Abstract
Composite of improved flex fatigue life comprising 50 to 70 volume percent reinforcing filaments of carbon, aramid or glass uniformly coated with a polymer in a polymeric matrix. The Young's modulus of the filament coating polymer is intermediate the Young's modulus of the filament and the matrix polymer.
