摘要
碳纤维增强复合材料(特别是碳纤维增强树脂基复合材料和碳/碳复合材料)具有比强度和比模量高、耐高温、抗腐蚀等特点,被广泛应用于航空航天等领域。由于碳纤维增强复合材料硬度高、脆性大、层间剪切强度低等特点,使其在加工中容易出现毛刺、分层、撕裂等加工缺陷,并且刀具磨损快、耐用度低。针对碳纤维增强树脂基复合材料和碳/碳复合材料的加工问题,从铣削和钻削两个方面讨论了加工参数、加工刀具、切削力预测以及超声振动钻孔和螺旋铣孔等方面的技术,总结了目前提高碳纤维增强复合材料加工质量的工艺方法。
Carbon fiber reinforced composites(CFRCs), such as carbon fiber reinforced polymer(CFRP) and carbon/carbon(C/C) composites, are widely used in the fields of aeronautics and astronautics due to their superior properties, such as high specific strenth, high specific modulus, withstanding high temperatures and high resistance to corrosion. However, CFRCs is difficult to machine due to the high specific stiffness, brittleness, and low shear strength between layers, which can result in burr, delamination, tear and rapid wear of cutters. This paper is aimed to solve the milling and drilling problems of CFRP and C/C composites, and the technologies such as machining parameters, tool materials and geometry, prediction of cutting force, ultrasonic vibration machining and helical milling holes have been reviewed. This review paper also summarizes the processing methods of improving the quality of CFRCs.
