Abstract: A collapsible, open cell void filler (2) is made by stacking a series of paper core sheets (58) and gluing the core sheets to one another at appropriate points (56) to create a generally hexagonal open cell core structure when expanded. The stack (60) of core sheets is cut along a series of cutting planes (62) to create rows of independently expandable hexagonal cells (16). The end cells (20) of each row are connected to one another by an outer sheet (18) to create a core slab (68). When the outer sheets are separated, the rows of cells expand from their collapsed, reduced volume condition to their expanded, increased volume condition. As the cells expand they separate laterally from one another along the cutting planes. This eliminates deformation of the cells and permits the full extension of the rows of cells. Deck sheets (6) can be fastened to the outer sheets so that when the core slab is expanded, the deck sheets lie adjacent the open cell ends (28).

Abstract: A process for making a honeycomb sandwich panel in a single furnace cycle which is particularly applicable to making a glass honeycomb sandwich panel as might be utilized in the construction of a glass mirror substrate. In one embodiment, lengths of glass tubing are sandwiched between glass faceplates. On heating to softening temperature, the faceplates are compressed between rigid plates until they are sealed against the open tube ends. Then the sealed tubes are inflated, or the external gas pressure decreased, so the tubes expand and seal also against each other. At the same time the softened faceplates are pressed against and conform to the shape of the rigid restraining plates. One way to achieve inflation of the tubes is with a gas manifold communicating through a hole in the back faceplate and into each tube. A pressure differential is maintained while the glass is cooled until it becomes rigid.
