Wavelet based pseudo color scaling for optimizing wear behavior of epoxy composites

Abstract

Abstract Application of polymer matrix composites in mechanical systems, where relative motions are involved, requires an investigation on the tribological performances of the composites. The prime objective of this work is to identify the optimum combination of input parameters such as speed N (rpm), load L (N), distance D (m) and material for minimum weight loss and minimum coefficient of friction. The performances are measured after performing experiments (full factorial) using pin on disc setup. Wavelet based pseudo color scaling and wavelet fusion methods are adopted to identify the optimum conditions. Accordingly, high speed, low load, moderate distance applied on epoxy with glass fiber and carbon particles is found to be optimum for minimum weight loss and minimum coefficient of friction.
