meet or exceed the desired packaging performance while meeting manufacturability criteria. In this paper, nano-particles are used as filler particles for polymer resins to modify the composite material properties. However, instead of a trial and error approach, a predictive simulation based approach is used to achieve the desired results. Advanced nonlinear finite element methodology first determines the desired material properties necessary to meet package reliability requirements. Then, achievable material property variations for a system of polymer resins and nano-particles are predicted. The optimal match is determined between achievable properties and those that will maximize package reliability. A new material was formulated using the predicted polymer resin nano-particle combination. Formulation addressed additional manufacturability issues of uniform dispersion, particle surface chemistry and a manufacturing necessity of photo definition capability. Mechanical properties were characterized to validate the property prediction capability. This validated simulation based approach is very effective in determining the ideal formulation resulting in the desired achievable properties and package reliability.

Full text
Abstract:
The infiltration process is one of the techniques employed to work out polymer matrix composites (PMC) or metal matrix composites (MMC) and with continuous reinforcement. It consists in injecting the liquid (resin or metal) through a fibrous reinforcement placed in a mould. In the case of the MMC, the fibres and the mould are initially preheated at temperatures lower than the temperature of metal solidification. These thermal conditions induce phenomena of phase change of metal when the metal is in contact with the fibres. These phenomena disturb the flow of metal through the fibrous network. In order to follow the displacement of metal in the preform and take into account of the phase change, a two-dimensional numerical model based on a finite volume formulation was developed, on a very simple geometry.
