Wood-rubber composite fabricated from rubber mixing and vulcanization molding process

Min Xu, Lina Han, Sheldon Qiang Shi, Jian Li

Abstract


Wood-rubber composites (WRC) has been successfully manufactured through rubber mixing and vulcanization molding process. The morphological properties of the composite panels were characterized using a scanning electron microscope (SEM). It showed that the wood powders were well embedded in the tire rubber matrix. The functional groups of the composites were observed by Fourier transform infrared spectroscopy. The curing characteristics were analyzed on the WRC fabricated with different wood powder loadings. The mechanical properties of the WRCS including, tensile strength, elongation at break, hardness and rebound resilience, were examined. It was determined that the wood powder loading should not be more than 50 wt %. Incorporation of wood powder increased the hardness of the WRC with about 53% improvement when the wood powder loaiding increased from 0% to 50%. The water absorption of the WRC was lower than that of traditional wood-based composites.
