发明名称 METHOD OF FABRICATING CELLULAR STRUCTURES
摘要 A method of making cellular, honeycomb-like structures by utilizing cooperating mandrels and rams to deform and shape relatively collapsible material into a cellular array. The material is suitably secured to retain the tensioned state produced by the cooperation of the mandrels and rams, and a plurality of the structural members thus formed is stacked, and a perimetrical frame is attached to the outermost walls of the cells of the outermost structural members. The frame maintains the tensioned state of the cellular array, so that the mandrels can be removed from the array. Various sizes and configurations of rams and mandrels may be used to provide cellular arrays of different or composite configurations.
