Abstract
A composite manufacturing system for aircraft structures is provided. The composite manufacturing system comprises a tool for forming a composite structure, a vacuum bag, and a tool base. The tool comprises cured composite planks and layers of flexible material. The cured composite planks run parallel to each other. The layers of flexible material are positioned between and bonded to the cured composite planks. The vacuum bag surrounds the tool and is configured to apply pressure to the tool during curing of the composite structure. The tool is configured to deform in response to the pressure and prevent poor quality laminate and/or anomalies from developing in the composite structure during curing. The tool base is configured to hold the tool in place as it deforms.
