METHOD FOR MANUFACTURING STRAIN-RESISTIVE SENSOR MADE IN FORM OF A WOVEN FABRIC FROM CONDUCTIVE CARBON FIBERS AND DIELECTRIC FIBERS Russian patent published in 2023 - IPC G01L1/22 B82Y30/00 

FIELD: sensor technology.

SUBSTANCE: invention can be used to control processes occurring in critical products in the aerospace industry. A method for manufacturing a strain-resistive sensor made in form of a woven fabric of conductive carbon fibers and dielectric fibers that provide insulation for the latter is proposed. The assembly and installation of the strain-resistive sensor is carried out during the manufacture of the product, placing parts of the product on each other, represented by pre-woven layers of a conductive fabric, an insulating fabric and a newly conductive fabric, ensuring the mutually perpendicular direction of carbon fibers in the conductive fabrics, then the final assembly of the product is carried out and subsequent joint impregnation of the product and the piezoresistive sensor with ceramic slip or resin mixed with a crosslinking agent, followed by annealing.

EFFECT: possibility of registering mechanical loads inside the product, which allows to track the processes occurring in it and predict product failures.
