碳纤维增强碳基复合材料已广泛应用于航空航天、汽车等行业的热结构件制造。钻削是碳纤维增强碳基复合材料装配前加工的一种非常常用的方法。但由于其非均质性、各向异性和脆性等特点，使得钻孔质量难以保证。通常会出现一些严重的钻孔缺陷，如毛刺、分层和撕裂。因此，有必要准确预测碳纤维增强碳基复合材料在钻孔过程中的推力。因此，本文基于纤维增强聚合物复合材料的切削理论，提出了双向碳纤维增强碳基复合材料钻孔推力替代预测模型。基于张氏模型，根据被加工材料结构将切割变形区划分为三个区域，建立了切割唇的切割力。详细考虑了纤维取向的周期性变化。实验结果表明，推力预测值与实验值的相对偏差小于14.36%。
Carbon fiber–reinforced carbon matrix composites have been widely used for the manufacturing of thermostructural parts for several industries such as the aerospace and automotive. Drilling is an extremely common method used in the machining of carbon fiber–reinforced carbon matrix composites before assembly. However, their non-homogeneous, anisotropic, and brittle nature make difficult to guarantee the hole quality in drilling. Some severe drilling defects, such as burrs, delamination, and tear, usually occur. In this regard, it is necessary to accurately predict the thrust force in drilling of carbon fiber–reinforced carbon matrix composites. Therefore, in this article, based on the cutting theory of fiber-reinforced polymer composites, an alternative thrust force prediction model for drilling of bidirectional carbon fiber–reinforced carbon matrix composites is proposed. The cutting force of the cutting lips is established by dividing the cutting deformation zone into three regions according to the machined material structure based on the Zhang’s model in cutting of fiber-reinforced polymer. The periodic variation of fiber orientation is considered in detail. The experimental results show that the relative deviations of the predicted and experimental values of the thrust force are less than 14.36%.
