Aim: The main objective of this study is to compare roundness of the kevlar fibers with silica nanoparticles as filler in addition to epoxy and hardener composites in comparison with kevlar fibers with carbon nanotubes as fillers. Materials and Methods: The method is based on comparison of roundness for kevlar fiber with 3% volume fraction of Carbon nanotubes as filler (N=20) and Kevlar Fiber with 3% Silica nanoparticles as filler (N=20). Kevlar fiber is reinforcement material, Epoxy LY556 and hardener EY951 are matrix materials. Here the Novel Taguchi method is used for calculating roundness for drilling operations
