Abstract: A vacuum bag system (VBS) for forming pre-consolidated composite blanks hasa blank enclosure for sealing around a periphery of the blank, while leaving a second sideof the blank exposed, an articulated forming caul (AFC) with at least two facets, eachfacet effectively jointedly coupled to an adjacent facet, and having a respective,independently controlled, heater integrated with, or coupled to the facet. The VBS furtherhas a forming enclosure for sealing around a periphery of a tool. The blank enclosurebrings the blank and the facets into uniform thermal contact resistance and mechanicalcontact; and permits the articulated AFC to distribute thermal and mechanical load acrossthe blank during forming, even as the facets move to align to faces of the mold.
