Abstract
In the manufacture of molded or laminated articles from composite materials such as fiber-reinforced and carbon or metal-loaded resins, the vacuum plastic bag or other air-tight barrier commonly used during the pressing, heating and curing phases is eliminated. Instead the various process cycles are conducted in one or more fluid-tight pressurizable chamber under various types of atmospheres to eliminate air pockets, vaporize and evacuate moisture and residual solvents, and suppress surface bubbling and frothing of pressed out fluids.
