AB  - The purpose of this study is to compare the characteristics of wood-plastic 
      composites (WPCs) made of polypropylene (PP) and wood fibers (WFs) from discarded 
      stems, branches, and roots of pomelo trees. The results show that the WPCs made 
      of 30-60 mesh WFs from stems have better physical, flexural, and tensile 
      properties than other WPCs. However, the flexural strengths of all WPCs are not 
      only comparable to those of commercial wood-PP composites but also meet the 
      strength requirements of the Chinese National Standard for exterior WPCs. In 
      addition, the color change of WPCs that contained branch WFs was lower than that 
      of WPCs that contained stem or root WFs during the initial stage of the 
      accelerated weathering test, but the surface color parameters of all WPCs were 
      very similar after 500 h of xenon arc accelerated weathering. Scanning electron 
      microscope (SEM) micrographs showed many cracks on the surfaces of WPCs after 
      accelerated weathering for 500 h, but their flexural modulus of rupture (MOR) and 
      modulus of elasticity (MOE) values did not differ significantly during 
      weathering. Thus, all the discarded parts of pomelo trees can be used to 
      manufacture WPCs, and there were no significant differences in their weathering 
      properties during 500 h of xenon arc accelerated weathering.
