Effects of Drilling Generated Heat on Damage Factor in GFRP

Abstract:

Drilling generated heat is considered to have significant effect on the product. In this study, woven glass fiber reinforced epoxy composites were fabricated using Vacuum Resin Infusion technique. The composites were drilled using HSS twist drill bit at various drilling parameters. The temperature during drill was measured using infra red thermometer. The damage factor of drilled holes was measured using 3D non-contact surface measurement and correlates it with temperature. Results showed that low feed rate recorded maximum temperature and high fede rate showed lower heat generated during drilling. Damage factor measured at lower feed rate was high and low at high feed rate. This was considered due to evaporation of resin matrix.
