CFRP激光表面预处理及其对胶铆混合连接接头性能影响
CFRP laser surface pretreatment and effect on properties of adhesive-riveted hybrid joints
摘要
Abstract
CFRP has been widely recognized for its excellent mechanical properties,and high-performance joining techniques between CFRP and other materials have become an important research direction in aerospace and other fields.In practical engineering applications,adhesive-riveted hybrid joining is a commonly used technique.Laser surface pretreatment,as a critical step in the bonding process,can modify the surface microstructure of the material,thereby effectively improving the joint performance.In this study,for the adhesive-riveted hybrid joining of CFRP,the relationship between the number of laser scans and the depth of surface grooves on CFRP is experimentally determined,and the influence of groove depth on joint strength is analyzed.Furthermore,the effects of laser surface treatment parameters on the failure mechanism of CFRP/Al adhesive-riveted hybrid joints are investigated.The results show that the ultimate load of laser-pretreated adhesive-riveted hybrid joints is at least 4.7%higher than that of untreated joints.The shear strength of CFRP/Al adhesive-riveted hybrid joints increases with the depth of surface microgrooves.However,when the groove depth exceeds 48 μm,bubble defects appear in the adhesive layer,adversely affecting the overall mechanical properties of the joint.关键词
