Method and apparatus for consolidating a workpiece at elevated temperature

Abstract

A consolidation apparatus includes a female mold having a first portion and a second portion, a movable caul plate within the first portion of the female mold, and a pressure bladder disposed between the caul plate and the second portion of the female mold. A pressurization line communicates between the interior of the pressure bladder and a gas source exterior to the female mold, and an evacuation line communicating between the unfilled space between the caul plate and the second portion, and a vacuum source exterior to the female mold. In using the apparatus, a workpiece is loaded into the first portion of the female mold between the caul plate and the first portion. The consolidation apparatus and the workpiece contained therein are heated, a pressure is applied to the pressurization line, and a vacuum is simultaneously applied to the evacuation line.
