    Abstract: The present invention relates to a process for the manufacture of short or discontinuous lignocellulosic fiber in combination with synthetic fiber filled thermoplastic composites, in which the process consists of preferably, defiberization and dispersion of the cellulosic fibers in the thermoplastic matrix, further consolidation and dispersion of the blended thermoplastic composition, further blending of the same with inorganic fibers to get the moldable thermoplastic composition and further injection or compression or compression injection molded under high pressure ranging from 100 tones to 1000 tones and a temperature range from 170 to 210 degree centigrade into composite products. The said composites have a tensile strength of at least 75 MPa and a flexural strength of at least 125 MPa. The invention also relates to the use of the said composites in automotive, aerospace, furniture and other structural applications.
