TENSILE MECHANICAL PROPERTIES OF WOOD FIBER / PVC COMPOSITES
To fully exploit the tensile mechanical properties of wood-plastic composites, the effects of the pine powder and rice husk powder content, particle size and the titanate coupling agent (NDZ-101) content were been examined. The results showed that the tensile modulusof elasticity increased from 1535.72MPa to 1670.92MPa, while the tensile strength decreased from 23.09MPa to 21.9MPa with the pine powder content from 30 shares to 60 shares (phr method ). The tensile modulus of elasticity rise from 1310.68MPa to 1398.23MPa, while the tensile strength decrease from 23.66MPa to 21.81MPa with the content of rice husk powder from 30 shares to 60 shares. Whether the pine powder or rice husk powder used as filler, the tensile elongation at break of the composites dropped slightly less than 1％, meanwhile pine powder size from 150 μm to 315μm did not affect the tensile strength of composites, all about in the vicinity of 24MPa. When the amount of titanate coupler was 1.5 (Phr method), the stretching integrated performance was best. With adding the same amount of pine powder or rice husk powder, rice husk powder / PVC composites are more plastic, but pine powder / PVC composites are more rigid.
