Abstract
A fiber reinforced plastics comprises a resin and chopped strands dispersed in the resin, wherein the chopped strands comprise glass fiber chopped strands composed of cut assemblies of glass filaments and high elastic chopped strands composed of cut assemblies of high modulus inorgtanic filaments having higher elastic modulus than the filaments and having 3000 or less number of assembled filaments. By this arrangement, the both chopped strands are closely and uniformly dispersed in the resin and the force interaction between the both chopped stands are enhanced. The resultant plastics has remarkably improved strength and fatigue durability, and higher rigidity than conventional ones.
