Abstract
The conventional homogeneous materials cannot longer satisfy the growing demands on product capabilities and performance effectively due to the advancement in products design and materials engineering. Therefore, the fibre reinforced composites (FRCs) with better properties and desirable applications emerged. These enhanced qualities of the FRCs have emphasized the need for analysing their machinability for further improvement of performance. Hence, this paper presents a comparative investigation on the effects of drilling parameters on delamination and surface roughness of 19/HFRP and MTM 44-1/CFRP composite laminates, using HSS drills under dry machining. The results obtained depict that increase in feed rate caused an increase in delamination and surface roughness of both specimens, unlike cutting speed. Generally, the minimum surface roughness and delamination factor of the two specimens for the optimum drilling were associated with feed rates of 0.05-0.10 mm/rev and cutting speed of 30 m/min.
