Effect of particle size and weight percent of different wood dust on the tensile strength of glass fiber Epoxy/Saw dust composite using RSM

Abstract

Nowadays demands of glass fiber epoxy based composite is increasing very rapidly. In this investigation effect of particle size, weight percentage and types of saw dust powder on tensile strength is investigated. Response surface methodology was used for the analysis of specimens. Further analysis of variance is employed to investigate the effect of contribution of individual process parameters. Furthermore a regression model is developed to predict the tensile strength of the glass fiber epoxy/saw dust composite. Confirmation experiments validated that developed model is valid within the experimental domain. The peak value of tensile strength 18.72 MPa is observed at process parameters i.e. wood dust type of rubber, wt.% of 18% and particle size of 550.83 µm.
