      Polyethylene Composites.

AB  - Rice husk ash (RHA)-reinforced composites are now used in many tribological 
      applications. We prepared two kinds of RHAs using different pretreatment and the 
      same pyrolysis process, namely water-treated RHA (WRHA) and acid-treated RHA 
      (ARHA). Comparing the two RHAs, the RHA pretreated with hydrochloric acid (HCl) 
      was found to have a smaller particle size and a more uniform dispersion. 
      Accordingly, the two kinds of RHAs were used as fillers and added to the 
      high-density polyethylene (HDPE) matrix by an extrusion process. The results 
      showed that the friction coefficient (COF) value of the composites with ARHA was 
      reduced to 0.12 when an additional amount of 0.75 wt.% or 1.5 wt.%. WRHA was used 
      as a filler to the amount of 1.5 wt.%, but the COF value was raised to about 
      0.21. The reason for this phenomenon may be due to its larger particle size and 
      more severe abrasive wear. This work provides a method for making natural biomass 
      fillers that can effectively reduce the COF of HDPE composites with slight 
      decreases in mechanical properties.
