Composite materials are the emerging material for different applications in various fields, due to high strength to weight ratio, high stiffness &corrosion resistance properties. For assembly of two composite components, drilling is the first step for fixing with any type of fasteners. It is one of the most commonly used secondary manufacturing processes. Any process rejection during drilling is a serious loss in manufacturing of commercial products. Comparing to Metallic materials, composite laminates due to anisotropy and nonhomogeneity in nature creates difficulties in the drilling process. When drilling parts made of Carbon Fiber Components, internal defects such as, cracking, uneven distribution of plies & delamination occurs due to uneven distribution of the drilling loads. This study presents experimental characterization of multi-directional CFRP to minimize the thrust force, hole roughness and delamination using optimum drilling parameters. Another objective of investigations is to calculate critical thrust force below which no delamination occurs.
