摘要

摘要: 碳纤维增强复合材料是一种典型弹脆性材料,其纤维铺层方向与材料加工性能、破坏机理和切削质量有着密切的关系。针对复合材料各向异性的特点,利用Abaqus/Explicit有限元仿真软件,基于Hashin失效准则,建立碳纤维复合材料单向纤维铺层二维正交切削宏观模型。研究不同铺层方向条件下纤维和基体的破坏机理,开展复合材料平面铣削试验,并将试验加工得到的铣削表面与仿真结果进行了比较,验证了模型的合理性。

Abstract: As an elastic-brittle material, the fiber ply orientation of carbon fiber reinforced plastics (CFRP) shows close relationship with the material properties, the cutting mechanism and the machining quality. The cutting process of CFRP is a very complex process of elastic-brittle fracture. In this paper, the finite element simulation of cutting and destruction of the composite with Abaqus/Explicit software are studied, and the two-dimension orthogonal cutting model is created with Hashin failure criteria. Based on the model, the cutting process and the damage mechanism under different fiber orientations are studied. The experiment is also performed to confirm the validity of the model.
