다이어몬드 입자드릴에 의한 탄소섬유 에폭시 복합재료의 드딜링 특성에 관한 연구

The carbon fiber epoxy composite materials have some problems, for example, seperation between carbon fiber and epoxy, delamination of lamina etc. Also, the tool wear is very serious. Therefore, we need to improve the shape of drill and condtion of drilling if possible. In this study, machinability of the carbon fiber epoxy composite materials in drilling was experimentlly investigated to establish the efficient shape of drill.
