碳纤维增强复合材料（CFRP）在加工过程中极易产生热损伤、毛刺、撕裂、分层等缺陷，严重制约了其广泛应用。为提高CFRP的加工质量，本文通过实验研究了激光、水辅助激光、铣削和钻孔四种加工方法下的CFRP制孔质量及其对抗拉特性的影响，在疲劳试验机上对加工后的CFRP进行了静态拉伸试验，并利用扫描电镜对CFRP试样拉断前后形貌进行了分析。通过比较CFRP加工后的宏微观形貌特征可知，激光和水辅助激光加工均会在孔周围产生热解产物，但后者的热解产物少于前者；铣削和钻削试样虽然没有产生明显热解产物，但撕裂和毛刺较为严重。对比拉断后宏微观形貌，激光和水辅助激光加工试样分层现象十分严重，铣削和钻削加工试样撕裂现象更加严重。静态拉伸结果表明，水辅助激光加工试样抗拉强度为560.5MPa，比钻削试样高2.8%，比铣削试样高4.4%，比激光加工试样高6.1%。因此，对于CFRP加工，水射流辅助激光可有效减小激光加工产生的热损伤，并可显著减少撕裂和毛刺等缺陷，同时试件具有较大的抗拉强度。
- Abstract:

Carbon Fiber Reinforced Polymer (CFRP) is prone to defects such as thermal damage, burrs, tearing, and delamination during processing, which severely limits its widespread application. In order to improve the processing quality of CFRP, this paper experimentally studied the drilling quality of CFRP under four processing methods: laser, water assisted laser, milling, and drilling, and their effects on tensile properties. Static tensile tests were conducted on the processed CFRP on a fatigue testing machine, and the morphology of the CFRP specimens before and after tensile fracture was analyzed using scanning electron microscopy. By comparing the macroscopic and microscopic morphology characteristics of CFRP after processing, it can be concluded that both laser and water assisted laser processing produce pyrolysis products around the pores, but the latter produces fewer pyrolysis products than the former; Although milling and drilling samples did not produce significant pyrolysis products, tearing and burrs were more severe. Comparing the macroscopic and microscopic morphology after fracture, the delamination phenomenon of the samples processed by laser and water assisted laser is very severe, and the tearing phenomenon of the samples processed by milling and drilling is even more severe. The static tensile results show that the tensile strength of the water assisted laser processed sample is 560.5 MPa, which is 2.8% higher than the drilled sample, 4.4% higher than the milled sample, and 6.1% higher than the laser processed sample. Therefore, for CFRP processing, water jet assisted laser can effectively reduce the thermal damage caused by laser processing, and significantly reduce defects such as tearing and burrs. At the same time, the specimen has a high tensile strength。
