Drilling of Glass Fibre Reinforced Plastic
Nowadays composite materials are used in many industrial areas. The main application of these is the aircraft industry. Problematic points with machining of composite materials are tool wear, tool life, delamination and temperature during machining of polymer composite materials. Paper focuses on investigation of delamination at drilling of glass fibre reinforced composites. Experiments were planned on the base so called design of experiment - DOE. We observed the evolution of delamination at investigations, when we combined 4 different variables (vc, fz, tool, cooling system). We investigated the evolution of force relations, torques, dimensional and shape accuracy, considering on delamination. We processed results statistically, for processing we used software MINITAB and MATLAB. We summarized results in tables and graphs.
