B33Y 30/00 - ADDITIVE MANUFACTURING, i.e. MANUFACTURING OF THREE-DIMENSIONAL [3D] OBJECTS BY ADDITIVE DEPOSITION, ADDITIVE AGGLOMERATION OR ADDITIVE LAYERING, e.g. BY 3D PRINTING, STEREOLITHOGRAPHY OR SELECTIVE LASER SINTERING - Details thereof or accessories therefor
A method is disclosed for additively manufacturing a composite structure. The method may include directing a continuous reinforcement into a print head, and coating the continuous reinforcement with a first matrix component inside of the print head. The method may further include coating the continuous reinforcement with a second matrix component, discharging the continuous reinforcement through a nozzle of the print head, and moving the print head in multiple dimensions during the discharging. The first and second matrix components interact to cause hardening of a matrix around the continuous reinforcement.

F41H 1/02 - Armoured or projectile- or missile-resistant garments; Composite protection fabrics
A vehicle body may have a skeleton formed by a plurality of overlapping layers bonded to each other. Each of the plurality of overlapping layers may be fabricated from a continuous fiber coated with a matrix material. A trajectory of the continuous fiber may be different between adjacent layers of the plurality of overlapping layers.

B29C 70/52 - Pultrusion, i.e. forming and compressing by continuously pulling through a die
B32B 3/26 - Layered products essentially comprising a layer with external or internal discontinuities or unevennesses, or a layer of non-planar form; Layered products essentially having particular features of form characterised by a layer with cavities or internal voids
B32B 5/12 - Layered products characterised by the non-homogeneity or physical structure of a layer characterised by structural features of a layer comprising fibres or filaments characterised by the relative arrangement of fibres or filaments of adjacent layers
B32B 5/28 - Layered products characterised by the non-homogeneity or physical structure of a layer characterised by the presence of two or more layers which comprise fibres, filaments, granules, or powder, or are foamed or specifically porous one layer being a fibrous or filamentary layer impregnated with or embedded in a plastic substance
A system is disclosed for use in additively manufacturing a composite structure. The system may include a matrix reservoir, and a fiber guide configured to separately receive a plurality of matrix-wetted reinforcements from the matrix reservoir. The system may also include a die configured to receive the plurality of matrix-wetted reinforcements from the fiber guide and to cause the plurality of matrix-wetted reinforcements to converge into a ribbon. The system may additionally include a cure enhancer configured to cure the matrix in the composite material during discharge of the ribbon from the die, and a support configured to move the die in multiple dimensions during discharge of the ribbon.
A system is disclosed for use in additively manufacturing a structure. The system may include an additive manufacturing machine, a memory having computer-executable instructions stored thereon, and a processor. The processor may be configured to execute the computer-executable instructions to cause the additive manufacturing machine to discharge a path of composite material, and to make a determination regarding existence of support located at a side of the path of composite material. The processor may be further configured to execute the computer-executable instructions to selectively cause the additive manufacturing machine to compact the path of composite material after discharge with a variable pressure that is based on the determination.
