Impact resistent composites

An impact resistent synthetic foam-prepreg composite material comprising at least one layer of a thin film of uniform thickness of a syntactic foam containing rigid microballoons in a resin matrix laminated to a prepreg construction of continuous filaments of high modulus fiber in a thermosetting resin matrix in which the syntactic foam is one or more thin uniform layers located within the composite material sufficiently close to an impact prone surface of the composite to enhance the composite's ability to withstand the impact through such surface and wherein the matrix resin of the syntactic foam is compatible and cocurable with the resin matrix of the prepreg.
