Abstract:
Water absorption behavior and flexural strength properties of carbon fiber reinforced plastics (CFRP) under hot-wet environment were examined. Those of epoxy resin were also examined for reference. Weight gains of CFRP and epoxy resin were measured after immersion in distilled water at temperatures under 90°C. Quasi-static flexural tests of CFRP and epoxy resin were conducted after immersion for 180 days. Weight gains of CFRP and epoxy resin increased with increasing water temperature. After immersion for 180 days at 90°C, weight gain of CFRP became 3.3times higher and that of epoxy resin was 2.3 times higher than that at RT, respectively. When CFRP and epoxy resin were immersed in distilled water at 90°C, weight gains of CFRP and epoxy resin increased and then decreased. Flexural strengths of CFRP and epoxy resin decreased in distilled water at temperatures less than 90°C. Flexural strengths of dried CFRP and epoxy resin after immersion recovered but were lower than that of virgin CFRP and epoxy resin. Debonding of fiber/resin interface and crack initiation in epoxy resin in distilled water resulted in the strength reduction.

Abstract:
The purpose of the study was to evaluate the adhesion between dental core resin and epoxy resin-based fiber post after treatment with non-thermal atmospheric pressure plasma (NTAPP) and compare with conventional methods of epoxy resin-based fiber post treatments. Contact angle was measured on the surface of epoxy resin before and after NTAPP treatment and X-ray photoelectron spectroscopy was used to analyze the surface chemistry. Finally, two shear bond strength tests were carried out; shear bond strength between core resin and epoxy resin for comparison between NTAPP treated and untreated sample, and push-out shear bond strength between core resin and NTAPP treated commercially available epoxy resin-based fiber post for comparison between NTAPP treated samples with conventionally treated samples. Contact angle on the surface of epoxy resin generally decreased with increasing NTAPP treatment time with presence of surface chemical changes. Also, there was significantly higher shear bond strength and push-out shear bond strength between epoxy resin and core resin for NTAPP treated epoxy resin, even to the conventionally treated epoxy resin-based fiber post with hydrofluoric acid or silane. In conclusion, new technology of NTAPP has potential for application on the epoxy resin-based fiber post to improve endodontic restoration success rate.

Abstract Epoxy resin has been widely used in many fields. The improvement of friction and wear property can further expand the application range of epoxy resin. Filling modification can improve the tribological state of epoxy resin and improve the friction and wear property of epoxy resin. This paper summarizes the research of epoxy resin composite material tribology performance at the forefront of progress. The influence of different fillers on the friction and wear properties of epoxy resin composite materials was discussed from the aspects of the single filling of nano-filler, organic materials and inorganic lubricating fillers and the compound filling of inorganic or organic-inorganic fiber-filler. Many researching literature shows. The mechanical properties of epoxy resin composites are strengthened by adding filler to epoxy resin to improve the load bearing capacity of epoxy resin composites during friction. At the same time, add filler to reduce the surface of epoxy resin and the friction pair of duality between the caking property, and in the process of friction is easy to form transfer film, transfer film to isolate the direct contact of the friction surface, composite materials and the dual friction between surfaces into composite materials and transfer film, the friction between improved tribological condition between the friction pair, reduce the friction coefficient and wear rate of epoxy resin composites multiple fillers can improve the wear resistance and reduce the friction coefficient of epoxy resin composites, so that the epoxy resin composites have better tribological properties.

The properties of phenolic-epoxy copolymer were studied in this paper. DSC was used to detect the possibility of copolymerization between phenolic resin and epoxy resin. FT-IR monitored the reactive process of mixed resin in various temperature stages. DMA revealed that the copolymer possessed high moduli and glass transition temperatures. The result showed that phenolic-epoxy copolymer can react in appropriate proportion. It is better for the copolymer system to avoid rich epoxy without curing agent. The properties of the copolymer could be increased when sacrificed some excellent properties of phenolic and epoxy. The copolymer 70% phenolic & 30% epoxy and 60% phenolic & 40% epoxy posses higher service temperature, lower volumetric shrinkage and excellent mechanical properties.

