Outline of Final Research Achievements

In this study, we proposed the dry grinding of carbon fiber reinforced plastic (CFRP) using the dry ice jet blowing on a diamond grinding wheel surface in the grinding process. As a result, it was experimentally clarified that the dry ice jet controls the wheel loading due to grinding of CFRP to lead the extent of wheel life and the increase of ground surface quality rather than the normal dry grinding. Furthermore, it was confirmed that some carbon fibers on the ground surface were finely crushed in wet grinding.

Academic Significance and Societal Importance of the Research Achievements

カーボン繊維強化プラスチックの高精度かつ高品質なドライ研削加工をドライアイスジェットの利用によって実現できることを明らかにしたことは,これまでに報告されておらず,本研究の学術的意義は高い.この成果は,航空・宇宙分野等におけるカーボン繊維強化プラスチックの加工コストを低減するとともに高品質化をもたらし,カーボン繊維強化プラスチックの大幅な利用拡大への布石となり得る.
