AB  - The polymer water-lubricated bearing is widely used in marine transmission 
      systems, and the tribological properties can be improved by addition of inorganic 
      nano-fillers. The aim of this study is to investigate the effect of SCFs and 
      temperature on the water-lubricating properties of high-density polyethylene 
      (HDPE) composites. HDPE composites reinforced by varying content of short carbon 
      fibers (SCFs) were fabricated via twin-screw extrusion and injection molding 
      techniques to study the hardness and surface wettability of those composites. The 
      tribological properties under water-lubricated conditions were investigated 
      through a pin-on-disk reciprocating tribometer under different temperatures. The 
      results showed that the increase in hardness of HDPE composites reached maximum 
      to 42.9% after adding 25 wt % SCFs. The contact angle also increased with the 
      increase in SCFs content and reached a maximum of 95.2 degrees  as the amount of SCFs 
      increased to 20 wt %. The incorporation of SCFs increased the wear resistance and 
      lubricating property of HDPE composites at different temperatures. The HDPE 
      composite containing 20 wt % SCFs showed the lowest friction coefficient of 0.076 
      at 40  degrees C, and the wear track depth reached a maximum of 36.3 mm at 60  degrees C. Based 
      on the surface wetting property and wear analysis, potential effect mechanisms of 
      fillers and temperature were discussed. The knowledge from this study is useful 
      for designing the anti-wear water-lubricated polymer bearing.
