LAMINATED MATERIAL

FIELD: electric insulating and sealing materials designed for operation in various electrical is subject to variable thermal and mechanical loads. SUBSTANCE: laminated material includes two and more parallel layers of polymer composite containing polymeric matrix and fillers particles including solid and fibrous. In this case, for each line of material orthogonal section at maximum operating compression, the sum of lengths of sections by the line of fillers particles is less than thickness of laminated material by value larger than sum of elongations of fillers particles along this line at maximum operating heating of material. The sum of lengths of sections by this line of fillers particles for each layer is smaller than thickness of this layer by value larger than sum of elongations of fillers particles within corresponding layer along this line at maximum operating heating of material. In each layer of material, particles of solid fillers and fibrous fillers (filler) are located along layer length so that the sum of lengths of sections of particles along each line of material sections in plane of layers with consideration of total heat elongation of particles along these lines is smaller the length of respective lines of section within this layer. The given features make it possible to increase functional potentialities of laminated materials due to reduced possible separation into layers caused by nonuniform heat expansion. EFFECT: higher efficiency of use. 1 dwg
