To provide a method for producing a rod-shaped structural material for a vehicle in which a thermoplastic resin material sufficiently penetrates into and is integrated with a reinforced fiber material to exhibit sufficient strength.SOLUTION: A method for producing a rod-shaped structural material Sc for a vehicle, in which carbon fibers Fb are impregnated and integrated with a polypropylene (PP) resin. Under the method, non-flat bundled carbon fibers Fb are allowed to pass into a storage tank 2 in which a liquid thermoplastic resin material has been stored, and the non-flat bundled carbon fibers Fb passing through are pressed into a flattened state in the storage tank 2 to spread in order for the PP resin to penetrate between the carbon fibers Fb, and the flattened carbon fibers Fb into which the PP resin has penetrated are converged and molded into a non-flattened bundle again.SELECTED DRAWING: Figure 4

    【課題】熱可塑性樹脂材が強化繊維材内に十分に浸透してこれと一体化し十分な強度を発揮する車両用棒状構造材の製造方法を提供する。【解決手段】カーボン繊維Fb内にポリプロピレン(PP)樹脂が含浸されて一体化した車両用棒状構造材Scを製造する方法であって、液状の熱可塑性樹脂材が貯留された貯留槽2内に非扁平な束状のカーボン繊維Fbを通過させるとともに、通過する非扁平な束状のカーボン繊維Fbを貯留槽2内で扁平状態に圧し拡げてカーボン繊維Fb間にPP樹脂を浸透させ、PP樹脂が浸透した扁平なカーボン繊維Fbを再び非扁平な束状に収束成形する。【選択図】 図4
