Effect of Salicylic Acid / Ethanol Treatment on Tensile Properties and Morphology Analysis of Recycled High Density Polyethylene / Wood Fiber Composites

Article Preview

Abstract:

The effect of salicylic acid as a coupling agent on the tensile properties, and morphology analysis of recycled high density polyethylene/wood fiber (rHDPE/WF) composites were studied. Both composites rHDPE/WF and rHDPE/WFM (treatment with salicylic acid) were prepared using Brabender Plasticorder at temperature of 160°C and rotor speed of 50 rpm. The result indicated that rHDPE/WFM composites with salicylic acid exhibit higher tensile strength and modulus of elasticity but lower elongation at break than rHDPE/WF composites. The SEM micrographs showed that the wood fiber was more widely dispersed in the rHDPE matrix with addition of ethyl salicylate than rHDPE/WFM.
