Abstract:
Abstract The objective was to evaluate the effects on paper properties when replacing a minor share of wood fibre by synthetic fibre. The aim was to increase tear strength and stretch while minimizing the loss of tensile strength in paper consisting of mechanical pulp. Tested synthetic fibres included PLA and viscose fibres mixed with mechanical or chemi-mechanical pulp. Even at relatively low proportions, the synthetic fibres contributed to a significant increase of tear strength in the wood fibre based papers. With the highest tested proportion (20%) the increase of tear index in PGW based stock was 243% with PLA and 177% with viscose fibre. However, a simultaneous decrease in tensile strength and tensile stiffness was observed. The stretch at break remained unchanged. Thickness reduction of the synthetic fibres resulted in an increase of tear strength. The effect is due to the high fibre length of synthetic fibres, producing mechanically well entangled networks, coupled with the high enough strength of the synthetic fibres.

Abstract:
The design of flexible sensors which can be incorporated in textile structures is of decisive importance for the future development of wearables. In addition to their technical functionality, the materials chosen to construct the sensor should be nontoxic, affordable, and compatible with future recycling. Conductive fibres were produced by incorporation of carbon black into regenerated cellulose fibres. By incorporation of 23 wt.% and 27 wt.% carbon black, the surface resistance of the fibres reduced from 1.3 × 1010 Ω·cm for standard viscose fibres to 2.7 × 103 and 475 Ω·cm, respectively. Fibre tenacity reduced to 30–50% of a standard viscose; however, it was sufficient to allow processing of the material in standard textile operations. A fibre blend of the conductive viscose fibres with polyester fibres was used to produce a needle-punched nonwoven material with piezo-electric properties, which was used as a pressure sensor in the very low pressure range of 400–1000 Pa. The durability of the sensor was demonstrated in repetitive load/relaxation cycles. As a regenerated cellulose fibre, the carbon-black-incorporated cellulose fibre is compatible with standard textile processing operations and, thus, will be of high interest as a functional element in future wearables.

Abstract:
The lubrication of dry viscose fibres by a two component finish, and the lubrication of wet Iyocell fabric against metal, with various aqueous lubricant systems, has been studied. Secondary ion mass spectrometry (SIMS) was investigated as a means of providing direct chemical information from finished fibre surfaces. The composition and distribution of a two component finish applied to viscose fibres was determined successfully. When applying finish from a bath, the surface composition of the finished fibres was not controlled by the bath conditions. Increasing the concentration of finish in the bath did, however, increase the total amount of finish deposited, and increasing the concentration of antistat relative to lubricant in the bath increased the amount of antistat relative to lubricant deposited on the finished fibres. Fibre friction was determined using the capstan method. The friction forces, measured for finished viscose fibres, were correlated with the finish application conditions. Increasing the emulsion concentration in the finish bath reduced fibre/metal friction, but finish component ratio, emulsion concentration, dip time and bath temperature did not affect fibre/fibre friction. Spray applying the finish resulted in unfinished regions on the fibre surfaces and the electrical resistance of fibre bundles was not reduced. Bath application of finish did lower electrical resistance in comparison with unfinished fibre, but none of the bath deposition variables had a significant effect on electrical resistance.

