Abstract

The multipass two-body abrasive wear behavior of coconut shell particle reinforced epoxy composites has been
evaluated. The composite samples were rubbed against the water proof silicon carbide abrasive grit papers of
600,800 and 1000 grade affixed on rotating disc of pin-on-disc wear testing set up under dry sliding conditions.
Taguchi L9 orthogonal array was used for the analysis. The experimental values of wear loss were transformed to
S/N ratio. The influence of each control factors was analyzed with S/N response table with the help of MINITAB
16 software. The effect of four independent variables, viz., abrasive grit, sliding velocity, normal load, and sliding
distance is considered for this study. Results revealed that abrasive grit has the highest influence of 48.92% on
wear behavior followed by the normal load (31.70%), sliding velocity (10.35%), and sliding distance (9.01%).
