Abstract

Carbon fibre reinforced plastics has a lot of merit such as mechanical characteristic, lightweight, and thermal resistance. For using carbon fibre reinforced plastics, the cutting and drilling process is necessary, and the study of optimal cutting conditions is very necessary, too. Generally, CFRP needs the processes of lathe turning, drilling, milling and cutting after moulding. However, these processes cause such problems as sudden abrasion of the tools, heavy surface roughness and defective layer by crack and delamination. Therefore, the study to examine the conditions for the high precision products by minimising these problems is very important. In this study, a sample was made with a CFRP plate to take a drilling test under a set condition with a high speed steel drill. This dissertation is a study on the optimal drilling conditions of CFRP with various drilling condition. The drilling of these various specimens with different machining condition is performed.