Abstract:
This paper studies the modification of petroleum asphalt with enzymatic hydrolysis lignin (EHL) epoxy resin. EHL epoxy resin was successfully synthesized by EHL, a novel eco-material with high chemical reactivity. Different amounts of EHL epoxy resin were compounded into AH-70 paving asphalt. The effect of EHL epoxy resin on modified asphalt was examined by penetration, soften point, thin film oven test (TFOT), ductilily tests. The results showed that EHL epoxy resin had marked effect on the high-temperatrue property of increasing softening point at the content of 2-9wt% and it had significantly effect on the low-temperature properties and aging resistance with EHL epoxy resin content of 2-9wt% in modified asphalts. TG analysis indicated that EHL epoxy resin had the high mass loss temperature than pure asphalt. Anti-aging property of asphalt was improved by compounding EHL epoxy resin with asphalt.

Full text
Abstract:
In this research water dispersed epoxy varnishes were produced by reacting solid epoxy resin with ethylene diamine (EDA) and maleinized fatty acids of linseed oil. Maleinized fatty acid (MFA) was produced by the maleinization process, in which, fatty acid and maleic anhydride were reacted under nitrogen atmosphere. Maleinization was performed in order to insert hydrophilic groups to the fatty acid chains, which were then inserted to the backbone of the epoxy resin. This was done to give water dispersibility to the hydrophobic epoxy resin. Solid epoxy resin was dissolved in 1,4-dioxane. Ethylene diamine was then added to the solution at 50&deg<br>C, and stirred for 4 hours. Then the temperature was increased to 80oC and kept for 2 hours. Maleinized fatty acids were then introduced, and the reaction was carried out at 90oC for 10 hours. 1,4-dioxane was used for the removal of the water, which forms as the byproduct. Then the driers were added. The carboxylic groups of the maleinized fatty acid were neutralized by morpholine and the product was dispersed in water. The varnish was applied on test panels and left for air-drying for 24 hours and then baked at 140&deg<br>C for 5 hours. The free epoxy content was determined by pyridinium-chloride titration and it was seen that all the epoxy groups reacted. Also, produced fatty acid was characterized by FTIR spectroscopy and maleinized fatty acid was characterized by H-NMR and FTIR spectroscopy. Hardness, bending, impact resistance, gloss, and abrasion resistance tests were carried out on hardened varnish specimens. The samples generally showed good mechanical and physical properties. While the baking time was increased the hardness of product increased. Samples showed superior impact resistance, gloss, and flexibility.

Full text
Abstract:
In view of an increasing number of reports describing epoxy resinthermoplastic blends, it is clearly important to identify the effects of the thermoplastic on the blend properties. In this work difunctional epoxy resin monomer (Epikote 828) cured with diaminodiphenylsulphone (DDS) or dicyandiamide (DICY) are the model systems used. The thermoplastic is a polyethersulphone (PES) with either hydroxyl terminations (Victrex 5003P, ICI) capable of reaction with epoxy monomer or chlorine terminated (Ultrason E2010, BASF) which is incapable of reaction. The glass transition characteristics of the PES materials are very similar but the Ultrason E2010 is of lower average molecular weight and can be expected to contain more chain ends. Epoxy-DDS-PES systems were prepared with 20phr and 30phr of PES. The effects of the PES on crosslinking and isothermal physical ageing behaviour were examined. Enthalpy relaxation data were curve fitted using a Kohlrausch function. Mechanical and dielectric spectroscopy data were analysed using W-L-F and power law methods. Despite a tendency for the PES to reduce the crosslink density of the network, the blends had glass transition temperatures almost identical to the unmodified resin. The reduction in crosslink density improved Glc compared to the unmodified resin but promoted faster physical ageing and more rapid embrittlement when the blends were aged at the same temperature as the neat resin. The epoxy-DICY-PES system was studied at one composition of 30phr PES. The system was two phase but fast curing led to premature arrest of the phase separation process. Annealing at various temperatures from below the glass transition of the low temperature phase to just below the glass transition of the high temperature phase resulted in what is believed to be microscopic morphological changes detectable only barely by DSC and quite clearly from dynamic mechanical analysis. These changes were not manifest in the morphology of fracture surfaces. Annealing was found to decrease G1c.

Abstract:
Highly crosslinked epoxy resin systems are essential in aerospace applications due to the high operating temperatures. Although highly crosslinked epoxy resins have the required glass transition temperature (Tg) for the application, they are inherently brittle and matrix toughness is improved by incorporation of a second phase. Previous studies have focused mostly on toughening of lightly crosslinked epoxy systems, whereas this study investigates toughening of a highly crosslinked epoxy resin system using thermoplastic toughners poly(ether sulfone) (PES) and a poly(methyl methacrylate)-b- poly(butyl acrylate)-b-poly(methyl methacrylate) (MAM) block copolymer (BCP).

