摘要： A composite component adapted to be formed into an aerofoil, a method of forming an aerofoil, an aerofoil, an aircraft wing and a forming jig. The method involves forming a flat layup sheet of plies (1) to be folded about a central leading edge region (6) of the layup into an aerofoil shape, applying to the flat layup (1) one or more layups of plies (9, 10) shaped as spars, partially curing the layup (1) with the spars attached, folding the resulting partially cured composite component (30) about the leading edge region (6) in a forming jig (19) so that opposing edges (4, 5) of the sheet meet as a trailing edge (36) of the aerofoil (35), clamping the jig (19) closed and curing the composite component (30) and adhesive in the forming jig (19) to form the finished aerofoil (35).

摘要： A system for fabrication of an aerospace structure incorporates a mold having a surface and at least one unidirectional SFL head adapted to lay down a plurality of collimated tows in a predetermined laminated pattern on the mold surface to produce a fuselage skin. At least one cross plied laminate SFL head is adapted to lay down a cross plied laminate base interface on the fuselage skin to establish a lattice rib shape for each of a plurality of lattice ribs. The cross plied laminate SFL head has a band placement head steerable to avoid structural design features and to maintain spacing from adjacent steered lattice ribs. The unidirectional SFL head is further adapted to lay down a plurality of collimated tows on the base interface of each of the plurality of lattice ribs for a first plurality of unidirectional tow plies in each lattice rib. The unidirectional SFL head has a fiber placement head steerable to match the lattice rib shape to avoid structural design features and to maintain spacing from adjacent steered lattice ribs.

摘要： Systems and methods are provided for bi-directional cutters for Automated Fiber Placement (AFP) machines. One embodiment includes a bi-directional cutter for Automated Fiber Placement (AFP) manufacturing. The cutter includes a cutter body that has an upper edge and a lower edge, and has an opening placed between the upper edge and the lower edge that is dimensioned to enable passage of a tow of fiber through the cutter body. The cutter also includes a first blade disposed on the lower edge of the cutter body that is oriented to cut the tow when the cutter is driven downward, and a second blade disposed on an edge of the opening in the cutter body that is oriented to cut the tow when the cutter is driven upward.

摘要： A compaction device for use with an automated fiber placement machine includes multiple compaction rollers mounted for independent displacement on a supporting frame. The attitude of the compaction rollers change relative to each other when fiber tows are laid up at an angle over an edge of a tool in order to maintain compaction pressure on the tows and thereby reduce non-compacted areas of the tows.

摘要： A pressure bulkhead for a pressurized vehicle such as an aircraft employs a plurality of layers of composite fiber material having uni-directional fibers arranged in a single direction within the composite fiber material. The pressure bulkhead incorporates non-traditional radial and circumferential stiffening members into a composite laminate and aligns the radial stiffening members with the direction of dominant load paths. The radial and circumferential stiffening members are interlaid between full layers of the composite fiber material. Related methods of manufacturing the pressure bulkhead include using automated fiber placement equipment to form each layer of the pressure bulkhead and discretely orient the integral stiffeners and the uni-directional fibers in each layer.

摘要： To provide a method of manufacturing a shaft-shape composite member in which a bent section is suitably treated. A plurality of thermosetting fiber-reinforced resin materials made of a UD material is supplied to a bending section of a mold in a state of being aligned in parallel to an axial direction of a cavity to form a UD material layer. Subsequently, after forming a tubular member having the UD material layer by the metal mold, by thermally curing the tubular member, the shaft-shape composite member having the bent section can be obtained. When manufacturing the shaft-shape composite member, a cross-section orthogonal to the axial direction of each of the fiber-reinforced resin materials has a circular shape.

摘要： A system (100) for additively manufacturing a composite part (102) comprises a delivery assembly (266), a feed mechanism (104), and a source (116) of curing energy (118). The delivery assembly (266) comprises a delivery guide (112) movable relative to a surface (114) and is configured to deposit a continuous flexible line (106) along a print path (122). The delivery assembly (266) further comprises a first inlet (170), configured to receive a non-resin component (108), and a second inlet (250), configured to receive a photopolymer resin (252). The delivery assembly (266) applies the photopolymer resin (252) to the non-resin component (108). The feed mechanism (104) pushes the continuous flexible line (106) out of the delivery guide (112). The source (116) of the curing energy (118) delivers the curing energy (118) to a portion (124) of the continuous flexible line (106) after it exits the delivery guide (112).
