Abstract
PURPOSE: To obtain a fiber reinforced plastic coil spring which is of an uniform quality and has a high fiber content, by a method wherein a fiber bundle impregnated with resins is rolled round a spiral groove in an inner mold, and the resins excessively impregnated in the fiber bundle is then squeezed out as an outer mold is screwed in.
CONSTITUTION: A coil-molding spiral groove 6 and a screw thread 7 for screwing-in of an outer mold, which is positioned in the middle of the adjoining grooves and at equal-pitched spaces, are provided in an inner mold 5, and a coil-molding spiral groove 9 and a screw groove 10 are also made in an outer mold 8. A resin-impregnated fiber bundle, whose diameter is larger than that of the coil-molding spiral groove, is rolled round the spiral groove of the inner mold. The spiral groove at a portion where to shart screwing-in is tapered for facilitating the entry of the fiber bundle into the spiral-groove, and resins excessively impregnated in the fiber bundle is squeezed out as the outer mold is screwed in along the screw thread 7. The formation of said fiber bundle applicable to the subject coil spring is preferably such that reinforcing fiber, such as carbon fibers, polyamide fibers, etc., which has a high strength and modulus of elasticity, is wound around a core 1 to a desired outer diameter so that layers 2, which have a winding angle of θ against an axial direction, are formed at intervals of one layer, and layers 3, which have a winding angle of 180-θ, are also formed at one-layer intervals.
