Composite structures and methods of forming composite structures may include at least one ply of material extending along a length of the composite structure. The at least one ply of material includes sections of material extending along the length of the composite structure.
Claims13
A composite structure comprising:
- at least one ply of material extending along a length of the composite structure, the at least one ply of material comprising:
- sections of material extending along the length of the composite structure that has been applied to a tool with a stretchable removable backing material, each of the sections comprising fibers in at least one selected orientation relative to the length of the composite structure, the at least one selected orientation comprising a non-zero degree angle fiber orientation, wherein at least some of the fibers have been stretched over the tool with force applied to the stretchable removable backing material by a forming head of a composite structure forming device.
A composite structure comprising:
- at least one ply of material extending along a length of the composite structure, the at least one ply of material comprising:
- sections of material extending along the length of the composite structure, each of the sections comprising fibers in at least one selected orientation relative to the length of the composite structure, the at least one selected orientation comprising a non-zero degree angle fiber orientation, the sections of material of the at least one ply of material comprising individual sections that have been cut from a common feedstock, reoriented and positioned on a continuous stretchable removable backing material to provide the at least one selected orientation of the fibers, and lined up end to end to define a length of the at least one ply of material, wherein at least some of the fibers have been stretched over a tool with a forming head of a composite structure forming device.
