✦ Synopsis

Carbon fiber composites based on tetrafunctional epoxy resin N,N,N,N-tetraglycidyl-2,2bis[4-(4-aminophenoxy)phenyl]propane modified with cardanol were investigated. The differential scanning calorimetric technique was used to study the curing reaction of the neat resins. The dielectric properties of the composites were compared. The use of cardanol in epoxy resins at cardanol/epoxy molar ratios less than 0.3/1 improved the chemical resistance as well as the mechanical properties of the composites, such as the flexural strength and modulus, tensile strength and modulus, and interlaminar shear strength. Higher cardanol contents decreased such properties. The highest properties of the composites were observed with the epoxy-cardanol resin having a cardanol/epoxy molar ratio of 0.3/1. 0 1996
