連續(xù)纖維增強熱塑性聚合物復合材料（CFRTPCs）具有輕質(zhì)，優(yōu)良的耐藥品、耐輻射和電氣性能，生產(chǎn)周期短、生產(chǎn)效率高，可重復或二次加工及易修補等，克服了熱固性聚合物復合材料韌性差、斷裂延伸率低，易發(fā)生早期應力開裂的缺點；也彌補了短纖維和中長纖維增強熱塑性聚合物復合材料承載力不高的缺點，廣泛應用在航天、航空、汽車、化工、電子和電器等諸多領域，且發(fā)展速度快，未來市場樂觀（CFRTPCs在2018-2121年間預計將保持4.38%的增長）。
目前CFRTPCs制造主要集中在歐洲和美國。2015年歐、美產(chǎn)量分別為31536噸和27516噸，總?cè)蚴袌隹傤~的62.30%。中國2011-2015年的生產(chǎn)增長率最高達11.42%。盡管中國存在巨大的市場增長空間，且數(shù)家公司、高校和研究所也在不遺余力地從事CFRTPCs的研制和生產(chǎn)，但在技術(shù)和產(chǎn)品性能方面，與國外領先制造商（如Lanxess，Polystrand等）相比，仍具有明顯的差距。
FPC課題組前期和吉林大學教育部特種工程塑料工程研究中心姜振華、張云鶴教授合作，設計開發(fā)了一系列不同耐熱等級的高流動性PEEK樹脂及其共聚物，并基于簡單的溶液浸膠、高溫模壓制備出CCFs/PEP-PEEKs層壓復合材料，相關研究成果發(fā)表在Composites Science and Technology（2018,165: 148-153）上，為制備大批量、高性能CFRTPCs提供了一種簡單、可行的設計、制備方法。

Abstract
Continuous carbon fiber (CCF) reinforced polymeric composites have attracted significant attention in the aeronautic and automobile industries. In this study, novel CCF/poly(ether ether ketone) (PEEK) composites with robust solvent resistance, excellent thermal stability and outstanding mechanical properties were successfully fabricated via a facile solution impregnation process, mainly ascribed to the introduction of the crosslinkable phenylethynyl pendant to PEEK (PEP-PEEK) with excellent solubility. After the crosslinking reaction, PEP-PEEK presented robust solvent resistance, good thermal stability, and high mechanical properties. The longitudinal tensile strength of the CCF/PEP-PEEK composites significantly improved to 1610 MPa, which was 19 times stronger than the longitudinal tensile strength of PEP-PEEK. In the meantime, the CCF/PEP-PEEK composites also had a higher long-term operating temperature, excellent thermal stability and high heat distortion temperature. This study was performed as part of a larger effort to provide a simple and feasible method for the preparation of high quality continuous fiber reinforced poly(ether ether ketone) composites.
