Abstract:
This study compared the mechanical properties of rice hull/high density polyethylene composites with those of maple wood-based counterparts. In addition, the effects of maleated polymers on the mechanical properties of rice hull and maple wood composites were investigated. Six types of maleated polymers (coupling agents) were used to improve mechanical properties, of the composites, especially notched Izod impact strength. The results suggested that the maple wood composites showed higher strength, modulus and impact strength than the rice hull composites. The results also indicated that maleated thermoplastic elastomers increased notched Izod impact strength of both composites dramatically. However, it was found that Maleated metallocene polyethylene was the most effective coupling agent that increased notched impact strength without sacrificing tensile and flexural strength.
