To provide a filament winding apparatus that prevents a fiber bundle supplied to a liner from interfering with other fiber bundles and fiber supplying guide. A first guide unit 43 and a second guide unit 44 including a plurality of fiber supplying guides 80A and 80B arranged radially and moving in a direction approximately perpendicular to a central axis Ra of a liner 1, a driving unit 60 configured to change a radial position of the fiber supplying guides 80A and 80B, and a controller C configured to control the driving unit 60 are provided. When a fiber bundle F supplied from the fiber supplying guide 80A crosses between the fiber supplying guide 80B and the liner 1, the controller C makes the distance from the fiber supplying guide 80B to the central axis Ra of the liner 1 larger than the distance from the fiber supplying guide 80A to the central axis Ra of the liner 1, and in the reverse case, the controller makes the distance from the fiber supplying guide 80A to the central axis Ra of the liner 1 larger than the distance from the fiber supplying guide 80B to the central axis Ra of the liner 1.

The present invention is a method for producing a pressure vessel comprising impregnating a fiber material with a photocurable resin composition comprising a vinyl ester resin (A), a urethane (meth)acrylate resin (B), and a photoinitiator (C), winding the fiber material around the outer surface of a hollow vessel, and then irradiating light having a wavelength in the visible region and/or the ultraviolet region at an irradiance of 9 mW/cm 2 or more. With the method for producing a pressure vessel a pressure vessel having excellent balance among impact resistance, strength, and heat resistance can be rapidly produced.

The invention relates to a method for producing an endless belt (10) which has at least one fiber (13) that circulates in a spiral manner in the endless belt (10). In the method, a circular support film (11) is provided which has one side that is provided with an adhesive layer (12), and the at least one fiber (13) is applied onto the support film side provided with the adhesive layer (12) in a spiral manner. The invention further relates to an endless belt produced according to the aforementioned method.

Embodiments refer generally to systems and methods for manufacturing a cylindrical spar tube (120) of the sort that might be used in a horizontal stabilizer (108) for a helicopter (100). An exemplary method may comprise laying out onto a flat surface (220, 420) (and possibly stacking) plies (201, 202, 203, 301, 302, 303, P001-P004) of composite material, rolling the material (424, 624, 852) onto a mandrel while applying pressure and curing the rolled material.
