摘要:
为研究CFRP不同纤维方向对其钻孔温度场分布和孔壁质量的影响,对不同纤维方向角处切削形式进行理论分析和ABAQUS仿真分析,并结合CFRP单向板、正交板和准各向同性板的钻削温度分布测试试验与钻削温度场仿真分析。结果表明,碳纤维方向对钻削温度场的分布规律影响很大;通过电子显微镜和共聚焦显微镜对不同纤维方向角处孔壁质量观测对比,发现纤维方向角在θ=0 °、θ=45 °和θ=90 °处孔壁质量较好,在θ=135 °处孔壁质量较差。

Abstract:
In order to study the influence of fiber orientation on temperature field distribution and hole-wall quality of CFRP, theoretical analysis and ABAQUS simulation analysis of cutting forms at different fiber orientation angles are studied. Through the drilling temperature distribution test and simulation analysis of drilling temperature field for CFRP unidirectional plate, orthogonal plate and quasi-isotropic plate, it was found that, the direction of carbon fiber has a great influence on the distribution of drilling temperature field. By comparing the quality of the pore wall at different fiber orientation angles observed by electron microscopy and confocal microscopy, it was found that the quality of the pore wall at 0 degree, 45 degree and 90 degree was better than the quality of the pore wall at 135 degree.
