The aim of this study is to experimentally investigate the influence of epoxy resin treatment on the tribological properties of various natural fibers (NF) reinforced plant-derived polyamide 1010 (PA1010) biomass composites. Five types of NFs, namely hemp fiber, jute fiber, ramie fiber, sisal fiber and flax fiber were used as reinforcement fibers. Various NFs were surface-treated by three steps of surface treatment: (a) alkaline treatment by sodium chlorite (NaClO2) solution, (b) surface treatment by ureidosilane coupling agent (A-1160) and (c) surface treatment by epoxy resin (EP) solution. These biomass composites were extruded using a twin screw extruder and injection-molded. Tribological properties by ring-on-plate type sliding wear testing were evaluated. It was found that epoxy resin treatment has stronger influence on the tribological properties of various NF/PA1010 biomass composites, although the improvement effect on the tribological properties showed different tendencies according to the type of NFs. In particular, the combinations of NaClO2, A-1160 and EP were the most effective surface treatment for enhancing the wear properties of NF/PA1010 biomass composites. These may be attributed to the change in the mode of wear mechanisms according to type of NFs with surface treatment by epoxy resin.
