碳纤维复合材料在车身底板上的胶接研究及应用

Bonding Research and Application of Carbon Fiber Reinforced Polymer in Underbody

碳纤维复合材料(CFRP)是一种力学性能优异的材料,在国内大批量的汽车生产中,尚未实现CFRP与汽车车身的粘接应用。阐述了CFRP与铝合金材料粘接后的性能测试结果以及工艺流程的优化方案,通过测试结构胶在不同工艺下的固化强度以及外界因素对胶体粘接强度的影响,最终确定ES6车型CFRP粘接工艺流程以及各工序的工艺参数,在国内首次实现了将CFRP大规模(生产线产能20辆/h)应用于新能源汽车的车身结构件。

Carbon Fiber Reinforced Polymer(CFRP)is a material with excellent mechanical properties.The application of bonding CFRP parts with body has not been realized in mass automobile production in China.The article described the performance test on CFRP parts bonding with aluminum material and the optimization of process flow.The bonding process flow and process parameters of each process of CFRP on ES6 were ultimately determined based on the test of the curing strength of adhesive under different conditions and the influence of external factors on the adhesive bonding strength,Thus,for the first time,CFRP was applied to the body structure of new energy vehicle on a large scale(production capacity 20 job/hour)in China.
