<p>An improved method for forming an assembly of laminated materials is provided. The method eliminates a necessity to evacuate a package or position the assembly in an autoclave for forming. In the method, the assembly (14) is positioned against the die face of a rigid die (12). A cavity of essentially constant volume is formed about the die and assembly and encloses the side of the assembly opposite that in contact with the rigid die. The cavity is filled with expandable spheroids (56). The spheroids are expanded to provide the necessary force acting on the assembly to urge the assembly against the rigid die to form the completed assembly. Preferably, the expandable spheroids (56) are thermally expandable and can comprise, for example, silicone rubber having a coefficient of thermal expansion of about 50 x 10-5 inches per inch per degree Fahrenheit.</p> |
