Abstract: Epoxy, prepared through aminomethyl 3,5,5-trimethylcyclohexylamine hardening of diglycidylether of bisphenol-A (DGEBA) prepolymer, toughened with polycarbonate (PC) in different proportions, and reinforced with carbon fiber, was investigated by differential scanning calorimetry, tensile and interlaminar shear strength testing, and scanning electron microscopy (SEM). A single glass transition temperature was found in all compositions of the epoxy/PC blend system. The tensile properties of the blend were found t… Show more

“…The interlocking of fiber‐matrix bonding has been shown by the arrows and loops in Figure 6(b). The increase in carboxyl group amount and absorbability on fiber surface may be responsible for these results 22. The flexural strength and tensile strength of carbon fiber/epoxy composites were improved due to the increased interfacial properties.…”

“…This modification did not improve the mechanical properties of the glass fiber reinforced plastics (GFRP) in quasi-static loading; however, the shear strength of epoxy-polysulphone GFRPs with 20 wt%, in a low-speed impact loading, increased by 20%-25%. Guduri and Luyt [12], studied an epoxy, prepared through aminomethyl 3,5,5-trimethylcyclohexylamine hardening of diglycidylether of bisphenol A (DGEBA) prepolymer, toughened with polycarbonate (PC) in different proportions, and reinforced with carbon fiber. They also found that the tensile and interlaminar shear properties of the epoxy-carbon fiber composites could be greatly improved by modification of the epoxy with the PC.…”

“…Traditional tougheners such as glass beads or rubber particles often have an adverse impact on the elastic modulus or thermo‐mechanical properties [1]. Recently, the incorporation of inorganic nanoparticles, such as nanoclay, carbon fiber, or metallic particles have drawn considerable attention because of the superior toughening effect observed on thermosetting polymers like epoxy resin [2–10]. Considering its applications in the microelectronic industry, studies on composites with both excellent mechanical and dielectric properties are greatly needed.…”
