Abstract:
A composite article formed by:(a) placing in a mold a continuous linearly intermixed fiber tow comprising an intimately, uniformly and continuously intermixed blend of (i) about 90 to about 30% by volume, based on the total fiber content, of spun, continuous, individual, thermoplastic polymer fibers having a melting point of at least 50Â° C. (ii) as about 10 to about 70% by volume, based on the total fiber content, of continuous, individual carbon fibers wherein there is substantially uniform distribution of the thermoplastic fibers and the carbon fibers within the intermixed tow; and (b) heating the tow under pressure to the flow temperature of the thermoplastic polymer fibers.
