Potential use of different kinds of carbon in production of decayed wood plastic composite

Abstract

This study investigated the mechanical, chemical structure and thermal properties of hot press molded wood plastic composite (WPC) panels produced from different amounts (30, 40, or 50% weight) of decayed Pinus massoniana Lamb. and polypropylene with chitosan (3 wt%) and different kind of carbon (2 wt%). The results were compared with the properties of WPC produced without carbon. The mechanical, chemical structure and thermal data showed that WPC with carbon was better than WPC without carbon, and the best condition to produce decayed wood plastic composite was hot pressing temperature at 170 °C for12 min, Carbon Nanotubes (CNT) and chitosan (CS) accounting for 2% and 3% of total mass, and the proportion of decayed wood and PVC is 40% and 60%.
