After tying the bundle of strong yarns to form a knot (3), the thermosetting resin (2) is cured by impregnating the thermosetting resin (2) in the bundle of high-strength yarns formed at a predetermined interval along the longitudinal direction as described above. A high strength yarn molded body for rebar replacement is manufactured.

본 발명에 따른 고강력원사 성형체는 염분 등에 의한 내부식성이 우수하고, 중량이 가벼우면서도 기계적 물성이 뛰어나고, 길이방향을 따라 일정간격으로 매듭이 형성되어 설치작업이 용이하다.High-strength yarn molded body according to the present invention is excellent in corrosion resistance due to salt, etc., light weight and excellent mechanical properties, knots are formed at regular intervals along the longitudinal direction, easy installation work.
