This paper deals with long fiber-reinforced composite strands using continuous ramie yarns, in which polypropylene including MA-PP (maleic anhydride-grafted polypropylene) was used as a matrix material. The composite strands were fabricated by a new method called multi-pin-assisted resin impregnation (M-PaRI) process, for which the equipment was newly applied after conventional extrusion process. The composite strands were then pelletized and injection molded. Tensile strength and Young's modulus of the resultant short ramie/PP reinforced composites were investigated. Results show that this new process improved the mechanical properties of injection-molded specimens