Abstract:
Les fibres et les filaments textiles sont soumis lors de leur transformation en filés et en fils à des sollicitations très sévères. Le niveau de sévérité des sollicitations s'élève lors de la transformation des textiles linéaires en textiles surfaciques surtout lors du tissage. Dans cette opération, les structures sont soumises à des extensions répétées de fréquences élevées avec une élongation élevée. Ce phénomène provoque des casses nuisibles au bon fonctionnement du processus et une modification de la structure du matériau en cours d'élaboration, voir une déstructuration de celui-ci. Ce phénomène a été analysé au moyen d'un dynamomètre rapide soumettant les textiles linéaires à des F- compris entre 0,01 et 220s-1. Une méthodologie d'essai a été définie et le comportement de matériaux filamentaires tels que le polyester et le polyamide modélisé en fonction du titre du fil, du nombre de filaments et de la torsion. Des modèles de type pseudoplastiques et logarithmiques permettent une bonne approche du comportement des fils étudiés. Les modèles analogiques ne sont pas satisfaisants, mais en revanche, un modèle de Eyring à amortisseur hyperbolique donne une bonne approche. A partir de ces résultats, le comportement de deux matériaux synthétiques a été étudié, ainsi qu'un matériau artificiel viscose. Celui-ci se présente sous deux formes, filaments et filés de fibres de mêmes titres, mais de torsions différentes, de type Ring-Can. Ces fils et filés ont été soumis à des. F- compris entre 0,01 et 220s-1 et différentes lois de comportement ont été proposées. Une analyse des faciès de rupture au MEB à permis de mettre en évidence le mode de rupture et la vitesse de sollicitation limite à partir de laquelle le matériau passe du ductile au fragile. Cette étude a permis d'une part de corréler le comportement du fil avec les casses se produisant pendant le processus de fabrication et d'autre part de déterminer les caractéristiques de la forme de rupture du matériau.

Abstract:
Des composites polyamide-6 renforcés fibres de verre obtenus par injection réactive ont été caractérisés afin de remplacer ces fibres synthétiques par des fibres biosourcées de viscose haute ténacité. La première étape a été l’étude physico-chimique des fibres et de la matrice polymère thermoplastique par des techniques multiples : DSC, ATG, essais mécaniques, FTIR, RMN et mesure d’angle de contact. Afin d’améliorer l’interface entre la viscose haute ténacité et le polyamide-6, les fibres de viscose ont été fonctionnalisées en deux étapes. Premièrement, un traitement plasma oxygène a permis le nettoyage de la surface de ces fibres. Elles ont été ensuite fonctionnalisées par un agent de couplage silane. Une nouvelle méthode de dépôt de microgouttes de polymère sur les fibres a été développée, dans des conditions représentatives de l’injection réactive, afin de vérifier l’avantage d’un traitement de surface des fibres. Cette approche permet de déterminer la résistance au cisaillement interfacial entre les fibres et le polyamide-6, par déchaussement des microgouttes. Par la suite, des composites polyamide-6 renforcé viscose traitée ou non traitée ont été obtenus
Polyamide-6 / glass fibers composites were studied in order to replace glass fibers with high tenacity viscose as a reinforcement, using a reactive injection process. The first step was the physico-chemical characterization of fibers and matrix using different techniques such as: DSC, TGA, mechanical testing, FTIR, NMR and contact angle measurements. In order to improve the interface between high tenacity viscose and polyamide-6, the viscose fibers were functionalized using a two step method. First, oxygen plasma was applied as a cleaning process to remove impurities. Secondly, the fibers were functionalized using an aminosilane. A new deposition technique of polymer microdroplets onto fibers, in conditions similar to these of reactive injection process, was developed in order to confirm the advantages of the silane treatment. Moreover, a pull-out test of these microdroplets led to the determination of the interfacial shear strength between polyamide-6 and high tenacity viscose fibers. Then, polyamide-6 composites reinforced with high tenacity viscose were obtained

