Abstract

A composite having fibers of relatively high elastic modulus embedded in a matrix of relatively low elastic modulus is provided with an interphase of elastic modulus less than the matrix modulus and cohesive energy higher than the matrix cohesive energy. The resulting composite has enhanced strength and toughness.
