Abstract

The focus of this study is to characterize the mechanical properties of a composition prepared fromwood flour and thermoplastic Polyurethaneat different ratios. Wood flour was mixed with polyurethane at 30%, 40%, 50%, and 60%. Mechanical properties of the composites have been measured intension, compression, and impact tests. Analyseshave shown an increase in tensile strength with by increasing wood flour content up to 40%, then it decreases when the proportion of wood flourbecomes 50% and 60%. Tensile modulus showed an increasing trend with the increase of fiber content up to 50%, then it drops slightly when the reinforcement ratio becomes60%. Results of compression test showed that 40% reinforcement loading have the peak of compressive strength. High impact resistance was observed with 40% wood flour content. A significantdecrease in impact resistance was observed when the wood flour content ratio exceeded 40%.
