摘要/Abstract

摘要： 采用铣削和钻削两种工艺方法，对Al/AFRP(Aramid fiber reinforced polymer，AFRP)和Al/碳纤维复合材料(Carbon fiber reinforced polymer，CFRP)共固化材料进行了制孔试验，研究了工艺参数对制孔质量和表面缺陷的影响，并结合切削力进行了机理分析。通过比较两种共固化材料的切削性能，以揭示不同加工方式下纤维材料断裂方式和表面创成机理的不同。试验结果发现，铣削过程中的轴向力较为分散，能够减少碳纤维复合材料制孔过程中的分层损伤、基体剥离等缺陷，对切屑的破碎效果较好，减少了孔壁剐蹭现象，因此更适用于Al/CFRP共固化材料的加工；在钻头加工条件下，切削过程从钻尖开始，材料去除范围更加集中，能够减少芳纶复合材料加工过程中的毛刺堆积缺陷，孔口质量提高了30 %，因此使用钻头加工Al/AFRP共固化材料的效果较好。研究结果表明，在进给速度为20 mm/min条件下，Al/FRP共固化材料的切削力平均降低67.25 %。特别地，最大降幅出现在铣刀加工Al/AFRP共固化材料，达到76 %。本研究揭示了不同材料切削机理的差异，为新型共固化材料的加工提供了理论基础，同时拓宽了复合材料的应用范围。

Abstract: This study employed milling and drilling processes to conduct hole-making experiments on Al/AFRP(Aramid fiber reinforced polymer，AFRP) and Al/Carbon fiber reinforced polymer(CFRP) co-cured materials, investigating the impacts of process parameters on hole quality and surface defects, while performing a mechanism analysis in conjunction with cutting forces. By comparing the cutting performances of the two co-cured materials, the study aimed to elucidate the different modes of fiber material fracture and surface formation mechanisms under various processing methods. The results indicated that the axial force during the milling process is more dispersed, which helps to reduce delamination damage and matrix peeling defects in the hole-making process of carbon fiber composites, thereby enhancing chip fragmentation and minimizing wall scratches. This makes milling more suitable for processing Al/CFRP co-cured materials. In contrast, under drilling conditions, the cutting process begins at the drill tip, which concentrates the material removal area and effectively reduces burr accumulation defects in aramid composites, resulting in a 30% improvement in hole quality. Consequently, drilling proves to be more effective for processing Al/AFRP co-cured materials. The research findings demonstrate that at a feed rate of 20 mm/min, the average cutting force for Al/FRP co-cured materials is reduced by 67.25%. Notably, the maximum reduction occurs during the milling of Al/AFRP co-cured materials, reaching 76%. This study reveals the differences in cutting mechanisms for various materials, providing a theoretical foundation for the machining of novel co-cured materials and expanding the application range of composite materials.
