TEXTILE FABRIC FOR STRUCTURAL MATERIAL Russian patent published in 2020 - IPC D03D15/00 

FIELD: textile industry.

SUBSTANCE: invention relates to textile industry, in particular to the field of creation of textile fabrics with specified technical characteristics, used as fillers of composite materials for high-technology industries (wind power engineering, shipbuilding, aviation, automotive industry, etc.). Textile fabric includes four layers of continuous parallelized threads laid with possibility of maintaining their initial physical and mechanical properties. Threads of outer layers of linear density of 1,200 tex are laid at angles of 0° and 90° in relation to longitudinal axis with density of 6–8 threads/inch, and threads of inner layers of linear density of 300 tex are laid at angles of +45° and -45° in relation to longitudinal axis with density of 10–13 threads/inch. Two inner layers are interconnected by piercings from synthetic threads, and all four layers are additionally stitched with same threads.

EFFECT: increased specific breaking load of threads, reduced value of deflection of composite material and increased value of destructive stress at interlayer shift of composite material, in which textile fabric is used as reinforcing filler.
