ROUND FIBER-REINFORCED PLASTIC WIRE, PROCESS FOR PRODUCING THE SAME, AND FIBER-REINFORCED SHEET

摘要

A round fiber-reinforced plastic wire that realizes lifting of restrictions on molding speed and on the number of wires produced once, nonuse of any mold release agent, avoiding of post-molding roughening and other work, attaining of substantial cutback of production cost and attaining of substantial improvement of product quality; a process for producing the round fiber-reinforced plastic wire; and a relevant fiber-reinforced sheet. The process for producing a round fiber-reinforced plastic wire comprises the steps of (a) continuously feeding, while twisting, reinforcing fiber bundle (f1) composed of unidirectionally aligned multiple reinforcing fibers; (b) impregnating the continuously fed reinforcing fiber bundle (f1) with matrix resin (R); and (c) heating the resin impregnated reinforcing fiber bundle (f2) while applying a tension of given intensity so as to provide the reinforcing fiber bundle with a circular cross section and harden the resin, so that fiber-reinforced plastic wire (2) with a circular cross section is obtained.
