Integrity of a hole is crucial in composite component assembly, which is typically prepared by drilling. In an assembly, practically multi-holes are prepared, and joint performance depends on many factors including hole geometries and quality. In this study, the effects of hole configurations including, hole size, D, gap between holes, M and distance to edge, E to bearing strength of carbon fiber reinforced polymer (CFRP) laminates with two serial holes is investigated. The holes were prepared using two types of drill bits, 4-flute solid carbide and conventional high-speed steel (HSS) for comparison. In terms of types of drill bit, the result showed that specimen drilled with carbide tools delivered higher bearing strength at 1256 MPa as opposed to 1092 MPa for specimens prepared by HSS drill bit. Furthermore, the measured hole diameter showed that carbide-drill bit produced better holes compared to HSS drill bit. Study concluded that for dual-holes case, selection appropriate hole configuration and drill bit plays a crucial role in maintaining CFRP structural integrity, primarily for aerospace and automotive high-performance applications.
