HIGH CHAR YIELD THERMOPLASTIC POLYMERS BLENDS AND CORRESPONDING ARTICLES AND APPLICATIONS
Described herein are thermoplastic polymer blends (hereinafter referred to as "polymer blends") comprising a thermoplastic polymer and mesophase pitch, where the thermoplastic polymer comprises a polyarylene sulfide ("PAS"), a polyaryletherketone ("PAEK") or a polyphenylene ("PP"). As used herein, "thermoplastic polymer" excludes reference to pitch (mesophase or otherwise). Surprisingly, the polymer blends have significantly increased char yields, relative to those predicted. Furthermore, the polymer blends have desirable viscosities which make them suitable to traditional thermoplastic polymer techniques. Based at least in part upon the char yields and viscosities, the polymer blends are particular desirable for use in the formation of carbon fibers, thermoplastic prepregs, carbon-carbon composites and thermal protection systems.
Described herein are thermoplastic prepregs comprising an organic polymer matrix and a carbon fiber substrate. The polymer matrix comprises a polyphenylene polymer, described in detail below. The thermoplastic prepregs are particularly suitable for carbon-carbon composites ("C/C composites"). In particular, due at least in part to the significantly improved char yields and conversion to laterally ordered graphite-like carbon during pyrolyzation, the polyphenylene polymers described herein provide for improved C/C composites, both structurally and based upon processing efficiency. Also described herein are methods for manufacturing the thermoplastic prepregs and green bodies and C/C composites made therefrom.
