Abstract

Wood flour was used as a reinforcing filler for high-density polyethylene (HDPE). Different fibre treatments were carried out to improve the bonding at the polymer-fibre interface. Wood flour composites coated with alkoxy-silane coupling agents (silane A-172 and A-174) generally showed higher tensile strength and modulus values. A significant improvement in tensile properties was achieved with the addition of polymethylenepolyphenyl isocyanate. The Izod impact strength of the composites decreased with an increase in filler concentration.
