ABSTRACT:
A method for producing a fiber reinforced plastic rod having ribs on its surface by impregnating a reinforcing material which has continuous long fiber bundles with an uncured liquid resin. A rib forming member is separately prepared by impregnating a fiber bundle reinforcing material with an uncured liquid resin. A fiber reinforced plastic rod is formed by helically applying the rib forming member to the surface of the substrate forming member and together curing the two members into an integral body. A fiber reinforced plastic rod, prepared in accordance with this method, is also described.
