In the present work SCFcarbon composite was prepared with a commercially available vinylester methyl ethyl ketone peroxide catalyst and cobalt napthenate accelerator. The prepared composite is aimed to use in aircraft application. The composite is treated to improve the characteristics of SCFCarbon. Drilling characteristics were studied for both treated and untreated composites. As per Taguchi orthogonal array of L8 eight experiments were conducted on the composites and machining characteristics like thrust force surface roughness and amplitude of drill vibration were measured. Interaction effect of parameter on the machine characteristics was studied using response surface methodology. Analysis of variance was also used to identify significant parameters for the three machining characteristics. A multi response optimization technique was used to optimise parameters for minimization of thrust force surface roughness and amplitude of drill vibration.
