Abstract
This study investigated the effects of simulated soil aging on the thermal and wear properties of rice husk fiber/polyvinyl chloride (PVC) composites reinforced with three inorganic fibers (aluminum silicate fiber (AS); basalt fiber (BF) and zirconia fiber (ZF)). The thermal and wear behavior of the composites exhibited a downward trend during the simulated soil aging process; weak interface (pulling out of fiber) resulted in the induction of strength and anti-aging properties. However, the addition of inorganic fibers improved the anti-aging properties of the composites. When the simulated soil aging time was up to 21 d, ZF reinforced composites (ZFRC) exhibited high thermal and wear resistance properties due to superior interfacial adhesion between the fiber and PVC matrix. The average friction coefficient (μ) and specific wear rate (K) of ZFRC were reduced by 12.1% and 40.7%, respectively, compared to the unreinforced composites.
