Development of the Green Composite Consists of Woodchips, Bamboo Fibers and Biodegradable
From the viewpoint of the effective utilization of natural resources, the green composite which is produced by solidifying woodchips has been developed. However, since this composite was solidified by the compressive load without the binder, the composite was very brittle and had no water resistance . In this study, to improve these defects, the biodegradable resin is used as an adhesive and bamboo fibers are used as reinforced fibers. By using woodchips with two kinds of the particle size, bamboo fibers with three kinds of the length and a biodegradable adhesive, several kinds of specimens changed those mixing ratio were produced. The composite consists of the ingredients which are friendly to the environment. By the four-point bending test and Charpy impact test, the bending strength and impact strength of the composites were examined. From the experimental results, it was found that the high bending strength and high energy absorption were obtained in case where woodchips with the small particle size and long bamboo fibers were used. The proposed composite has the high strength, and the practical application is also possible.
