Abstract

In this study, response surface methodology (RSM) was used to optimize preparation of biocomposites based on rHDPE and rice husk (RH) filler. RH is an agriculture waste which has the characteristic of wood and being used tremendously in wood plastic composites. The effects of pressing temperature, pressing pressure and pressing time on tensile strength were investigated. A Box Bechken design was employed to determine the optimum preparation condition of the biocomposites to obtain the highest tensile strength. A second-order polynomial model was developed for predicting the tensile strength based on the composite design. It was found that composites were best fit by a quadratic regression model with high coefficient of determination (R2) value. The selected optimum pressing condition was 180°C at 1000 psi and 9 min of pressing, leading to a desirability of 97%. Under the optimum condition, the composites were then prepared containing 10, 20, 30, 40 and 50 wt. % of RH fibers. The tensile strength and the tensile modulus of the biocomposites shows a good trend, respectively.
