STEERING WHEEL AND ITS PREPARATION

摘要

PURPOSE:To obtain a light wt. steering wheel having not only vibration resistance but also high strength and excellent torsional rigidity, by orienting a resin impregnated fiber bundle comprising continuous fibers in the axial direction of each part to form a skeketal and subsequently winding the resin impregnated fiber bundle around the skeletal at a predetermined angle to the axial direction of each part. CONSTITUTION:A line of a resin impregnated fiber bundle comprising continuous fibers are wound around the mold of a steering wheel predetermined times to form a skeletal 11 and a separate resin impregnated fiber bundle 12 comprising continuous fibers is wound around the skeletal 11 at a proper angle theta to the axial direction of a spoke part to form a steering wheel made of continuous fiber FRP. It is desirable to select the angle theta in a range of 30-60 deg.. By this constitution, the torsional rigidity of the spoke part is markedly enhanced as compared with such a case that the resin impregnated fiber bundle comprising continuous fiber is oriented only to the axial direction (direction wherein the angle theta is 0 deg.) of the spoke part.
