Abstract
Wood powder as reinforcing fillers and polyethylene as a matrix have been used for wood plastic composites (WPC). In preparing WPC, the coupling agent, phthalic anhydride(PA) was used in order to increase the interfacial bonding force between matrix and fillers. In this study, the effect of wood powder, PA concentration on the mechanical properties and interfacial phenomena on the composites was evaluated. The tensile strength of 3 wt% PA-treated composites reached its maximum value of 25.91 MPa when the wood powder content was 30 wt%, and the maximum impact strength of PA-treated composites was 46.24 J/m. SEM observation showed that wood powder was well dispersed and bonded well with PE matrix by increasing the coupling agent concentration.

목분 충진제의 함량을 달리 하고 PE 수지를 매트릭스로 하여 wood plastic composites (WPC)를 제조하였다. 또한 매트릭스와 충진제간의 계면결합력을 증가시키기 위하여 커플링제로 phthalic anhydride(PA)를 사용하였으며, 충진제의 충진률과 커플링제 처리가 복합재의 기계적 물성에 미치는 영향과 계면현상을 관찰하였다. 목분의 충진률 30 wt%, PA커플링제농도 3 wt%일 때 인장강도는 26.37 MPa로 최대값을 나타내었으며, 이때 충격강도는 46.24 J/m의 최대값을 나타냈다. 또한 WPC는 주사전자현미경 관찰을 통해서 커플링제의 처리농도의 증가에 따라 목분과 PE 수지와의 분산과 결합이 잘 이루어졌음을 확인할 수 있었다.
