激光-等离子体协同处理增强CFRP-6061铝合金异质界面连接及服役性能研究
Interfacial Connection and Service Performance of CFRP-6061 Aluminum Alloy Enhanced by Laser-Plasma Co-Treatment
摘要
Abstract
Carbon fiber reinforced polymer(CFRP)-aluminum alloys have the advantages of both CFRP and aluminum alloys,but their different properties make the connection challenging.In this study,the response surface method(RSM)was used to optimize the laser and plasma processing parameters for treating the 6061 aluminum alloy(AA 6061)surface.The AA 6061 surface was subjected to laser-plasma co-treatment with the optimized parameters.The CFRP-AA 6061 were prepared by the co-curing method.The interface properties of the CFRP-AA 6061 were evaluated by using the climbing drum peel(CDP)test.The single lap layer shear(SLLS)strengths of different treatment procedures under different service aging conditions were investigated.The optimal laser processing parameters included a laser scanning line spacing of 0.115 mm,a laser scanning rate of 102.719 mm/s and a laser frequency of 10.763 kHz,resulting in an average peel strength of 103.76(N·mm)/mm.The optimal plasma processing parameters included a gas flow rate of 597.383 L/h,a processing distance of 5.821 mm and a processing time of 173.132 s,resulting in an average peel strength of 66.39(N·mm)/mm.Under the optimal laser-plasma co-treatment condition,the average peel strength can reach 113.02(N·mm)/mm,and the interfacial connection is better under different service aging conditions.This research can provide a reference for the interface treatment of composite-metal heterogeneous connections.关键词
