CFRP surface finishing using ceramic brush

摘要

This paper presents an investigation about the machinability of CFRP (Carbon Fiber Reinforced Polymers) by employing ceramic brush tool which consists of ceramic fiber bundles. The tips of ceramic fibers work as cutting edges. Continuous fibers provide stable and continuous grinding performances. Experiment has been carried out for different preload, depth of cut, feed rate and cutting speed conditions, where the surface roughness and the cutting force were measured. The surface roughness Ra was found to be between 1～1.5 μm. In the meantime the ceramic brush wear is also observed. Experimental results show that the feasibility of surface milling and finishing of CFRP using ceramic brush tools. Moreover, deburring was achieved very easily.
