连续纤维增强热塑性聚合物复合材料（CFRTPCs）具有轻质，优良的耐药品、耐辐射和电气性能，生产周期短、生产效率高，可重复或二次加工及易修补等，克服了热固性聚合物复合材料韧性差、断裂延伸率低，易发生早期应力开裂的缺点；也弥补了短纤维和中长纤维增强热塑性聚合物复合材料承载力不高的缺点，广泛应用在航天、航空、汽车、化工、电子和电器等诸多领域，且发展速度快，未来市场乐观（CFRTPCs在2018-2121年间预计将保持4.38%的增长）。

  目前CFRTPCs制造主要集中在欧洲和美国。2015年欧、美产量分别为31536吨和27516吨，总全球市场总额的62.30%。中国2011-2015年的生产增长率最高达11.42%。尽管中国存在巨大的市场增长空间，且数家公司、高校和研究所也在不遗余力地从事CFRTPCs的研制和生产，但在技术和产品性能方面，与国外领先制造商（如Lanxess，Polystrand等）相比，仍具有明显的差距。

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.
