复合材料连接技术进展

Development of Composite Connection Techniques

介绍复合材料连接技术进展。主要介绍复合材料传统机械连接、胶接连接、缝合连接、Z-pin连接、混合连接、冷碾铆接等连接技术的工作原理、发展现状及影响连接性能的相关因素,比较这几种连接技术的优、缺点及应用性。结果表明:在复合材料连接工艺中,机械连接技术成熟、运用最广泛,混合连接是机械连接的拓展,缝合连接和Z-pin连接常作为辅助连接,胶接技术逐渐成熟,冷碾铆接研究较少,但有广阔的应用前景;各种连接的使用有相应的条件和要求,故连接性能的好坏涉及很多因素,比较复杂。

Developments of composite joining techniques are explored in this paper.It mainly discusses principles about the composite connection techniques,such as traditional mechanical joint,adhesive joint,stitched joint,Z-pined joint,combined joint and cold rolling riveting.Meanwhile,related factors which influence the performances of joint are introduced and the advantages,disadvantages and applicability of various joints are compared.The results show that mechanical joint is mature and most widely used.Combined joint is the expansion of mechanical joint,with stitched joint and Z-pined joint often used as auxiliary connection,adhesive joint becoming mature gradually.Cold rolling riveting has not been researched fully,so it has broad application prospect in composite joint process.Different joints have the corresponding conditions and requirements,thus the quality of joint performance involves many complex factors.
