Abstract
Disclosed herein are thermoplastic polymer matrix compositions for a continuous fiber reinforced thermoplastic composite article, comprising at least one of poly(vinyl chloride) and/or chlorinated poly(vinyl chloride). Also disclosed herein are methods for formulating thermoplastic polymer matrix compositions suitable for impregnating continuous fibers for continuous fiber-reinforced thermoplastic composite articles, wherein the thermoplastic polymer matrix compositions have sufficient viscosity and thermal stability to impregnate continuous fibers and withstand thermal treatment at high temperatures and long residence times without decomposing.
