Carbon fibre reinforced epoxy composites

Abstract

Abstract Carbon fibre reinforced epoxy composites were fabricated from the matrix resin diglycidyl ether of bisphenol‐A and novel tetrafunctional epoxy resins N , N , N ′, N ′‐tetraglycidyl‐2,2‐bis[4‐(4‐aminophenoxy)phenyl]propane and N , N , N ′ N ′‐tetraglycidyl‐1,1 ′‐bis[4‐(4‐aminophenoxy)phenyl]cyclohexane using diaminodiphenyl methane as curing agent. Mechanical properties and chemical resistance of the composites were determined. Significant improvements in the mechanical properties were observed by adding epoxy fortifier to the resin‐curing agent mixtures before fabrication of composites.