Full text
Abstract:
Photopolymerization of epoxy-acrylate hybrid resins takes advantages of inherent properties present in the free-radical and cationic reactions to reduce oxygen inhibition problems that plague free-radical reactions. Similarly, the combined reaction mechanisms reduce moisture sensitivity of the cationic reactions. Despite the advantages of epoxy-acrylate hybrid resins, problems persist that need to be addressed. For example, low conversion and polymerization rate of the epoxides are a problem, because the fast acrylate conversion prevents the epoxide from reaching high conversion. Controlling phase separation is challenging, since two moieties with different properties are reacting. The physical properties of the polymer will be impacted by the availability of different moieties. High shrinkage stress results from the acrylate moiety, causing buckling and cracking in film and coating applications. The overall goal of this study is to use the fundamental knowledge of epoxy-acrylate hybrid resins to formulate industrially viable polymers. In order to achieve this goal, the study focuses on the following objectives: (I) determine the apparent activation energy of the hybrid monomer METHB, (II) increase epoxide conversion and polymerization rate of hybrid formulations, and (III) control physical properties in epoxy-acrylate hybrid resins. In order to increase the epoxide conversion and rate of polymerization, the sensitivity of epoxides to alcohol is used to facilitate the activated monomer (AM) mechanism and induce a covalent bond between the epoxide and acrylate polymers through the hydroxyl group. It is hypothesized that if the AM mechanism is facilitated, epoxide conversion will increase. As a result, the resins can be tailored to control phase separation and physical properties, and shrinkage stress can be reduced. In pursuit of these objectives, the hybrid monomer METHB was polymerized at temperatures ranging from 30°C to 70°C to obtain apparent activation energy of 23.49 kJ/mol for acrylate and 57 kJ/mol for epoxide moeities. Then, hybrid systems pairing hydroxyl-containing acrylates with epoxides were formulated to promote the faster AM mechanism. Monomer composition was changed in the presence of hydroxyl-containing acrylate, and initiators were carefully selected in order to control phase separation. The conversion of acrylate and epoxide was monitored in real time by Raman spectroscopy. The physical and mechanical properties were monitored using dynamic mechanical analysis. Epoxide conversion and rate of polymerization in epoxide-acrylate hybrid monomer systems were shown to increase through the introduction of a hydroxyl group on the meth/acrylate monomer, taking advantage of the faster AM mechanism. In addition, this covalent bond linking the epoxide network to the meth/acrylate polymer chains resulted in little or no phase separation and a reduction of the Tg for the hybrid polymer compared to the neat epoxide. Fundamental knowledge gained from this research will enable the use of epoxy-acrylate hybrid resins in variety of applications. For instance, shrinkage may be reduced in dental fillings, noise and vibration problems in aircraft and other machinery may be controlled, and photopolymerization cost could be reduced in thin film applications.

Abstract:
In this project, hydrophilic bicontinuous microporous materials were synthesized via one‑pot polycondensation, using epoxy compounds and polyamines as the main monomer and curing agents. To achieve this goal, two approaches have been taken. In the first approach, monoliths were prepared by partial aminolysis of polyhydroxybutyrate (PHB) biopolyester by various polyamines under mild condition. The oligomers were then crosslinked by epoxy monomer to form porous rigid polymer structures. A two‑level full factorial screening design was established to investigation how the curing temperature, the amount of PHB, and the monolith loading affected the material morphology. In the second approach, monoliths were obtained by polycondensation of epoxy monomers and polyamines in presence of pore forming sol­vents. The morphology of final products was optimized by changing the polymer precursor compositions, or the pore-forming solvents. The specific surface areas of the materials were characterized by nitrogen cryo‑sorption and scanning electron microscopy was used to evalu­ate the monolith morphologies and skeleton structures. Chemical composition was explored by infrared spectroscopy (FTIR), solid-state nuclear magnetic resonance (NMR), and X-ray photoelectron spectroscopy (XPS). Finally, sample TEPIC100, having desired bicontinuous microporous scaffold, was in situ synthesized in a 1.0 mm i.d. surface-modified PEEK tubing.

