Abstract: Methods of forming a composite structure include conforming at least one ply of material to a forming surface of a tool having differing features. Apparatuses for forming a composite structure include a forming tool and a material feed assembly configured to hold a supply of material, where the material feed assembly may be configured to pivot the supply of material relative to the forming tool. Composite structures having an at least partially annular shape are formed by an at least partially automated process.

Abstract: Automated methods of forming composite structures may include applying fibers having various predetermined lengths to a removable backing material to form a net shape or near net shape pattern for forming a composite structure having a varying transverse cross-section. Sheets of composite material may comprise strips of composite material adhered to a backing material in a net shape or near net shape pattern for forming a composite structure with a varying transverse cross-section. Further methods of manufacturing sheets of composite material may comprise applying fibers having various predetermined lengths to a removable backing material in a net shape or near net shape pattern for forming a composite structure having a varying transverse cross-section. Pattern preparation systems may include a material placement device programmed and configured to apply fibers having various predetermined lengths to a removable backing material. Forming systems may include an indicia locating device.
