      Materials that Vary in Their Morphology, Chemical Composition and Thermal 
      Stability.

AB  - In this study, four kinds of lignocellulosic fibers (LFs), namely, those from 
      Chinese fir (Cunninghamia lanceolata), Taiwan red pine (Pinus taiwanensis), 
      India-charcoal trema (Trema orientalis) and makino bamboo (Phyllostachys 
      makinoi), were selected as reinforcements and incorporated into high-density 
      polyethylene (HDPE) to manufacture wood-plastic composites (WPCs) by a flat 
      platen pressing process. In addition to comparing the differences in the 
      physico-mechanical properties of these composites, their chemical compositions 
      were evaluated and their thermal decomposition kinetics were analyzed to 
      investigate the effects of the lignocellulosic species on the properties of the 
      WPCs. The results showed that the WPC made with Chinese fir displayed a typical 
      M-shaped vertical density profile due to the high aspect ratio of its LFs, while 
      a flat vertical density profile was observed for the WPCs made with other LFs. 
      Thus, the WPC made with Chinese fir exhibited higher flexural properties and 
      lower internal bond strength (IB) than other WPCs. In addition, the Taiwan red 
      pine contained the lowest holocellulose content and the highest extractives and 
      alpha-cellulose contents, which gave the resulting WPC lower water absorption and 
      flexural properties. On the other hand, consistent with the flexural properties, 
      the results of thermal decomposition kinetic analysis showed that the activation 
      energy of the LFs at 10% of the conversion rate increased in the order of Taiwan 
      red pine (146(-)161 kJ/mol), makino bamboo (158(-)175 kJ/mol), India-charcoal trema 
      (185(-)194 kJ/mol) and Chinese fir (194(-)202 kJ/mol). These results indicate that 
      the morphology, chemical composition and thermal stability of the LFs can have a 
      substantial impact on the physico-mechanical properties of the resulting WPCs.