Full text
Abstract:
This thesis describes the work carried out at Brunel University to develop novel optical fibre sensors capable of monitoring the cure state of an epoxy/amine resin system. The sensors were of simple construction, consisting of an optical fibre from which the silicone cladding layer had been removed over a short length. This stripped length was embedded into the curing resin system. The sensor was successfully used in two ways: i) as an evanescent absorption sensor to monitor specific absorption bands of the resin system. The absorption of energy from the evanescent wave of the optical fibre by absorbing media allows evanescent absorption spectra to be obtained. Absorption spectra were obtained from sensors embedded in a model curing resin system over narrow wavelength ranges. These wavelength ranges corresponded to positions of known absorptions in the spectra of active components in epoxy/amine systems. By monitoring the change in these absorptions it was possible to obtain information about concentration of the amine hardener functional group throughout cure; ii) as a refractive index sensor capable of monitoring the changes in the refractive index of the resin system during cure. A laser diode was used to launch light into the sensor and the intensity of light emerging from the other end of the fibre was monitored. Changes in the resin system refractive index caused changes in the guiding properties of this the sensor. This resulted in a significant change in the intensity of light recorded by the detector and allowed the cure process to be followed. This sensor was also embedded into a unidirectional pre-preg system and was able to follow the cure of the system. The results from the two sensing methods have been compared with data obtained using FTIR spectroscopy and Abbe refractometry during the resin system cure. A theoretical model of sensor response has been developed and compared with the experimental data obtained. The sensor response has also been compared to predictions made by several models of evanescent sensor systems obtained from the literature. These models have been modified so that they can be applied to a sensor embedded into a curing resin system. An analysis of the correspondence between theory and experiment is presented.

Abstract:
AbstractThe compatibilization of graphene/epoxy resin composites and carbon nanotube CNT/epoxy resin composite were studied based on the crystallized models with the molecular dynamics simulation in this paper. The effect of resin formula on compatibility parameter of carbon matrix was studied, and the combination of diglycidyl ether of bisphenol A (E51) resin with isophorone diamine (IPD) as the hardener achieved the best result. Further, the graphene/epoxy resin composite were constructed to investigate the effect of functional groups on components compatibility, conclude hydroxyl, carboxyl and amino. It was found that the functional groups had strong impact on compatibility parameter of graphene and CNT, whereas carboxylated graphene exhibits the best compatibility with the resin. This is due to the strong electronegativity of the carboxyl group, which induces a molecular interaction with the epoxy groups at the end of E51. The present study is expected to provide significant molecular insight into the relationship of compatibility between carbon matrix and epoxy resin for fuel cell composite bipolar plates.

Abstract:
AbstractThree different classes of thermosetting styrene-free resins were investigated to assess their suitability to constitute the matrix phase in the reformulation of composites reinforced with mechanically recycled glass fibers. Resin reactivity and mechanical properties after curing were compared to commercial styrene-based, unsaturated polyester resins. The polymeric resin, acting as a binder, could be properly selected depending on the desired reactivity, processability, and mechanical behavior. Some prototypal examples of reformulated composites with different types and contents of recycled glass fibers were produced and mechanically tested. The combination of the epoxy resin with up to 60 wt% of mechanically recycled glass fibers resulted in an increase of elastic modulus up to 7.5 GPa.

Full text
Abstract:
Abstract Bis-Phenol A epoxy resin-based coatings are known for excellent corrosion and chemical resistance. Limitations of this class of coatings are poor flexibility, thermal stability and weather resistance. Traditional siloxane resins are commonly used in the industry to improve the thermal and weather resistance of bis-Phenol A epoxy coatings. In addition, organo-functional silicone polymers have been used to provide improved flexibility, but create recoatability issues. Siloxane resins and silicone polymers offer partial solutions to the limitations of bis-Phenol A epoxy coatings, but do not eliminate all of the limitations associated with this system. To fill this gap, a new class of organo-functional siloxane resins was developed by Dow Corning Corporation as epoxy resin crosslinkers providing flexible coatings with excellent recoat performance. Detailed work was done to compare modifications of a bis-phenol A epoxy paint using a variety of silicon-based technologies including aminopropyltrimethoxy silane, aminopropylmethyldiethoxy silane, methoxy-terminated siloxane resin, silanol-terminated siloxane resin, and amine-terminated siloxane resin.

