摘要

a method of forming a carbon fiber reinforced polymer matrix composite by distributing carbon fibers or nanotubes in a fused polymer phase comprising one or more fused polymers; and applying a succession of shear deformation events to the fused polymer phase such that the fused polymer phase breaks the carbon fibers successively with each event, producing reactive edges on the broken carbon fibers that react with and cross one or more. polymers. The composite shows improvements in mechanical properties such as stiffness, strength and impact energy absorption.
