Drilling studies on carbon fiber-reinforced nano-SiC particles composites using response surface methodology

ABSTRACT

Polymer-based composites offers better mechanical, thermal, and physical properties which make them a potential material in the field of manufacturing and aerospace sectors. This paper investigates the influence of machining parameters on drilling of carbon fiber epoxy composites. The composites are fabricated by hand-lay technique with various weight fractions of nano-SiC (silicon carbide) particles. Experiments are performed by response surface methodology (RSM) for various machining parameters such as feed rate, spindle speed, and weight fraction of nano-SiC particles. Analysis of variance table is presented to study the dominant factors that affect the thrust force and delamination factors. Further RSM-based desirability approach is used to optimize the machining parameters which yield lower thrust force and delamination.
