Nonmetallic tendons with periodic SURFACE AND METHOD FOR MANUFACTURING nonmetallic tendons With periodic surfaces

摘要

1. The non-metallic reinforcing element with a periodic surface comprising interconnected strands of elongated mineral fibers impregnated with a polymeric binder, characterized in that the relief is in the form of pigtails three, six or nine high strength mineral fiber yarns, with a preliminary twist yarns or without and its diameter is determined by the formula D = d × n, where d - diameter of the filament, n - the number of filaments used in the manufacture of the reinforcing elementa.2. The non-metallic reinforcing element according to claim. 1, characterized in that the braid is woven from high strength fiberglass, basalt, carbon or aramid nitey.3. A method of manufacturing a non-metallic reinforcing element with a periodic surface, comprising placing and braiding together elongated mineral fiber filaments and impregnation of a polymeric binder, characterized in that the braiding is made of threads with a method pigtail arrangement angles to the longitudinal axis of the element within 10 ° -85 °, and impregnated reinforcing element is subjected to thermal polymerization, if necessary, and cooling.