Abstract:
Au cours de ces travaux, les propriétés thermophysiques du toron de viscose ainsi que leurs évolutions pendant la carbonisation ont été étudiées. Des analyses thermiques ATG et DSC ont ainsi permis d’identifier la capacité thermique apparente du toron et les sources de chaleur liées aux transformations du précurseur. Le rapprochement de l’analyse ATG, mesures du retrait et de l’évolution du diamètre des fibres ont ensuite permis de déterminer l’évolution de la masse linéique et de la masse volumique du toron. Les propriétés radiatives du toron de viscose ont également été mesurées à différents stade de carbonisation. Un dispositif de mesure de conductivité thermique longitudinale effective de toron à été développé, réalisé et utilisé pour caractériser l’évolution de la conductivité thermique du toron au cours de la carbonisation. Un modèle numérique par éléments finis du procédé de carbonisation à été réalisé, en utilisant les propriétés précédemment mesurées et les mesures de vitesse de l’écoulement d’azote dans le four et du profil de température à la paroi réalisées sur le four de carbonisation de laboratoire. Ce modèle a été validé avec des mesures de températures réalisées au cœur du toron au cours de la carbonisation. Les transferts de chaleur lors de la carbonisation de fibres de précurseurs ont finalement été étudiés à l’aide du modèle numérique développé
During this work, the thermophysical properties of the viscose strand as well as their evolution during carbonization have been studied. ATG and DSC thermal analyzes have made it possible to identify the apparent thermal capacity of the strand and the heat sources linked to transformations of the precursor. The comparison of the ATG analysis, measurements of the shrinkage and the evolution of the diameter of the fibers then made it possible to determine the evolution of the linear density and the density of the strand. The radiative properties of the viscose strand were also measured at different stages of carbonization. A device for measuring the effective longitudinal thermal conductivity of the strand has been developed, built and used to characterize the evolution of the thermal conductivity of the strand during carbonization. A finite element numerical model of the carbonization process has been developed, using the previously measured properties and the measurements carried out on the laboratory furnace: the velocity profile of the nitrogen flow in the furnace as well as the wall temperature profile. This model has been validated with temperature measurements made at the core of the strand during carbonization. Heat transfers during the carbonization of precursor fibers have been finally studied using the developed numerical model

