本文研究了铺层为[（0度/90度/45度/-45度）（3）]（s）的多向碳纤维增强塑料（CFRP）复合材料的可磨性。重点研究了切屑形成、材料去除机理、磨削表面特征和磨削力特性。与单向CFRP复合材料的结果进行了系统的比较。结果表明，多向复合材料的磨削力随磨削深度的增加而近似线性增加。所生产的碎片显示出细粉末和不同长度的断裂纤维的混合物。这与单向纤维增强复合材料的磨削不同，单向纤维增强复合材料中切屑的几何形状主要取决于纤维的取向。磨削多向复合材料的纵向表面粗糙度随局部纤维取向变化很大。在[-45度]的层片中观察到严重的损坏，例如纤维拔出。(C)2003 Elsevier B.

This work studied the grindability of the multidirectional carbon fibre-reinforced plastic (CFRP) composites with the panel layup of [(0degrees/90degrees/45degrees/-45degrees)(3)](s). Focuses were on the chip formation, material removal mechanism, ground surface features and grinding force characteristics. The results were systematically compared with the unidirectional CFRP composites. It was found that the grinding forces for the multidirectional composites increase nearly linearly with raising the grinding depth. The chips produced showed a mixture of fine powder and broken fibres of various lengths. This is different from grinding the unidirectional fibre-reinforced composites, where the geometry of chips was mainly dependent on the fibre orientations. The longitudinal surface roughness of ground multidirectional composites varied strongly with the local fibre orientations. Severe damages, such as fibre pullout, were observed with the plies of [-45degrees]. (C) 2003 Elsevier B.V. All rights reserved.
