摘要：

In order to improve the CFRTP/Al alloy laser assisted joining strength, a hybrid surface pre-treating method was proposed in this paper. This hybrid method is adding PA material in the CFRTP/Al alloy interface and machining microtextures on the Al alloy surface. The joint strength enhancing mechanism with this hybrid method was investigated. The influence of the microtextures' dimension and the thickness of the added PA material on the CFRTP/Al alloy joining strength was discussed. The result showed that the maximum joining strength with this hybrid method was about 260% of that without any surface treating. The maximum joining strength about 37.5 MPa was obtained as the scanning line space was 0.1 mm in microtextures machining and the thickness of the added PA material was 80 mu m.
