Outline of Final Research Achievements

Recently, carbon fiber reinforced plastics (CFRP) have been widely used in various fields such as aircraft, cars, sporting goods, and so on.CFRPs have good characteristics such as light weight, high strength and rigidly. However,CFRP
material was difficult to machine, especially machining of deep hole was difficult.In this study, it was establish to machining method and evaluation technique of CFRP.As the reuls, new electrical discharge method was developed and can make special surface property for CFRP material.

Academic Significance and Societal Importance of the Research Achievements

本研究により従来,加工が困難とされているCFRPの微細加工が可能になった。また加工条件の制約は受けるが,理論値を超える高密度な炭素繊維を有する加工面の発現が可能になった。この発現現象は解明されておらず,今後の学術的課題となる。高密度な炭素繊維面が創成できると新しい材料特性の発現が期待できる。
