Natural fibers are renewable materials and have the ability to recycle. But, they are hydrophilic in nature and exhibit poor resistance to moisture.The main associated in developing new composite is adhesion property existing between fiber and matrix which can be enhanced by chemical variation which result in reducing hydrophilic nature. The powder with small particles was preferred since when the size of the particle decreases the intermolecular force adhesion increases. In this research work, matrix involving polyester resin possessing 62.07 of molecular weight (Mw) combined with rice husk (RH) to create an Hybridized Wood-Plastic Composite (HWPC). The impact of contribution of RH, wood powder by both contribution percent and its particle size are evaluated by investing its flexural, tensile and impact properties of HWPC. The investigation infers that by analyzing the percent of RH, wood powder, polyester resin matrix by weight ratio, it is inferred that the wood powder proportion increment increases the tensile property. Meanwhile, after reaching its maximum bar limit, it causes the impact and tensile property to get minimized rate. From mechanical properties analysis it results that high flexural strength can be obtained by smaller RH size utilization where it increases the interaction between RH and wood powder due to reduced voids and cavities which are obtained from the analysis of a scanning electron microscope (SEM) analysis.
