摘要
连续纤维增强热塑性复合材料(CFRTP)可循环使用,具有高比强度和比刚度、良好的耐腐蚀性、耐冲击性、耐热性、低成本以及设计灵活性,被广泛应用在汽车、船舶、航空航天、国防等领域。本文从纤维与基体出发,综述了CFRTP的加工工艺的研究进展。文章主要涵盖4方面的内容:首先介绍用于制造结构复合材料的典型热塑性基体和高性能纤维,然后介绍连续纤维的表面处理和连续纤维热塑性预浸料的制备;之后介绍CFRTP的热成型和树脂传递模塑(RTM)以及一些新开发的CFRTP成型技术,详细介绍有关工艺改进和参数优化的实验和数值研究;最后展望了CFRTP的未来研究重点及发展趋势。
Continuous fiber-reinforced thermoplastic composites(CFRTP)have distinct advantages in recyclability,high specific strength and stiffness,corrosion resistance,enhanced impact toughness,heat resistance,cost effectiveness and design flexibility.With the rapid increase of CFRTPs as structural load-bearing materials in automotive,marine,aerospace,and military applications,more attention has been paid on the forming process of CFRTPs structural compo-nents using well-prepared thermoplastic prepreg.This article presents a survey of the literature on key technologies of forming process of CFRTPs in structural applications.First,some typical thermoplastic matrices and high-performance fibers used in structural applications are described,and then recent advances in the surface treatment of continuous fiber and preparation of continuous fiber thermoplastic prepregs are explored.Two major approaches—“subtractive”approach and“additive”approach—for the surface treatment of continuous fiber of CFRTPs are reviewed.As for the forming technology,this article highlights thermoforming and resin transfer molding(RTM)of CFRTPs as well as some newly developed techniques for CFRTPs forming.Experimental and numerical studies on process improvement and pa-rameter optimization are reviewed.Finally,future research focal points and trends for CFRTPs are described.
