碳纤维增强聚合物(carbon fiber reinforced polymer, CFRP)-铝合金兼具CFRP和铝合金的优点，但由于两种材料性质不同，二者的连接比较困难。该文利用响应面法优化了激光和等离子体处理6061铝合金(AA 6061)表面的工艺参数，并在此参数下对AA 6061表面进行激光-等离子体协同处理，之后采用共固化法制备CFRP-AA 6061。通过滚筒剥离试验评估CFRP-AA 6061界面性能，探究了不同服役环境条件、不同处理方式下，CFRP-AA 6061的单层搭接剪切强度。研究发现激光处理最优参数为激光扫描线间距0.115 mm、激光扫描速率102.719 mm/s、激光频率10.763 kHz,此参数下CFRP-AA 6061平均剥离强度最高可达103.76 (N·mm)/mm;等离子体处理最优参数为气体流量597.383 L/h、处理距离5.821 mm、处理时间173.132 s,此参数下CFRP-AA 6061平均剥离强度最高可达66.39 (N·mm)/mm。两种处理方式在最优参数下的协同处理可使CFRP-AA 6061平均剥离强度达到113.02 (N·mm)/mm,并且在不同服役老化条件下表现出更优良的连接强度。该方法可为复合材料和金属异质连接界面处理提供参考。
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 of0. 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 of597. 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 laserplasma 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.