Abstract:
Les interactions fluide-structure sont d'un grand intérêt en ingénierie et pour des applications industrielles et médicales. Comprendre les interactions entre des particules aux formes complexes et des écoulements peut mener à de nouveaux projets pour l'administration ciblée de médicaments, pour des micro capteurs de débit et à une meilleure compréhension du comportement des micro-organismes. Dans cette thèse, nous étudions l'interaction fluide-structure de particules chirales de taille microscopique à bas nombres de Reynolds. Les particules sont rigides et confinées dans une géométrie 2D ou flexibles avec une forme hélicoïdale. Combiner des techniques de microfabrication, comme des méthodes d'assemblage multi-échelles et la microfluidique, permet d'avoir un excellent contrôle à la fois sur les propriétés géométriques et mécaniques des fibres et aussi sur les caractéristiques de l'écoulement comme ses propriétés Newtoniennes et non Newtoniennes, sa vitesse et sa géométrie. Dans un premier temps, nous avons étudié des fibres rigides, 2D et asymétriques, i.e. des fibres en L. Les confinements latéral et transversal ont été étudiés tout comme la forme de la fibre. Lorsque la particule est transportée dans un écoulement visqueux, elle tourne jusqu'à atteindre une orientation d'équilibre. Dans cette orientation particulière, la fibre se décale vers les murs latéraux du canal. Une étude complète des trajectoires de la fibre a été réalisée et des comparaisons avec des particules symétriques ont été faites. Ce sujet de recherche pourrait aider à concevoir des dispositifs pour trier des particules à des fins médicales. Dans un second temps, nous avons étudié des fibres hélicoïdales flexibles de taille micrométrique. La dynamique de formation de l'hélice a été analysée. Les hélices se forment à partir de rubans droits 2D qui, de façon spontanée, s'enroulent quand ils sont libérés dans l'eau. La forme hélicoïdale est obtenue seulement quelques minutes après la libération des rubans mais l'hélice continue à rétrécir pendant plusieurs heures jusqu'à ce qu'elle atteigne une courbure préférentielle. Deux temps caractéristiques sont identifiés dans cette dynamique de formation. Un modèle a été développé pour comprendre le complexe équilibre entre les forces élastiques, de tension de surface et visqueuses aux temps courts. Après avoir analysé plusieurs hypothèses, comme l'impact d'une couche sacrificielle, une possible modification du module du matériau et la présence de fluage, l'évolution du rayon de l'hélice aux temps longs s'explique probablement par du fluage. La dynamique d'extension et de relaxation de la fibre flexible a aussi été étudiée dans des fluides Newtonien et non Newtonien. L'étude dans des solutions de polymères est pertinente et intéressante car la taille des micro hélices est comparable à celle des flagelles des micro-organismes et à celle de chaînes de polymères de grande masse moléculaire. Il s'agit donc d'un problème mutli-échelles complexe car la viscosité locale au niveau du ruban pourrait être différente de la viscosité globale de l'écoulement
Fluid-structure interactions are of wide interest in engineering, industrial and medical applications. Understanding the interactions between complex shaped particles and flows might lead to new designs for targeted delivery, microflow sensors and to a better understanding of the behavior of microorganisms. In this thesis, we study the fluid-structure interaction of microscale chiral particles at low Reynolds numbers. The particles are rigid and confined in a 2D geometry or flexible with a helical shape. The combination of microfabrication techniques, such as multiscale assembly methods and microfluidics, enables to have a perfect control on both the geometrical and mechanical properties of the fibers and the flow features such as Newtonian or non Newtonian properties, the flow velocity and the flow geometry. First we studied asymmetric 2D rigid fibers, i.e. L-shaped fibers. Both lateral and transversal confinements have been investigated, as well as the shape of the fiber. When the particle is transported in viscous flows, it rotates until reaching an equilibrium orientation. In this specific orientation, the fiber drifts towards the lateral walls of the channel. A full investigation on the trajectories of the fiber has been performed and comparisons with symmetric particles have been done. Such research may help design devices to sort particles for medical purposes. Secondly we studied flexible microscale helical fibers. The dynamics of the helix formation has been investigated. The helices are formed from straight 2D ribbons, which spontaneously coil when released in water. The helical shape is reached only several minutes after the release but the helix keeps shrinking during several hours until reaching a preferred curvature. Two different timescales are identified in this formation dynamics. A model has been developed to understand the complex balance between elastic, surface tension and viscous forces at short times. After investigating several assumptions such as the impact of a sacrificial layer, a possible change in the modulus of the material and a creep behavior, the evolution of the radius at long times is most likely explained by creep. The extension and relaxation dynamics of the flexible fiber has also been studied in Newtonian and non Newtonian fluids. The study in polymer solutions is relevant and interesting because the size of the microhelix is comparable to the flagella of microorganisms and to the chains of high molecular weight polymers. Complex multiscale problems are then involved as the local viscosity at the scale of the ribbon might differ from the global viscosity at the scale of the flow

