COMPOSITE LAMINATED MATERIAL AND ARTICLE MANUFACTURED FROM IT Russian patent published in 2002 - IPC

FIELD: structural materials used in mechanical engineering, aviation and space industry. SUBSTANCE: invention can be utilized in fabrication of power parts of airframe and in some other fields of technology where there are parts working in tension work. Proposed composite laminated material includes layers of aluminum alloy and layers of organic plastic based on binder with reinforcing filling agent produced from high-modular aramide fibers. In addition material has at least two aramide fibers with current-conductive coat which are located in layer of organic plastic or between layers of composite material. Aramide fiber with current-conductive coat utilized in material has resistance of 1000 Ohm as minimum. Reinforcing filling agent comes in the form of layers of cloth, unidirectional band or braided strap. Layers of aluminum alloy have perforated edges and electric insulation to bring out ends of aramide fibers with current-conductive coat to system of information collection and processing. Various articles can be produced from this composite laminated material. EFFECT: potential for control over stressed deformed state of material or articles made of it. 8 cl, 1 tbl
