Study on drilling process of CFRP (Carbon Fiber Reinforced Plastics)

Abstract

In structures for aerospace application CFRP (Carbon Fiber Reinforced Plastics) are widely used for parts of wing or tail structures of airplanes. Machining characteristics of this difficult–to–cut material introduce thermal problems which affect to downgrade the qualities of CFRP. Tool wear also caused by the high abrasive loads during the drilling process of the CFRP are critical for application as aerospace materials. In order to develop the cutting technique for CFRP, in this study, thermal influences of drilling parameters are observed with a various kind of cutting conditions. It is summarized that thermal effect on the drilling of CFRP is related to the material removal rate of drilling process.
