Abstract
A unitary reflector system and methods for forming that include a reflector and support structure. These two structures can form a single unitary structure. Such a reflector system can be constructed from composite laminate materials that are laid up or formed in during a single manufacturing process. The composite support structure can be formed on the back of the reflector using standard laminate techniques. An extractable tool, can include a rigid core, one or more foam blocks, which may be shape a memory polymer foam, 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. E
