Abstract: A method for fabricating a grid-stiffened structure from fiber-reinforced composite materials. A skin is applied to a smooth, hard base tool. Ribs comprised of carbon-fiber tows are formed on the skin, and shallow cavities are formed between the ribs and the skin. An expansion block is placed in each of the cavities, and is held in place by an elastomeric contact adhesive having adhesive properties that are substantially diminished when the adhesive is heated to an elevated curing temperature. The assembly is then autoclave cured. After cooling, the formed structure is separated from the base tool and the expansion blocks are removed from the cavities. A grid-stiffened sandwich structure is formed by applying an outer skin over the ribs and expansion blocks, before curing the assembly. After cooling, the outer skin is removed to allow extraction of the blocks, and subsequently bonded to the ribs.

Abstract: A gypsum board forming device (10) constitutes an apparatus of producing gypsum boards. A layered formation of a lower sheet (1), an upper sheet (2) and a gypsum slurry (6) passes through a forming gate (40). The forming device forms the formation into a plate-like configuration with use of upper and lower plates (20, 30). The upper plate (20) is constituted from a fixed substrate plate (21) and a movable plate (22), and the movable plate is in surface-to-surface contact with the upper sheet of the layered formation. A plurality of actuators (50) is supported by the substrate plate. Each of the actuators applies an upward or downward load (P) to the movable plate locally for a local deformation of the movable plate owing to a deflection thereof. A gate size (T) is locally changed by displacement of the movable plate relative to the substrate plate.