Full text
Abstract:
Abstract An epoxy coating with excellent cathodic disbondment resistance performance is developed in this paper. Bisphenol A epoxy resin, bisphenol F epoxy resin, novolac epoxy resin and C9 petroleum resin were used as the resin system of coating. The orthogonal test of four factors at four levels was applied to select the amount of each resin. The mixed curing agent of polyamide and modified phenolic amine showed good performance. When the ratio of polyamide and modified phenolic amine was 2:1, the anti-cathodic disbonding performance of the coatings was the best. The optimized ratio of pigment to resin (pigment/binder ratio) is 1:1, which was concluded from the correlation between P/B (pigment/binder) ratio (0.75:1~1.5:1) and cathodic disbonding resistance performance. The final epoxy coating formulation with optimized resin, curing agent and pigment/binder ratio has excellent cathodic disbonding performance, which is only 3 mm of cathodic disbonding equivalent diameter after 48 hours cathodic disbondment test (-1.5V (vs. SCE), 65°C seawater).

Abstract:
Abstract Manufacturing processes that involve the preparation or formation of alkaline bleach solutions experience an aggressive corrosive environment that can attack equipment constructed of both non-exotic metals and fiberglass reinforced plastic composites. Properly fabricated fiberglass reinforced plastic composites have satisfactorily resisted the corrosive attack of stable alkaline bleach. However, the ability of any fiberglass reinforced plastic composite to successfully withstand the corrosive effect of unstable bleach has been questionable. It has been reported that alkaline bleach becomes unstable and forms a more corrosive environment when the pH of bleach decreases. In order to determine the aggressiveness of this environment, a study was undertaken to observe the corrosive effect of several alkaline pH adjusted bleach solutions on various types of vinyl ester resin composite laminates at both 150° and 210°F. Results indicate that bleach solutions in the lower pH ranges are generally less corrosive towards the different resin composite systems observed than bleach solutions maintained at the higher pH ranges. The increase in temperature from 150° to 210°F also produced an increase in the corrosion rate by at least a factor of 2 in most cases. A fire retardant bis A epoxy vinyl ester resin and two bis A epoxy vinyl ester resins were used in preparing the different fiberglass reinforced plastic composite laminates. The fire retardant bis A epoxy vinyl ester resin gave improved corrosion resistance over the two bis A epoxy vinyl ester resins. The catalyst systems and veil materials used, as well as resin cure, had a definite influence on the resins’ composite systems’ ability to resist corrosive attack.

Abstract Two fiber reinforced polymer composites were examined for susceptibility to microbiologically influenced degradation. Composites, resins, and fibers were exposed to sulfur/iron-oxidizing, calcareous-depositing, ammonium- producing, hydrogen-producing and sulfate-reducing bacteria (SRB) in batch culture. Surfaces were uniformly colonized by all physiological types of bacteria. Epoxy and vinyl ester neat resins, carbon fibers, and epoxy composites were not adversely affected by microbial species. SRB degraded the organic surfactant on glass fibers and preferentially colonized fiber-vinyl ester interfaces. Hydrogen-producing bacteria appeared to disrupt bonding between fibers and vinyl ester resin and to penetrate the resin at the interface.

Abstract A new patent-pending resin technology incorporated into the epoxy/polysiloxane part A portion of a two-component coating system, using an amino-silane curing agent, has shown significant improvements in flexibility, gloss and color retention. Corrosion resistance and adhesion to non-sandblasted metal substrates have also shown improvements. The new resin technology may be considered for low-VOC and HAPs coating systems. The new resin technology is inherently low in viscosity, which exhibits benefits during high shear coating spray application. The new resin technology can be incorporated into the grind paste or as a postaddition to the coating formulation without affecting the coating’s final performance. Results of QUV-B, Conical Mandrel Bending after heat aging, and corrosion resistance of fully formulated coatings comprising the New Flexible Polysiloxane Coating Modifier resin technology will be presented versus Control Systems.

Abstract:
Abstract The stress corrosion characteristics of uniaxial glass fibre reinforced thermosetting resin composites have been examined in Hydrochloric acid at room temperature and 80 °C. A simple technique based on linear elastic fracture mechanics (LEFM) is presented for characterising crack growth in these materials subjected to hostile acidic environments. The environmental stress corrosion cracking is investigated both for different types of resin and different types of glass fibre reinforcements. Two matrices were used: Bis-A epoxy vinyl ester resin (based on Bisphenol-A epoxy resin) and novolac epoxy vinyl ester resin (based on epoxidised novolac resin). Two glass fibre types were employed: standard E-glass fibre and “R”, a special type of E-glass with superior acid resistance. Model experiments using a modified double cantilever beam test with static loading have been carried out on unidirectional composite specimens in 1M Hydrochloric acid solution at room temperature and 80 °C. The rate of crack growth in the specimen depends on the applied stress, the temperature and the environment. Consequently, the lifetime of a component or structure made from GRP, subjected to stress corrosion conditions, could be predicted provided the dependence of crack growth rate on stress intensity at the crack tip is known. Scanning electron microscopy studies of the specimen fracture surfaces have identified the characteristic failure mechanisms. The most important findings of this work is that the selection of epoxy vinyl ester resins reinforced with “R” fibre exhibited superior resistance to crack growth at 80 °C compared to similar E-glass reinforced composites at room temperatures.