Abstract:
Naturskyddsföreningen gav författarna uppgiften att undersöka förekommande viskosprocesser och alternativa regenereringsprocesser, detta för att identifiera hur hållbara de är ur ett miljöperspektiv och vilka processer som går att applicera på bambu. Detta för att se möjligheten att märka bambuviskos med Bra Miljöval och för att klargöra frekvent uppkommande frågor angående bambuviskos. Syftet är att se på de olika processernas kemiska innehåll samt vilka utsläpp de orsakar till luft och vatten. Ett delmål med rapporten är att den ska kunna användas som material vid vidareutveckling av kriterierna för Bra Miljöval Textil. Resultat som erhållits vid jämförelser av studerad litteratur är att de betydande faktorerna för miljöpåverkan från massaframställningen samt viskos- och lyocellprocessen beror av: använda kemikalier i processen, energianvändningen och vilken typ av energi, möjligheten till rening av utsläpp till luft och vatten samt återvinning av energi och kemikalier. Beroende på vilket råmaterial som används vid massaframställningen kan skillnader i markanvändning, användning av bekämpningsmedel och gödningsmedel samt upptagande av koldioxid skilja sig. Massa- och fiberframställning bör vara integrerade då energiförbrukning och mängd kemikalier kan minskas. Energin kan dessutom återvinnas till större utsträckning.Genom miljömärkningar från oberoende organisationer blir det lättare för konsumenter att göra miljömedvetna val och veta vad märkningarna står för. Sammanfattningsvis ska det påpekas att om regenererad bambu framställs som den görs idag är den ingen hållbar fiber, men sker framställningen i en integrerad process där kemikalier och energi återvinns samt rening av utsläpp till luft och vatten sker, kan bambuviskos bli en hållbar fiber för framtiden. The Swedish Society for Nature Conservation (SSNC) gave the authors the task to investigative present viscose processes and alternative regeneration processes to identify how sustainable they are from an environmental perspective, and examine which processes that can be applied to bamboo. This to see the possibility to label bamboo viscose with “Bra Miljöval” (Good Environmental Choice), which is the eco-label of SSNC, and to clarify the frequently emerging issues concerning bamboo viscose. The aim is to look at the various processes, their chemical content and the emissions they cause to air and water. Another objective of the report is that it can be used as material for further development of the criteria for “Bra Miljöval”.Results obtained when comparing the studied literature is that the significant factors of the environmental impact from the pulp production, the viscose and lyocell processes depends on: chemicals used in the process, energy and energy source, the possibility of purifying emissions to air and water and recycling of energy and chemicals. Depending on the raw materials used for pulp production, differences in land use, use of pesticides and fertilizers as well as absorption of carbon dioxide differ. Pulp and fibre production should be integrated to reduce energy consumption and the amount of chemicals used. The energy can also be recycled to a greater extent.Eco-labels from independent organizations will make it easier for consumers to make environmentally conscious choices and be aware of what the labels stand for.In conclusion, it should be noted that if the regenerated bamboo is produced as it is today, it is not a sustainable fibre. If the production is done through an integrated process in which chemicals and energy recovery and purification of air and water occurs, bamboo viscose can be a sustainable fibre for the future.

Abstract:
A preocupação mundial em relação aos impactos ambientais e seus reflexos positivos ou negativos na natureza têm mobilizado diversos setores da indústria. O processo de fabricação da viscose quando não controlado é altamente poluidor, causando impactos ao meio ambiente. Portanto, a escolha da sua matéria-prima pode amenizar esses problemas. O objetivo deste trabalho é analisar comparativamente os tecidos de malha fabricados com fibras de viscose convencional eucalipto e outras - com fibras de viscose obtidas a partir do bambu. Para a análise foram escolhidas as seguintes matérias-primas: fios 100% viscose convencional (fiação de anéis e jato de ar) e fios 100% viscose de bambu (fiação de anéis) e fabricadas malhas com gramaturas médias estatisticamente iguais. Os tecidos foram beneficiados e realizados os ensaios de gramatura, tendência à formação de pilling e resistência à solidez à água. Os resultados experimentais mostraram que não existem diferenças significativas entre as características estudadas.
The global concern regarding the environmental impacts has assembled several industry sectors. This study has as a goal to analyze relatively two types of mesh fabrics: viscose, which can be produced through cellulose regeneration obtained by bamboo or from other trees or plants, and thus, it can be chosen one or the other within a sustainable development context. This manufacturing process of viscose is highly pollutant, provoking negative impacts to the environment. Therefore, the choice of raw material might reduce these issues relating to sustainability. This comparison also has an objective to open a space for discussions regarding to sustainability concept in textile sector, which many studies are limited to analyze the results comparing materials only, not considering the process as a whole, from the choice of raw material, obtention, cultivation, transformation, to the final product, including the lifecycle, the durability and disposal of a fashion product. The experimental results showed that no significant differences between the characteristics studied.

