Another important application of thermoplastic fibers such as poly ether ether ketone (PEEK), Poly etherimide(PEI), and VectranM andHS (Vectranis the trade mark of Hoechst liquid crystalline polymer) is in making thermoplastic matrix composites. Commingled yams of the reinforcement and matrix such as quartz/PEEK, glass/PEI, Vectran HS/M are used to make the composites wherein the matrix yarn fuses to form the continuous phase of the composite. 

A review (16) and a book (17) on the chemistry and properties of poly(ether ketones) have been published. PEEK is present in the market also in reinforced grades (glass or carbon fibers) as well as in yams or in powder for coatings. Fibers are marketed by ICI imder the trade name Zyex. PEEK found application in the transport, teletronics, and aerospace sectors, with the fabrication of injection-molded engineering components and circuit boards. PEEK materials have also foimd a place in medical technologies. For this purpose, their biological and toxicological safety has been certified (14).
