摘要： 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.

摘要： A continuous filament additive manufacturing machine for building a part by laying down a continuous mono-filament or composite filament material layer by layer on a tool or substrate. The machine includes a system, such as a robot, operable to move in at least three degrees of freedom, and a placement module coupled to the system and being configured to deposit the continuous filament material. The placement module includes a guide for guiding the material to the part, a heat source for pre-heating the material as it is being deposited from the placement module and a compaction device for compacting the material as it is being deposited from the placement module. The compaction device includes an ultrasonic horn that is ultrasonically vibrated to melt or flow the material and cause the material to fuse and be compacted to the tool or substrate.

摘要： 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.

The machine includes a system operable to move in at least three degrees of freedom, and a placement module coupled to the system and being configured to deposit the continuous filament material. The placement module includes a guide for guiding the material to the part and an ultrasonic compaction device for compacting the material as it is being deposited from the placement module. The compaction device includes an ultrasonic driver, an attachment member and a plurality of ultrasonic horns independently coupled to the attachment member and being movable independent of each other. The plurality of ultrasonic horns are ultrasonically vibrated to melt or flow the material and cause the material to fuse and be compacted to the tool or substrate.
