    Abstract: The present invention relates to a process for the manufacture of structural hybrid thermoplastic composites where organic and inorganic fibers are well dispersed in a thermoplastic matrix. The process comprises defibrillating the organic fibers with or without the presence of surface active agents using a mixer at a high shear and at a temperature lower than the decomposition temperature of organic fibers and melting point of the surface active agents to separate the hydrogen bonded fibers and generate microfibers, followed by blending and dispersion of the organic fibers in the thermoplastic matrix to produce a fiber composite, followed by further blending and dispersion of the fiber composite with inorganic fibers at a low shear to get the moldable hybrid composite, followed by extrusion, injection or compression-injection molding. Low shear mixing maintains the inorganic fiber length. The process produces high performance composite materials having excellent performance properties and are ideally suited for automotive, aerospace, furniture, sports articles, upholstery and other structural and semi-structural applications.
