AB  - In this study, a pulp beating machine was used to premix the pulp fibers with 
      high density polyethylene (HDPE) particles in water. The wet or pre-dried pulp 
      fiber/HDPE mixture was then melt-compounded by a twin screw extruder. For further 
      improving the dispersion of pulp fiber, some mixture was forced to pass through 
      the twin-screw extruder twice. The resulting mixture was compression molded to 
      the composite. The fiber distribution was observed by the aid of an optic and 
      scanning electron microscope. The mechanical and rheological properties and creep 
      resistance of the composites were characterized. Test results demonstrate that 
      when the wet pulp fiber/HDPE mixture was subjected to pre-pressing and oven 
      drying prior to extrusion compounding, the resulting composites exhibited 
      homogeneous fiber distribution, superior flexural property, creep-resistance, and 
      high storage modulus. Particularly, its flexural strength and modulus were 57% 
      and 222% higher, respectively, than that of the neat HDPE, while the composites 
      prepared without pre-dried were 19% and 100% higher, respectively. Drying the wet 
      mixture in advance is more effective than re-passing through the extruder for 
      improving the fiber dispersion and composite performance.
