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.
