A study of delamination characteristics (drilling) on carbon fiber reinforced IPN composites during drilling using design experiments

Abstract

Abstract The aim of this entire research approach is to produce the damage free drilling operation on the IPN composites by selecting the suitable cutting parameters. The standard combinations of polyurethane and vinyl ester resins were used as the matrix material to fabricate the IPN composite laminate with carbon reinforcement. To expedite this, the analysis of variance (ANOVA) and taguchi combination method was used. Based on the technique proposed in taguchi, the plan of experiments had been carried out, by opting the variant process parameters of the drilling; similarly, ANOVA was used to determine the drilling characteristics of the IPN laminate (carbon fiber) of various drill bits like Helical flute, Four-flute, Helical flute – K12 drill bits. The main objective upon doing this experiment was that, to establish the finest correlation between the feed rate and cutting velocity as the output of delamination in IPN laminate, by precisely choosing the multi linear regression analysis. At last, the evaluation tests were carried out to compare the obtained result with correlated analysis, as well it had shown significant agreement with each other.
