Fiber-reinforced thermoplastics (FRTPs) have become a new generation of lightweight materials due to their superior mechanical properties, good weldability and environmental resistance, potential for recycling, etc. The market for FRTPs is expected to grow at a compound annual growth rate (CAGR) of 7.8% from 2022 to 2030. Many researchers have been trying to solve the problems in their processing and joining process, and gradually expand their application. Resistance welding is one of the most suitable techniques to join FRTPs. This paper summarizes the research progress of FRTP resistance welding in terms of the basic process of FRTP resistance welding, factors affecting joint performance, joint failure behavior, numerical simulation, weld quality control, and resistance welding of thermoplastic/thermoset composites. The objective of this paper is to provide a deeper insight into the knowledge of FRTP resistance welding and provide reference for the further development and application of FRTP resistance welding.
纤维增强热塑性塑料(FRTPs)因其优异的机械性能、良好的可焊接性和耐环境性、可回收潜力等,已成为新一代轻质材料。预计2022年至2030年期间,FRTPs市场将以7.8%的复合年增长率(CAGR)增长。许多研究人员一直在努力解决其加工和连接过程中的问题,并逐步扩大其应用范围。电阻焊是连接FRTPs最合适的技术之一。本文从FRTPs电阻焊的基本工艺、影响接头性能的因素、接头失效行为、数值模拟、焊接质量控制以及热塑性/热固性复合材料的电阻焊等方面总结了FRTPs电阻焊的研究进展。本文的目的是更深入地了解FRTPs电阻焊知识,并为FRTPs电阻焊的进一步发展和应用提供参考。
