【摘要】：二维编织碳纤维复合材料因其具有优异的力学性能和耐疲劳、耐冲击等特点被广泛用于制造各类复合材料结构件中。但是由于二维编织碳纤维复合材料的多相性和特殊的纤维结构,其机械加工性能与传统金属材料和单向纤维复合材料差异较大。为了研究二维编织碳纤维复合材料的切削性能,提高加工效率和加工后的表面质量,基于正交切削实验对二维编织碳纤维复合材料在切削过程中的切削力进行测试,并利用金相显微镜和粗糙度轮廓仪来表征加工表面质量。实验结果显示,正交切削过程中纤维方向角度对切削力的大小影响巨大,当切削速度提高和切削深度降低时,复合材料展现了更好的切削性能,并且加工后的表面质量更高。
[Abstract]:Two-dimensional braided carbon fiber composites have excellent mechanical properties and fatigue resistance. Impact resistance and other characteristics are widely used in the manufacture of all kinds of composite structures. However, due to the multiphase and special fiber structure of two-dimensional braided carbon fiber composites, In order to study the cutting performance of two-dimensional braided carbon fiber composites and improve the machining efficiency and surface quality, the mechanical properties of the composites are different from those of traditional metal materials and unidirectional fiber composites. Based on orthogonal cutting experiment, the cutting force of two-dimensional braided carbon fiber composites in cutting process was measured, and the machined surface quality was characterized by metallographic microscope and roughness profiler. The fiber direction angle has a great influence on the cutting force in the process of orthogonal cutting. When the cutting speed is increased and the cutting depth is decreased, the composites exhibit better cutting performance and higher surface quality.
