Abstract
The invention relates to an impact resistent syntactic foam-prepreg composite material comprising syntactic foam of microballoons in a matrix resin bonded to a compatible resin containing carbon fiber prepeg 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.
