Abstract
Layers of composite material, such as pre-peg, may be deposited on a reconfigurable polymer mold. An array of actuated pins may deform the polymer mold into a desired 3D shape. The composite material may be inside a cavity formed by the mold and a flexible bag. A vacuum pump may remove air from the cavity, creating a partial vacuum. The partial vacuum may cause the flexible bag to press the composite tightly against the mold, so that the composite conforms to the desired 3D shape. One or more heating elements may be embedded in the mold and may heat the composite to cure the composite. Ball joints may connect the actuated pins to the polymer mold.
