Radially Grown Graphene Nanoflakes for Tough and Strong Carbon Fiber Epoxy Composites

A long-standing challenge in structural material design is the simultaneous attainment of high strength and toughness, a conflicting requirement rarely met in engineering materials, with important technological applications in aerospace, defense, automobile, and marine industries. Motivated from examples in biological materials, to address this challenge, we demonstrate that strong and damage-tolerant carbon-fiber-reinforced polymers (CFRPs) can...
