| 摘 要： | 采用激光直接连接技术对铝合金(A6061)与碳纤维增强热塑性复合材料(Carbon Fiber Reinforced Thermal Plastic,CFRTP)进行连接,以接头抗拉强度作为评价指标,确定连接参数的影响规律及最优连接工艺。采用时效处理的方法提高接头连接强度,研究时效处理参数对拉伸强度的影响,揭示最优工艺参数下接头的连接机理。结果表明:发现连接界面中存在氧元素,并存在元素扩散,时效处理显著提高了CFRTP与A6061的接头强度,约为未时效处理的2倍,时效处理后界面连接紧密。

| Abstract: | In this paper,aluminum alloy(A6061)and carbon fiber reinforced thermal plastic(CFRTP)were joined by laser direct joining technology.Taking the tensile strength of joint as the evaluation index,the influence law of joining parameters and the optimal joining process were determined.The aging treatment method was adopted to improve the joint strength,the influence of aging treatment parameters on the tensile strength was studied,and the joining mechanism of the joint under the optimal process parameters was revealed.The results showed that oxygen element was found in the joining interface and there was element diffusion.The strength of the joint between CFRTP and A6061 could be significantly improved by aging treatment,which was about two times as much as that without aging treatment.The interface was closely joined after aging treatment. |
