Analysis on Structural Reinforcement Effectiveness By Applying Fiber Sheet Manufactured By Stitch Bonding Method in Cool-roof Composites Waterproofing System

쿨루프 복합방수공법에서의 스티치본딩법 섬유시트 적용에 따른 구조적 보강 효과분석

In this study, we applied the fiber sheet made by the stitch bonding method, which is a structure in which transverse yarns and double yarns are crossed by applying the principle of sewing knitting without the use of adhesive, The tensile strength of the reinforced concrete structure was investigated. As a result of the tensile strength test of each specimen, the specimen to which the fiber sheet produced by the stitch bonding method was applied exhibited the highest tensile strength among the three types of specimens, and the fiber sheet produced by the needle punching method exhibited the lowest strength. In addition, the stitch - bonded fiber sheet showed a difference of strength of 0.1N / mm for both length and double - sided strength difference.
