Abstract
A reinforced carbon-carbon (RCC) composite material has improved impact resistance. The RCC composite material is formed from a fiber reinforcement of layers or plies of thin ply carbon fiber fabric impregnated with a carbon matrix. Carbon nanotube reinforcement in the matrix further improves impact resistance. The stacking arrangement of the plies of the thin ply fabric also further improves impact resistance.

A reinforced carbon-carbon composite material, comprising:
- a plurality of plies of a thin ply carbon fiber fabric arranged in layers, each ply comprising ribbons woven together, each ribbon having a width of at least approximately 15 mm, a crimp angle between crossing fibers of each ply less than 9°, and each ply having a thickness no greater than 0.006 inch;
- a matrix of carbon material infiltrating pores of the carbon fiber fabric;
- and
- a plurality of carbon nanotubes dispersed within the matrix.
