摘要: A method for preparing a composite material that includes the steps of: (i) heat treating natural lignocellulosic fibers at a temperature of 130 to 320° C. for 2 minutes to 24 hours in an atmosphere oxygen-deficient in and in the presence of water vapor, and (ii) mixing the heat treated natural lignocellulosic fibers with at least one thermoplastic polymer in the molten state and whose melting point is less than or equal to 230° C. The method is useful for producing vehicle parts from a composite material having natural lignocellulosic fibers with reduced volatile organic compound odor emissions.
