Study on Mechanical and Physical Properties of Wood-Plastic Nanocomposites after Fiber Surface Treatment

Haydar U. Zaman, Ruhul A. Khan

Abstract


Numerous composites based on high-density polyethylene (HDPE), wood flour (WF), and nanoclay (Cloisite 30B) were prepared by melt compounding followed by injection mold. This paper aims to evaluate the feasibility of using HDPE and underutilized WF as a material for the development of woodplastic composites, as well as the strengthening effect of nanoclay on them. To develop the poor interfacial interaction between the hydrophilic WF and hydrophobic HDPE matrix, as well as sodium dodecyl sulfate (SDS), nanoclay, maleated HDPE (MPE) was used as a compatibilizer. The influence of nanoclay and chemical treatment (SDS) of WF on the engineering properties of the wood-plastic composites made from HDPE. It was evaluated for physical features like water absorption as well as mechanical characteristics including tensile strength, modulus, and impact strength. In addition to increasing the nanoclay content, tensile strength and modulus have been improved using chemical treatment. Moreover, the impact strength observed a 3% rise by increasing the nanoclay content and then decreased. Overall outcomes recommend that the effects of chemical treatment will rise the impact strength. The physical testing outcomes exhibited that by growing the nanoclay content and SDS treatment application, the water absorption rate was decreased.
