To reduce the weight and thickness, and improve rigidity, durability and air permeability by making triaxial woven fabric reinforced plastic into a sheet shaped molding.
For example, a triaxial woven fabric 1 with a weave density of about 18.2 is woven by a bundle of about 6000 carbon fibers with a tensile strength of about 3609 kgf/mm2 and a tensile elastic modulus of about 23500 kgf/mm2. The triaxial woven fabric 1 is impregnated with a resin component composed of an epoxy resin to form a pre-preg 2. The pre-preg 2 is fixed along the cylindrical wood pattern with a diameter of about 150 mm, bent and put in a hot blast stove to be hardened. After cooling, the triaxial woven fabric reinforced plastic molding is formed by cutting. By this arrangement, the molding having excellent bending rigidity, METSUKE, air permeability, application feeling, and indicating performance can be obtained.
