| 摘要 |
The present invention is concerned with a fiber reinforced composite having excellent impact resistance and comprising a polymeric matrix containing a multiplicity of nonlinear, irreversibly heat set, resilient, shape reforming, elongatable, nonflammable carbonaceous fibers or, optionally, a blend of said carbonaceous fibers with other fibers, said carbonaceous fibers preferably have a sinusoidal or coil-like shape, a reversible deflection ratio of greater than 1.2:1 and an aspect ratio (1/d) greater than 10:1. |
