漆籽壳纤维(LSSF)增强HDPE/UHMWPE复合材料摩擦学性能
Friction and wear properties of HDPE/UHMWPE compositesreinforced with lacquer seed shell fiber
摘要
Abstract
Lacquer seed shell fibers(LSSF) reinforced HDPE/UHMWPE composites were prepared by melt blending and injection molding technique.The effects of LSSF content on the fluidity and tribological properties of the materials were studied.The morphologies of wear surfaces were examined with the Scanning Electron Microscope (SEM).The results showed that the LSSF could greatly decrease the melt viscosity of the composites during processing, and increase the melt flow rate.The melt flow rate was improved 38.4 times compared to the HDPE/UHMWPE composites when the content of added fiber was 20 wt%.The friction coefficients of the composites were all lower than that of HDPE/UHMWPE composites, and the wear loss was decreased.The friction coefficient and wear volume were reduced by up to 60% and 72.9% by adding the fiber content of 15%.The SEM photographs of wear scars of composites clearly indicated that the abrasive wear and adhesive wear were the primary wear mechanisms.关键词
