Abstract
A fiber-reinforced polymeric resin composite material useful for producing a shaped composite article having a high thermal stability and mechanical strength, and a low creep strain, comprises a thermoplastic polymeric resin matrix and a number of reinforcing individual fibers embedded within the polymeric resin matrix in such a manner that 10% to 70% by the number of the individual fibers are separated from each other through portions of the polymeric resin matrix and the remaining individual fibers form at least one fiber bundle.
Claims8
A fiber-reinforced polymeric resin composite material comprising:
- (A) a matrix consisting essentially of a thermoplastic polymeric resin;
- and
- (B) a number of reinforcing individual fibers extending substantially in parallel to each other and embedded within the polymeric resin matrix in a manner such that 10 to 70% of the number of individual fibers are separated from each other through portions of the polymeric resin matrix, while the remaining individual fibers come into direct contact with each other to form at least one fiber bundle.
