摘要： A composite and method for producing the composite by incorporating wood or wood pulp fibres with a suitable thermoplastic polymer and coupling agent are described. Homogeneous, void-free transparent/translucent thermoplastic materials in the form of pellets, films or three-dimensional moldable products are produced. The wood pulp fibres can be discrete natural fibres, and flexible assemblies of nano to micro elements, e.g., assemblies of aggregated carbon nanotubes. It is also possible to use our vacuum-assisted co-extrusion process to produce hybrid composites comprising the wood pulp fibre and a further rigid fibre, like glass or carbon fibres, and a flexible fibre or fibrillar network, like cellulose fibres or cellulose filaments. The thermoplastic resin can be, but not limited to, polyolefins, like polypropylene or polyethylene, or polyesters, like polylactic acid, or co-polymers, like acrylonitrile-butadiene-styrene terpolymer.
