Composite Tape Placement Backing Plate Force Reaction

The patent merges the formation of composite stiffeners and composite panels into a single integrated manufacturing process. The tape placement machine deposits continuous composite tape that forms both the panel and stiffeners simultaneously, eliminating the need to separately form and assemble stiffeners. This integration resolves the contradiction by achieving both manufacturing simplicity and structural consistency through a unified deposition process.

The patent uses preliminary action by positioning a backing plate in advance at the location where stiffeners will be formed. The backing plate is positioned before the composite tape deposition begins, providing a pre-prepared surface that guides the tape placement machine to automatically form stiffeners with correct geometry and positioning. This preliminary preparation enables consistent stiffener formation without complex post-assembly operations.

The patent combines multiple manufacturing operations into a single automated tape placement process. The machine continuously deposits composite tape that simultaneously forms both the panel and stiffener components, eliminating the sequential steps of separately manufacturing stiffeners, transporting them, and assembling them onto the panel. This merging of operations directly increases productivity while maintaining design adaptability.

The patent implements continuous useful action through the automated tape placement machine that continuously deposits composite tape without interruption. The process maintains continuous motion from the tape supply through the deposition head to the forming stiffeners and panel, eliminating idle time between separate manufacturing operations. This continuity maximizes productivity while the programmable nature of the machine preserves adaptability for different designs.

The patent introduces a backing plate as an intermediary element between the tape placement machine and the composite structure being formed. The backing plate serves as a mediating surface that receives the placement force from the machine, preventing direct application of force that could cause inconsistencies. The backing plate is positioned to provide support exactly where stiffeners are being formed, acting as a buffer that maintains dimensional accuracy while allowing automated deposition to proceed.

The patent applies preliminary anti-action by positioning the backing plate in advance to counteract the placement force before it can cause inconsistencies. The backing plate is pre-positioned at the stiffener formation location to provide opposing support that neutralizes the potentially harmful effects of the tape placement machine's deposition force. This preliminary counter-measure ensures consistent stiffener geometry is achieved throughout the automated process.
