<p>Provided is a method of producing a composite plant fiber material capable of achieving both of a higher lightweight and better mechanical characteristics. A method of producing a composite plant fiber material having a structure wherein plant fibers (kenaf fibers, etc.) are bonded together via a thermoplastic resin (a polypropylene-based resin, etc.) and containing 30 to 95% by mass of the plant fibers referring the total amount of the plant fibers and the thermoplastic resin as to 100% by mass, which comprises, in this order, a spinning step for melt spinning a thermoplastic resin (a polypropylene-based resin) containing an acid-modified thermoplastic resin (maleic anhydride-modified polypropylene, etc.) to give thermoplastic resin fibers; a combining step for combining plant fibers (kenaf fibers, etc.) with the thermoplastic resin fibers to give a fiber mixture; and a heating step for melting the thermoplastic resin fibers in the fiber mixture.</p> |
