Abstract
A composite material and method of manufacture involve a mixture of an epoxy resin and a hardener being essentially free of methylenedianiline and vinylcyclohexene dioxide. A fiber reinforcement is located within the matrix. Advantageously, the matrix has a glass transition temperature of at least 250° F. dry, the resin has a pre-hardening mixed viscosity of 500–1500 cP at 75° F., and the composite material has, upon hardening, an interlaminar shear strength of at least 6.5 ksi dry at 75° F. and at least 3.5 ksi dry at 250° F.
