MIRROR Russian patent published in 1998 - IPC

FIELD: cosmonautics, military technology, communication systems, laser systems, information and adaptive optics. SUBSTANCE: mirror includes plate- backing made from composite carbon-carbon material with reinforcing frame produced from carbon FIBRE of three-dimensional spatial orientation and pyrocarbon matrix with volumetric proportion of fibre to pyrocarbon equal to (0.6-0.4):(0.4-0.6). Reinforcing frame is formed by laying of one or several packages of layers (sheets) of carbon cloth so that threads of wrap of any two contacting layers ( sheets ) of cloth in lay of frame form angle equal to 180 deg: n, where n is number of layers of cloth in package and ≤ and by their broach in vertical direction with uniform stepping till volumetric proportion of fibres in horizontal and vertical directions is achieved. Mirror also has separating layer made from polycrystalline silicon and reflecting layer formed on surface of separating layer. EFFECT: expanded application field. 1 cl, 4 dwg
