筒体１とフランジ部２を硬化する。 First, as shown in FIG. 3, the resin-impregnated unidirectional fiber 5 is wound using a mandrel 4 filament finding machine. Next, as shown in FIG. 4, the receiving mold 7 is attached to the lower end 6 of the mandrel 4
Fit and secure with bolt 8. Thereafter, as shown in FIG. 5, the cylindrical portion 3 of the resin-impregnated interwoven fiber 9 having an L-shaped cross section is inserted into the cylindrical body 1, and the flange portion 2 is brought into contact with the surface of the receiving mold 7. Next, as shown in FIG. 6, a disc-shaped silicone rubber 10 as shown in FIG. 7, which has a large volumetric expansion when heated, is applied to the outer peripheral surface of the cylindrical portion 3 so as to pressurize the back surface of the flange portion 2. A compressible silicone rubber 11 is attached to the concave portion 13 of the holding mold 12, and this mold 12 is superimposed on the receiving mold 7 and fixed with bolts 14. Finally, the cylindrical body 1 and the flange portion 2 are hardened by heating in a heating furnace (not shown) in the state shown in FIG.

により圧縮力をコントロールできる効果がある。 As described above, according to the present invention, a silicone rubber member is interposed between the inner surface of the presser mold and at least the flange portion, and heat molding is performed after the presser mold is overlapped with the receiving mold. The thermal expansion force of the rubber member can be used as pressure force for molding, which prevents damage to the flange compared to direct pressure in a mold, and also has the effect of controlling compression force by adjusting the temperature. be.
