Creep and wear properties of four different types of husk fibers/polyvinyl chloride composites

Four kinds of husk fibers, coconut shell, hazelnut shell, walnut shell and rice husk were used as filler material and polyvinyl chloride as the base material to prepare the husk fiber/polyvinyl chloride composites. Four kinds of husk fibers were analyzed by comprehensive thermal analyzer and FTIR. The creep and wear properties of four kinds of husk fiber/polyvinyl chloride composites were tested. The results show that the cellulose content in rice husk is 43.6%, which is the highest in the four kinds of husk fibers. The rice husk fiber/polyvinyl chloride composites have good interface and mechanical properties, and their compressive, tensile and flexural strength are the highest, which is 43.1 MPa, 23.2 MPa and 46.1 MPa, and increase by 13.7%, 33.3% and 21.0%, respectively, compared with walnut shell fiber/polyvinyl chloride composites of lowest strength. Under the same stress, the creep strain of rice husk fiber/polyvinyl chloride composites is the smallest. Under the same wear conditions, the specific wear rate of rice husk fiber/polyvinyl chloride composites is the smallest, while their friction coefficient is also the smallest.
