Abstract: PURPOSE: A polypropylene composite material is provided to have excellent tensile strength, flexural strength, impact strength, etc by using environment-friendly natural fiber as filler, thereby acceptable for vehicle interior/exterior material, etc. CONSTITUTION: A polypropylene composite material composition comprises 20-97 weight% of polypropylene, and 3-80 weight% of nanokenaf of which fiber diameter is 100nm - 100micron. The polypropylene is a homopolymer, a random copolymer, a block copolymer, or mixtures thereof. The composition additionally comprises 1-10 weight% of compatibilizing agent. The compatibilizing agent is one or more kinds selected from maleic anhydride-grafted polypropylene, silane coupling agent, and resin.