Abstract:
The paper presents the implementation of a model based predictive control algorithm of an industrial drying process for Viscose staple fibres. A short review of the earlier published modelling procedure presents the linearised multi-input multi-output (MIMO) state space formulation of the design model. The design of the predictive control scheme incorporates constraints on the manipulated variables, set-points for the manipulated variables, and active disturbance rejection for the main disturbance variables of the drying process. Some simulation results demonstrate the beneficial effects of this structure, and the choice of proper weightings is also briefly discussed. Implementation issues and various measured results are presented. The problem of redundant but biased measurements of fibre humidity is addressed and the superior performance of the new concept compared to the existing PID-control is demonstrated. Both energy consumption and variation of humidity in the final product are significantly reduced by the successful implementation.

Abstract:
In this study, the permeability of ordered fibrous media towards normal and parallel flow is determined analytically. In this approach, porous material is represented by a “unit cell” which is assumed to be repeated throughout the media. Several fiber arrangements including: touching and non-touching arrays are considered. Modeling 1D touching fibers as a combination of Channel-like conduits, a compact relationship is proposed to predict permeability. Employing an integral technique and assuming a parabolic velocity profile within the unit cells, analytical relationships are developed for pressure drop for rectangular arrangements. The developed models are successfully compared with existing experimental data collected by others for square arrangement over a wide range of porosity. Due to the random nature of the porous micro structures, determination of exact permeability of real fibrous media is impossible. However, the analyses developed for ordered unit cells enable one to predict the trends observed in experimental data. Moreover, it is shown that the proposed normal flow permeability of square unit cell serves as a lower bound for the permeability of fibrous media. The effects of unit cell aspect ratio and fibers diameter on the permeability are also investigated. It is noted that with an increase in the aspect ratio the normal permeability decreases while, the parallel permeability remains constant. It is also shown that the permeability of fibrous media is related to the diameter of fibers squared.

Abstract:
In injection moulding, long glass fibre reinforced thermoplastics (LGFT) are an attractive way to produce large parts at low cost. The strength of the part depends chiefly on the average fibre length, fibres which are subjected to considerable attrition during processing in conventional three stage screws. First of all, in this study we have coupled a melting analysis in a conventional screw to a model of fibre breakage whereby a fibre anchored at one end in the solid bed is submitted, at its other end, to the intense shear stress of the molten polymer flowing in the film close to the barrel. As the melting of the solid bed progresses, more fibres are unlayered and submitted to bending which intensity is depending on both the fibre length and orientation. When the bending is too high, the fibre breaks. Bimodal fibre length distribution are obtained and compared to existing data. The sensibility of the model to main processing parameters such as screw rotation, initial fibre length, viscosity, barrel temperature and screw geometry are also investigated. Next, we present a new analytical solution for flow of a viscous fluid in a single screw channel that takes into account the torsion and curvature of the channel. Contrary to common knowledge in polymer processing based on the Parallel Plate Model, we found that, in the case of cross-sections with large aspect ratio, torsion effects can be significant. The implication of the model on velocity field, residence time and mixing efficiency is investigated and compared to the predictions of the classical Parallel Plate Model, to finite elements calculations, and to 3D experimental measurements. Indeed, an innovating device has been developed in our laboratory to visualize the flow of a viscous fluid in the channel of a screw. It consists of a transparent barrel and of a rotating screw, pumping a transparent viscous fluid at room temperature. A particle plunged in the flow is constantly monitored by four video-cameras placed around the barrel and recording its position in a frame. The 3D path lines are then computed.

Abstract:
This paper presents a numerical approach for calculating the single fiber motion in a viscous flow. This approach addresses such issues as the role of axis ratio and fiber shape on the dynamics of a single fiber, which was not addressed in Jeffery’s original work. We develop a Finite Element Method (FEM) for modeling the dynamics of a single rigid fiber suspended in a moving fluid. Low Reynolds number viscous flows are considered since these best represent the flow conditions for a polymer melt within a mold cavity. Our approach seeks the fiber angular velocities that zero the hydrodynamic torques acting on the fiber using the Newton-Raphson method. Fiber motion is then computed with a Runge-Kutta method to update the position, i.e. the angle of the fiber as a function of time. This method is quite general and allows for fiber shapes that include, but are not limited to, ellipsoidal fibers (such as that studied in Jeffery’s original work), cylindrical fibers and beads-chain fibers. The relationships between equivalent axis ratios and geometrical axis ratios for cylindrical and beads-chain fibers are derived in this paper.

