Drilling of CFRP composite materials finds widespread applications in many engineering fields. The drilling of FRP composite materials is different from the approach adopted for the conventional materials. Fiber pull-out, spalling, fuzzing, fiber breakage, delamination are some of the problems encountered while drilling these materials. To reduce these defects and to investigate the suitability for many applications, a study of drilling of composite structures is required. This research describes the work material along with its properties, specifications and fabrication of CFRP composite plates. The different tool materials used in the present study along with its point angle are presented. The various drilling parameters and the responses are explained. The experimental setup and the experimental procedure are discussed. Finally, the experimental results obtained for each tool is tabulated.

Keywords: CFRP composite laminates; HSS, carbide and PCD drill bit, Surface roughness, Drilling parameters, Delamination factor, VMC

Article published in International Journal of Current  Engineering  and Technology, Vol.4,No.4 (Aug- 2014)
