A method for the manufacture of a fiber reinforced plastic structure, comprising the steps of winding a continuous long-staple fiber impregnated with a liquid resin around a plurality of winding jigs until the resultant bundle of resin impregnated fibers attains a predetermined thickness; setting rings tightly in place on the linear portions of the resin impregnated fiber bundle between the jigs; and moving the tightly set rings relative to the linear portions thereby wringing the resin impregnated fiber bundle and expelling bubbles entrapped within the fiber bundle.

Method for production of fiber reinforced plastic structure

A process for preparing a fiber reinforced plastic structure having points of branching, which comprises the steps of, positioning pins at points of branching in the structure and repeatedly hanging and repeatedly stretching a resin-impregnated strand of continuous long-staple fibers over and between said pins, thereby completing the structure of the points of branching.

Process for preparing a fiber-reinforced plastic structure having

A steering wheel made of resin, wherein a reinforcement, as a core of the steering wheel, consists of reinforcing members corresponding to a ring part, a sub-ring part and spoke parts, which are formed of windings and by hardening of a strand of continuously long fiber impregnated with a resin for hardening, after being wound onto the ring part, the sub-ring part and the spoke parts via a boss and spacers which are disposed at the joints between the ring part, the sub-ring part and the spoke parts.

Steering wheel

A method for joining a fiber-reinforced plastic structure to a metallic insert for fitting around a rotary shaft is disclosed. The method comprises winding a resin-impregnated strand of continuous long-staple fibers around an engaging means formed on the metallic insert thereby effecting the desired union. By this method, a rotatable element such as a wheel, a hand-wheel or the like, such as a steering wheel can be produced.

Method for joining a fiber-reinforced plastic structure

A method for the manufacture of a fiber reinforced resin structure having branched portions comprising, winding a long continuous resin impregnated fiber strand repeatedly on a molding jig having a predetermined structure, winding said fiber strand tightly around each of the branched portions of the structure, and hardening said resin.