Abstract:
The multiscale structure of spider silk is widely studied because of its superior mechanical properties. Its high tenacity allows the absorption of the kinetic energy of fast and large preys. The mechanism of sacrificial bonds enhances the stretchability and toughness of spider capture-silk. With this in mind, we fabricate microstructured fibers with sacrificial bonds using the dragged viscous thread instability. A thread of viscous liquid flowing towards a perpendicular moving platform buckles repetitively and creates different periodical patterns. A solution of 25% polylactid acid (PLA) dissolved in the dichloromethane (DCM) is extruded from a 30μm diameter needle onto a moving platform. By decreasing the speed ratio between the thread extrusion speed and the platform moving speed, we obtain different instability patterns: catenary, meandering, alternating (loop falling on alternate sides of the main thread), and coiling (all the loops falling on the same side). The spatial frequency of the periodical patterns linearly increases with the speed ratio until overlapping occurs. When the thread loops on itself, it welds and fuses with itself to form a bond which solidifies as the solvent evaporates and the thread dries. Different fiber patterns are tested in an electromechanical tensile machine and their performance are compared to a straight fiber. Sacrificial bonds require significant energy to break (i.e., ranging between 0 to 110% of the yield value of a straight fiber). Finally by controlling the instability parameters, we are able to tailor the mechanical properties of the resulting fibers such as its breaking strain, rigidity and toughness which could lead to different protective wear applications.

Abstract:
This paper presents a computational approach for simulating the motion of nano-fibers during polymer nano-composites processing. A finite element-based Brownian dynamics simulation is proposed to solve the motion of nano-fibers suspended within a viscous fluid. In this paper, a Langevin approach is used to account for both hydrodynamic and Brownian effects. We develop a stand-alone Finite Element Method (FEM) for modeling the hydrodynamic effect exerted from the surrounding fluid. The Brownian effects are regarded as the random thermal disturbing forces/torques, which are modeled as a Gaussian process. Our approach seeks solutions using an iterative Newton-Raphson method for the fiber’s linear and angular velocities such that the net forces and torques, i.e. the combination of hydrodynamic and Brownian effects, acting on the fiber are zero. In the Newton-Raphson method, the analytical Jacobian matrix is derived from our finite element model. Fiber motion is then computed with a Runge-Kutta method to update the fiber positions and orientations as a function of time. Instead of re-meshing the fluid domain as fiber moves, we applied the transformed essential boundary conditions on the boundary of fluid domain, so the tedious process of updating stiffness matrix of finite element model is avoided. Since Brownian disturbance from the fluid molecules is a stochastic process, Monte-Carlo simulation is used to evaluate the motion of a great many fibers associated with different random Brownian forces and torques. The final fiber motion is obtained by averaging a numerous fiber motion paths. Examples of fiber motions with various Péclet numbers are presented in this paper. The proposed computational methodology will be used to gain insight on how to control fiber orientations in micro- and nano-polymer composite suspensions in order to obtain the best engineered products.

