Abstract
The effects of fiber orientations on the grinding force and ground surface roughness in grinding 2D–Cf/C–SiC composites were investigated in this work. The characteristics of surface microstructure and the mechanism of the grinding phenomena are also discussed. The results show that the prominent removal mechanism for grinding the 2D-Cf/C-SiC composites is the brittle fracture, and the destruction of the composites is mainly via breaking of interfacial bonds, fiber fracture, and matrix cracking. The grinding force of different grinding surfaces follows the order: Surface B > Surface A > Surface C, and the surface roughness follows: Surface C > Surface A > Surface B. Grinding parameters, such as feeding speed, depth of cut, and wheel speed, have a great influence on the grinding force and surface roughness. This result suggests that this body of work offers a useful guideline for improving the design and processing of 2D–Cf/C–SiC composites.
