Abstract
Even though near net shape manufacturing of fiber reinforced plastics (FRP) is possible, drilling is an unavoidable operation, particularly for assembly of structures/panels having holes of specified dimensional tolerance, surface texture and integrity. In the present work drilling tests were carried out on GFRP composites with conventional HSS (18-4-1) drill bit and then by modifying the drill geometry (web or chisel edge ) i.e. web thinning in order to show the effect of drill geometry in general and web (chisel edge) in particular on the performance of the drilling of GFRP composite. It is observed that the fiber orientations and drill geometry plays a vital role on the cut quality and delamination.
