<p>A method of manufacturing a long-fiber-reinforced resin structure comprises the steps of immersing an actually-endless long-fiber bundle in a molten resin bath, opening the long fibers while passing the bundle between pairs of opening pins arranged on both sides of the long fiber bundle, without contacting with the long fibers and impregnating the bundle with a resin. Columnar-shaped bodies can be manufactured by cutting the long-fiber-reinforced resin structure into sections of predetermined lengths. The long-fiber-reinforced resin structure can be manufactured by an opened-fibers resin impregnating apparatus which includes a long-fiber bundle inlet in an end wall on the upstream side of a region where a predetermined amount of molten resin is stored and made to flow, or in a top plate provided on the upstream side of the region, at least one pair of opening pins arranged at specified intervals substantially in a vertical direction in such a manner that a long-fiber bundle is dipped and passed contactlessly, a shaped nozzle for passing the introduced long-fiber bundle between the paired opening pins without contacting them with the pairs, and a mechanism for drawing in the long-fiber reinforced resin structure.</p> |
