REPAIR PATCH, METHOD FOR MOLDING REPAIR PATCH, AND METHOD FOR REPAIRING COMPOSITE MATERIAL
A repair patch is for a composite material to repair a part to be repaired which is a repair target of the composite material. The patch includes a patch main body that is formed by laminating a plurality of fiber reinforced preforms in a thickness direction, and has a bonding surface to be bonded to the part to be repaired; and a removal layer that is provided on the bonding surface to be peelable off from the patch main body. The bonding surface includes an inclined surface that is inclined with respect to the thickness direction of the patch main body. The removal layer includes a processed portion that causes the removal layer to have a shape complementary to a shape of the inclined surface of the patch main body
METHOD FOR MANUFACTURING HIGH-PRESSURE TANK AND HIGH-PRESSURE TANK
A method for manufacturing a high-pressure tank includes: forming a preform by winding a carbon fiber around a liner to form a fiber layer on an outer periphery of the liner; and impregnating the fiber layer of the preform with a curable resin and curing the curable resin. When winding the carbon fiber around the liner, a metal wire together with the carbon fiber is wound around the liner.

Also disclosed herein are methods for shaping a composite material that include the use of isolated composite materials. For example, disclosed is a method for mechanical thermoforming of a composite material to form a shaped composite material.
CONSTRUCTION OF TUBULAR ASSEMBLIES
A method and apparatus for constructing a tubular assembly 40 comprising an inner portion (24) and a further portion (23) surrounding the inner portion. The inner portion (24) comprises reinforcement (37) and the further portion (23) being formed from a strip (50) of material comprising two opposed longitudinal marginal side portions (53). The apparatus comprises an assembly station (220) comprising a wall (253). The apparatus comprises means for advancing the inner portion (21) along a first path (231) extending passed the wall (253), and means for advancing the strip (50) along a second path (232) and causing the strip to encircle the wall (253) and thereby wrap about and surround the inner portion (21). The apparatus further comprises means (321) for introducing resinous binder into the reinforcement (37) as the strip (50) is being wrapped about the inner portion (21).
FIBRE FLATTENING
A method of forming a fibre article, comprising: providing a former having a contoured forming surface; locating a fibre preform between a first diaphragm and a second diaphragm, the second diaphragm being offset from the forming surface; drawing a vacuum between the first and second diaphragms so as to hold the preform captive between the diaphragms; displacing the second diaphragm towards the former so as to bring the second diaphragm into partial contact with the former; drawing a vacuum between the second diaphragm and the former so as to bring at least a part of the second diaphragm adjoining the preform into conformity with the forming surface; and setting the preform in its configuration; wherein: the fibre preform comprises one or more substantially inextensible fibres extending linearly in a first direction; the forming surface comprises a concavity and prominences on either side of the concavity; and the step of bringing the second diaphragm into partial contact with the former comprises bringing the second diaphragm into contact with the prominences whilst the second diaphragm does not fully contact the concavity and with the substantially inextensible fibres extending from one of the prominences to the other.
MOLDING SYSTEM AND METHODS FOR FORMING STRUCTURES
A molding system and methods of forming a structure are presented. The molding system is configured to sequentially form features of a structure. The molding system comprises a first tool comprising a number of features configured to completely form a first set of radii of a structure and a number of partial forming features configured to partially form a second set of radii of the structure, and a second tool comprising a number of completion features configured to complete shaping of the second set of radii.
INTEGRATED PICK, PLACE, AND FORMING APPARATUS AND METHOD FOR COMPOSITE CHARGES OVER COMPLEX GEOMETRIES
An apparatus for picking, placing, and forming a composite charge over a complex geometry tool comprises a first frame, a second frame, and a plurality of dynamic mechanisms. The first frame is formed from rigid material and includes a first frame member that forms at least a rectangular perimeter. The second frame is formed from flexible material and includes a second frame member that forms at least a rectangular perimeter. Each dynamic mechanism is connected to the first frame and the second frame and located along the perimeters of the first frame and the second frame. Each dynamic mechanism includes a length-variable component positioned between the first frame and the second frame, with at least a portion of the dynamic mechanisms configured to vary a length of the length-variable component for the second frame member to conform to the shape of the complex geometry tool.
