Abstract
Methods, a consumable assembly, and a tool for preparing a composite structure from a laminate disposed on a surface of a mold. The method involves preparing consumable materials, such as a breather sheet and a vacuum bag, and preparing an inflatable tool, outside of the mold. These prepared consumable materials and the inflatable tool are then inserted into the mold, and the inflatable tool is inserted into a folded assembly of the breather and vacuum bag. Once inserted into the mold, the inflatable tool is inflated, which deploys the consumable materials against the laminate. A vacuum can be generated, which maintains the deployed consumable materials against the laminate. This can be done for many hours. Finally, the laminate is cured inside the mold so as to form the composite structure.
