FIELD: mechanical engineering; aircraft industry; railroad construction; production of lamellar products of the constructional designation. ^ SUBSTANCE: the invention is pertaining to production of lamellar products of the constructional designation containing mainly glass fibers and may be used in various branches of industry, for example, in mechanical engineering and aircraft industry as a material of load-bearing panels, and also in building of railroads as a material of straps of rails butts insulating bonds. The lamellar hardware product contains the interleaving with each other impregnated with a binder layers of a skeleton glass-fiber cloth and the glass fiber strands of a roving. The maximum retention of strength of the constructional composite hardware products, in which holes are made as well as simplification of the method of production of a hardware product is achieved due to a pairwise connection with the help of a thread and a needle by a broaching method of layers of the strands of a roving and the skeleton glass-fiber cloth. ^ EFFECT: the invention ensures maximum retention of strength of the constructional composite hardware products and simplification of the method of their production of a hardware product. ^ 2 cl, 1 dwg |
