Multi‐objective optimization of wear performance of epoxy composites by gray‐based response surface methodology

This study is to optimize the tribological performances of epoxy (plain), composite of epoxy/strand mat E‐glass fiber, and hybrid composite of epoxy/strand mat E‐glass fiber/carbon (particles). Experiments are carried with respect to central composite design in response surface methodology. Input parameters like speed (N), load (L), sliding distance (D) along with three different samples (S) were considered for the study. Gray relational analysis based on response surface design method is embraced to identify optimal parameters for attaining minimum weight loss and minimum coefficient of friction. According to this study, epoxy/E‐glass fiber/carbonp composite were found to have good wear resistance as well as lower coefficient of friction. Optimization of wear performance of epoxy composites.
