A B S T R A C T Novel composite thermoplastic materials reinforced with "hemp fibers" and exhibiting high impact and tensile strengths, high bending modulus and heat distortion temperatures are obtained by first admixing hemp fibers such as remie, flax, jute, hemp, manila hemp or sisal hemp with ligneous fibers such as wood chips or wood particles to form a uniform admixture, and then adding to this admixture thermoplastic matrix such as polypropylene or polyethylene and thoroughly mixing all the constituents to cause hemp fibers and ligneous fillers to be evenly dispersed in the matrix thereby forming a mass of particulate agglomerate, which can be then formed into sheeting for stamping processes or pellets for injection or transfer molding processes.
