問題点を有していた。(Problems to be Solved by the Invention) However, the above-described conventional method for manufacturing an FRP steering wheel core material had the following problems.

た。 First, the continuous long fibers F are rolled into the winding groove 10 of the winding die 10.
The ring part 2 and the boss part 3 formed by winding around a and the boss metal fitting 14 are formed by winding the laminated fiber bundle between the continuously supplied fibers, the groove peripheral surface, and the metal fitting outer peripheral surface, so that the appearance and density of the ring part 2 and boss part 3 are improved. Although it is stable, the winding direction of the laminated fiber bundle of the spoke part 4 is changed by the notch groove 10b and the guide pins 15, 15, and the laminated fiber bundle of the spoke part 4 stretched in the space is not tightly converged or constant. , and because the fiber volume content (Vf value) is low,
Bending as a steering wheel after the resin hardens,
The problem was that the strength characteristics such as torsion were unstable, and the shape and dimensions of the product were not constant.

り、強度特性も弱くなるという問題点があつた。 In addition, when impregnating the continuous long fibers F with a synthetic resin or winding them around the winding die 10 to form a laminated fiber bundle, air is trapped in the single fibers of the spoke portion 4 or between the laminated fibers. As a result, after the resin hardens, it becomes a structure containing air bubbles, resulting in a problem in that when it is commercialized as a core material, the air bubbles become brittle and its strength properties are also weakened.

The manufacturing method for the steering wheel core material is characterized by the following: After the continuously supplied resin-impregnated long fibers are wound into a winding mold to form the ring, spoke, and boss portions of the steering wheel core material, The winding mold is released from the rotating main shaft, the main shaft is extended in the direction of the boss part to apply tension to the laminated fiber bundle of the spoke part, and the spoke part is restrained by a tightening jig, and then The core material is left in an atmosphere where the resin impregnated into the fibers is cured, so that the resin of the core material is cured.

高くなる。(Function) Since the FRP steering wheel core material is manufactured through the above process, the fixation between the winding mold and the main shaft is released, the main shaft is extended in the direction of the boss part, and the spoke part is laminated. By applying tension to the fiber bundle, the fiber directions of the laminated fiber bundle can be aligned. In this state, by tightening and fixing the spoke portion with a tightening jig, excess resin can be removed, increasing the volume content (Vf value) of the fibers.

Therefore, after curing, the strength characteristics such as bending and torsion, shape, dimensions, etc. of the steering wheel can be stabilized.

硬化させることを特徴とする繊維強化樹脂製ステ
アリングホイール芯材の製造方法。1. After winding the continuously supplied resin-impregnated long fibers into a winding mold to form a ring part, a spoke part, and a boss part of the steering wheel core material in layers, the ring part winding jig of the winding mold is Release the fixation between the tool and the main shaft, extend the main shaft in the direction of the boss part to apply tension to the laminated fiber bundle of the spoke part, tighten and fix the spoke part with a tightening jig, and then A method for producing a steering wheel core material made of fiber-reinforced resin, characterized in that the core material is then left in an atmosphere where the resin impregnated into the fibers is cured, thereby curing the resin.
