Review on joining process of carbon fiber-reinforced polymer and metal: methods and applications

摘要:

碳纤维增强树脂基复合材料(CFRP)在航空、汽车、舰船、海洋等工业中用量迅速增加。同时,如铝合金等金属材料在这些工业中仍然广泛应用。因此,CFRP和金属材料之间的连接技术是航空、汽车等此类工业中所面临迫切需要解决和发展的关键问题之一。本文综述了CFRP和金属连接技术的一些研究成果。总结了胶接连接、螺栓连接、焊接、金属插入连接以及基于塑性变形连接(如自穿孔铆接、热铆接、无铆链接、摩擦焊接等)技术的实现和连接材料类型范围。指出了高性能、轻量化、高可靠性的CFRP-金属混合接头进一步研究发展所要解决的问题。

Abstract:

The use of carbon fiber-reinforced polymer (CFRP) in aviation, automobile, marine and offshore, etc. increases sharply. The metals such as aluminum alloy are still widely used in these industries. Then, the joining technology of CFRP-metal is one of the key problems urgently to be solved and developed in these industries, especially in aviation industries. Thus, this paper gives a review on the joining processes of carbon fiber-reinforced polymer and metal. The implementation processes and joining material types of adhesive bonding, bolt connection, riveting, welding, “z-pin” (pin inserts), and joining (such as self-pierce riveting, hot riveting, mechanical clinching, friction welding) by plastic deformation, were summarized. Some future researches and developments of high-performance, light-weight, and high-reliability CFRP-metal hybrid joint were highlighted.
