Experimental and Numerical Optimization based Approach for Fibre Reinforcement in Rotomolding

Abstract

This study deals with the experimental analysis of fiber reinforcement of rotational molding processes and its numerical model based evaluation. The experiments are carried out to get patterns, using linear low density polyethylene (LLDPE) and glass fiber, to improve its surface finish, strength and hardness. For that design of experiment (DoE) is performed and then various experiments has been conducted. The theoretical optimum value is obtained and is compared with the experimental values. The optimum value by experimental calculations i.e., the weight of LLDPE and weight of fiber, with constant time, is in the permissible error with the theoretical value. This justifies that the experimental designs obtained are of optimum/local optimum value. Furthermore using a random population of points is generated and factors, which can improve the optimum design, are identified and reported