Abstract:
Abstract Coal tar epoxy have been widely used to protect immersed maritime steel structures against corrosion conventionally. But the tar epoxy coating is restricted for use in the future due to environmental concerns. A new generation of super high build epoxy is expected to provide prolong life time and maintenance-free coatings. In this paper, super high build epoxy resin coating was evaluated with laboratory performance tests, such as impact resistance test, water vapor permeability test, cathodic disbondment test, thermal gradient test, salt spray test and seawater exposure corrosion test and compared to tar epoxy resin coating according to the standard tests for offshore structures, especially regarding the service areas for tidal, splash and submerged zone. In conclusion, anti-corrosive properties and durability of the super high build epoxy resin coating were excellent compared with tar epoxy resin coating.

Full text
Abstract:
Waste NBR rubber gloves have become an environmental burden because the chemically cross-linked NBR gloves can’t be recycled. In this particular research, an initiative was made to turn the NBR waste glove into an oil absorbent mat by using the amount of chemical cross-linking inside the NBR waste glove triggered by solvents and with the help of epoxy resin as a binding agent. The absorption test used two types of oil: cooking oil and engine oil. To justify the relationship between the developed oil absorbent mat and its absorption behaviour, various tests, namely the Fourier transform infrared radiation (FTIR), scanning electron microscopy (SEM), and absorbency test, were conducted. Epoxy resin was used as a binding agent in the production of oil-absorbing mats made from waste NBR gloves. The NBR gloves mixed with binding agents of epoxy resin mats have proven to be an effective medium for oil absorbance purposes.

Full text
Abstract:
The flexibility of polybenzoxazine (BA) can substantially be improved by alloying with IPDI-based urethane prepolymers (PU) or with flexible epoxy (EPO732). The experimental results, i.e. flexural testing and dynamic mechanical analysis, reveal that flexibility of the rigid polybenzoxazine and the PU or th EPO732 alloys systematically increases with the amount of both tougheners due to the added flexible molecular segments in the polymer hybrids. The curing temperature of the benzoxazine resin at about 225 degree celcius shifts to a higher value when the fraction of BA in both resin mixtures decreases. Interestingly, the synergism in glass transition temperature (Tg) obtained from the peak of loss modulus in the dynamic mechanical analysis of BA/PU alloys is clearly observed, i.e. Tg of the BA/PU alloys are significantly greater (Tg beyond 200 degree celcius) than those of the parent resins, i.e. BA (Tg = 165 degree celcius) and PU (Tg = -70 degree celcius). However, this synergistic characteristic is not observed in the BA/EPO732 alloy systems. The synergistic Tg of BA/PU alloy at 70/30 mass ratio is found to be 221 degree celcius while that of BA/EPO732 at the same mass ratio is reported to be of only 95 degree celcius and further decreases with the amount of epoxy fraction. The phenomenon is explained by the ability of the PU fraction to substantially enhance the crosslinked density of the polymer alloys thus create the more connected network structure of the resulting alloys whereas the EPO732 shows almost negligible effects on the alloys crosslinked density or even reduce the alloy’s crosslinked density when the amount of this flexible epoxy is greater than 50wt%. Furthermore, the degradation temperature based on the 5% weight loss of the TGA thermograms of BA/PU alloys is found to be improved with the presence of the PU while the opposite trend is observed in BA/EPO732 systems. Finally, the char yield of both alloy systems is steadily enhanced with increasing the amount of the benzoxazine fraction due to the inherent high char yield of the benzoxazine resin comparing with the other two tougheners. The toughened polybenzoxazine using IPDI-based urethane prepolymer, e.g. 70/30 BA/PU, is thus the promising system for a tough and high thermal stability polymeric network for bulk or composite matrix applications.
