AB  - The flame retardancy of wood-polymer composites significantly affects their 
      potential applications. Thus, multilayered wood flour/high-density polyethylene 
      (HDPE)/polycarbonate (PC) composites were prepared via thermocompression to 
      improve the fire retardancy of wood-polymer composites in this paper. Thermal 
      degradation behavior, flame retardancy, and flexural strengths of the resulting 
      composites were investigated using a thermogravimetric analysis, cone 
      calorimetry, and mechanical testing machine, respectively. Results revealed that 
      the boric acid treatment reduced the heat release rate and total heat release of 
      the wood flour/HDPE composites and increased their mass of residues. However, 
      boric acid reduced the flexural strength of the resulting composites. The 
      combustion test indicated that PC cap layers suppressed the combustion of the 
      resulting composites via the formation of carbon layers. Adding PC layers reduced 
      heat release and increased the flexural strength of the resulting composites. 
      Finally, the failure mode of the multilayered wood flour/HDPE/PC composites in 
      the three-point flexural test was simulated by finite element analysis.
