ABSTRACT:
High strength fiber-matrix composite materials are disclosed having low volumetric resistance inclusions in the matrix phase in order to resist transverse cracking of the matrix at those regions where the fibers are in closest proximity. Minute voids, air, solids or liquids serve to absorb the increasing volume change stress without cracking the matrix when the composite is deformed. The suppression of transverse cracking improves the overall performance of the composite.
