Abstract
Carbon composites, including carbon fibers, are disclosed and exhibit unique, advantageous mechanical properties, including inter laminar shear strength, compression strength, and resistance to forces applied at angles deviating from parallel to the longitudinal axis of the overall fiber. These improvements allow use of less material while conveying improved strength in myriad practical applications, reducing overall financial cost of fabrication, distribution, and practical utilization of resulting products. These advantages are optimized via utilizing inventive fabrication techniques that incorporate carbon filaments into carbon fibers, preferably incorporating carbon filaments including three-dimensional (3D) graphene platelets into said fibers. The filaments mechanically reinforce both individual fibers, as well as compositions including multiple fibers strung together in a single cord, by “crosslinking” the individual fibers with 3D graphene ligands. The combined result of these inventive efforts includes materials exhibiting superior mechanical strength and reduced mass relative to conventional carbon fibers.
