Embodiments of the invention are directed toward extractable tooling devices for composite structure manufacturing. An extractable tool, according to some embodiments of the invention, can include a rigid core, one or more foam blocks, an elastic membrane, and a nozzle. The foam blocks can be shaped to provide a mold of the composite structure being manufactured. This mold may require the extractable tool to be trapped by the composite structure after manufacture. Use of the foams can allow the extractable tool to shrink in at least one dimension in order to extract the tool from the trapped configuration.
