Experimental Investigations on Drilling of GFRP Composite using Solid and Hollow Drill Point Geometry

M Kannan, Vivek Sharma, Mukesh Kumar


Fibrous composite material are widely used because of its various enhanced properties as com- pared to the conventional material. Machining of these Composite materials is entirely different as compared with the conventional materials because machining depends upon the physical and me- chanical properties of the fiber, amount of fiber, type of fiber and the chemical composition of the fiber in the composite. In this paper conventional drills of solid and hollow drill are used to drill holes and its effects are studied on Glass fibre reinforced polymer composite(GFRP) prepared by hand lay up method. Implications of tool geometry ,speed, feed on delamination and machining time has been studied.
