Evaluation of Mechanical Property and Optimization of the Dry Sliding Wear Behavior of Carbon Black-Alumina-Epoxy-Glass Composite by using Design of Experiments

Abstract

The research work is mainly focused on investigating the effects of wear parameters: filler content (0%, 4% CB, 4% Al₂O₃,and 2% CB + 2% Al₂O₃), applied load (4.905, 9.810, 14.710, and 19.62 N), sliding distance (20, 30, 40, and 50 mm) by using Design of Experiments (DOEs) approach. The experimental results were analyzed using MINITAB V16 scientific graphical and data analysis software. Signal-to-Noise (S/N) ratio, analysis of variance (ANOVA) proved that the most influencing factor is filler and load and the minimum value of wear rate is obtained in 4% Al₂O₃ and moderate wear rate is shown by 2% CB + 2% Al₂O₃, specimen and it as a very good tensile strength of 20,759.785 N, and has a very minimum absorption of 0.784%. So finally (2% CB + 2% Al₂O₃) specimen is a very good wear resistance, tensile, and also absorption property. The overall improvement in the material property is achieved due to the very good dispersion and also establishment of interfacial bond between carbonblack and aluminium oxide nanopowder in epoxy resin filler. So it is a very economic and next generation material with highly improved properties which has a lot of applications.