Abstract:
An emerging approach to repair and replace a great number of the ligament and tendon injuries that occur each year is the use of tissue engineering principles to fabricate replacement tissues. One of the current challenges in tendon/ligament tissue engineering is fabricating scaffolds that possess both the proper mechanical and biological properties. A promising strategy to produce such scaffolds is electrospinning. Electrospinning uses a high-voltage power supply to draw viscous polymer solutions into ultra-fine fibers with nanometer-scale diameters, thus structurally mimicking native extracellular matrix components, such as collagen fibrils. Nano-scale fibers have been previously shown to enhance cellular proliferation, as well as stimulate cells to maintain morphology and phenotype when compared to scaffolds composed of larger fibers [1]. Furthermore, electrospinning provides researchers the flexibility of fabricating aligned scaffolds with isotropic mechanical properties to mimic native tissue mechanics [2]. However, scaffolds composed of aligned electrospun nanofibers often do not possess the elasticity and tensile strength required to properly carry out the mechanical function of tendon/ligament tissues. One approach that has been used to enhance mechanical properties of fibrous scaffolds is to weave multiple fibrous bundles into a braided scaffold. [3]. In this study, we fabricated a novel tendon/ligament tissue engineering scaffold that combines enhanced biological properties of electrospun scaffolds with enhanced mechanical properties through braiding. Furthermore, our approach offers the versatility to tailor tensile strength and elasticity of the braided scaffolds simply by varying the pattern of braiding, making it possible for researchers to construct tendon/ligament scaffolds with various mechanical properties.

Abstract:
In this paper both a coarse and fine wood fibre type of Lost Circulation Material (LCM) is tested in the laboratory. It is shown how these fibre treatments work. The fibre type is partially oil wetting making them suitable for application in oil based drilling fluids. The fine material helps stopping small drilling induced fractures, while the coarse helps stopping lost circulation into several natural fractures or coal or conglomerate formations. In the article, the selection of wood fibres is described in more detail. Testing of the fine materials were conducted conventionally by pumping drilling fluid volumes with LCM onto slotted disks in fluid loss apparatuses. The coarse fibres are too large to be tested in these apparatuses. Therefore, gravel with grain diameter around two centimetres was filled into transparent cylinders. The pore throats created by these gravel particles were above half a centimetre. For both of these LCMs the experiments show the sensitivity of the LCM concentration in the drilling fluid to stop the lost circulation. Also, it is shown the effect of the LCM on viscous properties of the drilling fluids. Not all LCMs can be pumped through the bit. The article describes the need for circulation subs in the bottom hole assembly (BHA) to hinder the LCM blocking the entire BHA.

Abstract:
Abstract Fiber glass rod (i.e. FGR) is an uniaxial fiber reinforced plastic. In the movement of the rods, some dynamic characteristics such as the wave velocity and the damped coefficient are most important dynamic factors in analysis of the dynamic response of the rods. Generally, FGR are composed of two materials, fibers and resins. The particularities of the parameters for the wave velocity, etc of FGR are mainly depend on these two materials of different properties. This paper studies longitudinal velocity for FGR theoretecally and measure it by vibration method. The viscous damped coefficient is also measured by the theory of viscoelasticity. This paper presents that the viscous damped characteristic of material is mainly depend on the coupling mass between the rods.

Abstract:
Recently, the observation technology of micro structure has made great progress, and then collagen fiber orientation of meniscus can be measured accurately. This makes it possible to evaluate the stress in knee joint by considering the collagen fiber orientations at the micro scale. In this study, we developed visco-isotropic/anisotropic hyperelastic constitutive equations (Iso-VHE/Aniso-VHE) for menisci, which can reflect the initial collagen fiber orientations and their deformation induced rotations. Subsequently, we constructed a finite element (FE) model of normal human knee joint by using the magnetic resonance (MR) tomography images. The FE analysis with the proposed constitutive equations and FE model clarifies the reinforcement effect of collagen fibers on mechanical characteristics of knee joint. Our computational prediction clarified that the stress concentration occurred on the contact parts of articular cartilages of femur and tibia, which met the tendency of the experimental results. Furthermore, the maximum compressive stresses evaluated by Aniso-VHE always showed a lower value as compared with Iso-VHE. This suggested that the anisotropy of meniscal collagen fibers relieved the stress concentration and lowered the maximum value. Therefore, our proposed FE analysis was proved to have a potential to reveal the functions of meniscus and knee joint.
