Abstract: A system for processing a workpiece includes a constraining container, a pressure-triggered coupling, and an expandable medium. The constraining container includes an interior volume and is configured to enclose at least a portion of the workpiece to be processed. The pressure-triggered coupling is configured to secure the constraining container in a closed configuration and is configured to release the constraining container upon an interior pressure of the interior volume of the constraining container reaching a trigger pressure. The expandable medium is configured to be disposed within the interior volume between at least a portion of the constraining container and at least a portion of the workpiece and is configured to expand such that the expandable medium applies a positive pressure to the constraining container and the workpiece.

Abstract: A method for bonding materials includes steps of: (1) enclosing at least a portion of a first material and a second material within an interior volume of a constraining container; (2) expanding an expandable medium disposed within the interior volume; (3) applying a positive pressure to the constraining container and at least one of the first material and the second material in response to expanding the expandable medium; and (4) bonding the first material and the second material together.
