| Abstract | ||||
| In this study, wood plastic composites (WPCs) were made with wood flour and polypropylene matrix (PP). Samples of WPCs were prepared through injection mould with different contents of wood flour (WF) (10%wt, 20%wt, 30% wt , 40%wt ). Malic anhydride (MAPP) was added as coupling agent to increase the interaction between the components. Physical, thermal, mechanical properties and immersion testfor different contents were investigated. This study discusses the sodium chloride absorption behavior of wood-plastic composite (WPCs). The weight gain of the test sample was determined and microstructures of the composites were examined by SEM analysis to understand the mechanisms for the wood–plastic interaction which affected the solution absorption. The results showed that the addition of 30%WF to WPCpp increases the hardness and tensile strength and then decrease. Wood flour improved the thermal stability of the PP matrix. The specimens with 40% wood flour had much higher solution content than all the other test specimens after immersed up to 60 days in solution. | ||||
