Experimental Investigation on Machining Properties Carbon Fibre-Reinforced Epoxy Composites with the Addition of Nano SiC

Composites of carbon fibre reinforced in polymer matrix competes with aluminium–lithium alloys in aerospace applications because of its better balance between strength and the weight. The major issue in CFRP composites was reduced fracture toughness. To increase the fracture toughness of the composites, nanoSiC was added to epoxy resin as reinforcement. In this study, the machining properties of CFRP composites reinforced with nanoSiC were studied with weight fraction of SiC, spindle speed, and feed rate as process parameters and the torque was obtained as the response. The analysis and optimization of parameters were done using RSM technique. It has been observed that the parameter with 1% weight fraction of SiC, 50 mm/min feed rate, and spindle speed of 1500 rpm has given the maximum torque of 0.34 Nm.
