REINFORCED ELASTOMER PANEL Russian patent published in 1996 - IPC

FIELD: design of aircraft, propeller, river and seagoing ships, conveyer belts, hingeless doors and gates of refrigerating and vacuum chambers, transported floors, forms, heat-protective coatings, etc. SUBSTANCE: panel has framework formed by flexible and rigid members, cells and honeycombs or corrugations and elastomer porous filler connected with walls. Framework is made of chain of four rigidly connected or articulated cells. Axes of hinges connecting the cells are located normally to center surface of panel. Space of framework between cells is filled with telescopic tubes, honeycombs or corrugations rigidly connected with them; their walls are thickened but for bending sections forming the flexible hinge. Elastomer filler is perforated over entire height of walls of framework. Outer layer of filler of panel is made of prestretched elastomer film. Cell of framework consists of four rigid members. Two members form central pair; they are connected over their edges by two pairs of flexible members - parallel bearing walls. Two rigid members of cell are secured by their edges in center portion of flexible members; they are located in tandem in plane of symmetry of cell. Each pair of parallel flexible members of cell may be combined in one rigid beam. Axes of hinges of beams are located at normal to center surface of panel. EFFECT: enhanced efficiency. 3 cl, 8 dwg
