Abstract: The recent research progress in the thermoplastic polymer/wood fiber composite was reviewed. Firstly, flame retardant mechanism of such composites was analyzed, subsequently the effects of non-halogen flame retardants such as inorganic, intumescent, nanoparticles, and composite systems on the flame retardancy and mechanical properties of the composites were summarized. At last, the developing trend of flame retardant thermoplastic polymer/wood fiber composite was pointed out.

Key words: thermoplastic polymer, wood fiber, composite, flame retardancy mechanism, non-halogen flame retardant
