Pass the filament 12 through a tank 15 filled with
After coating the surface of the filament 12 with the thermosetting resin 14, the filament 12 is reciprocated in the axial direction by the reciprocating mechanism 17 in synchronization with the mandrel 10 rotated by the motor 16, and as shown in FIGS.
As shown in the figure, the filament 12 is wound around the outer peripheral surface of the mandrel 10 in a series in a substantially radial and intersecting manner while applying tension until a predetermined thickness is reached.
