ABSTRACT The present invention resides in an ultra-drawn polyethylene fiber reinforced composite material having the ultra-drawn polyethylene fibers as the reinforcement material and the epoxy resin as the matrix resin, wherein the epoxy resin is modified with an elastomer to improve adhesivity with the ultra-drawn polyethylene fibers. Such improvement in adhesivity is ascribable to that low polarity portions are formed in the epoxy resin by introducing the elastomer to raise affinity with ultra-drawn polyethylene fibers, and that the low polarity portions are formed into domains with a specific shape according to types of elastomer employed to effect intercation by a shape effect with the surface micro- structure of the fibers.
