巻付け、第2図(0)の(b)に示すように積層する。In the second step (B), a film adhesive 2 is applied to the step surface of the joint member 1, and after drying, the adhesive 2 is fully precured to maintain the adhesive layer thickness. This preliminary curing is carried out to make the thickness of the adhesive layer uniform, and is carried out under heating and pressurizing conditions within a range that does not interfere with the final curing in the next step [FIG. 2(C)]. For example, the heating temperature should be set to a minimum temperature of 80°C or higher at which the adhesive flows, and a maximum temperature of 125°C or lower, which is necessary to slow down the crosslinking reaction rate, and the pressure is set to the minimum pressure necessary to obtain a uniform thickness and edges. 5 An upper limit pressure cuff that does not make the adhesive layer thickness too thin when the pressure is 1 ps or more. It is preferably 0 psi or less. Next, the above-mentioned joint member 1 is subjected to a mold release treatment as shown in FIG. 2 (0) (a). Composite material molding material 4'f! is attached to the finished mandrel 5, and a molding material wrapping device (not shown) is used to wrap the composite material molding material 4'f! :
It is wound and laminated as shown in FIG. 2(0)(b).
