HYBRID LAMINATE COMPOSITE CURVE STRUCTURE AS CYLINDRICAL CONCRETE COLUMN REINFORCEMENT

Abstract

Composite materials are well known for their lightweight, easy to form, high elastic properties, and relatively low production costs. Laminated composites are composite materials that are widely applied in modern building structures such as aircraft walls, automotive cases, dashboards, press boards, etc. In this study, a curved laminated composite material was used as a reinforcing material surrounding the column structure. This study aims to analyze the mechanical strength of curved laminated composite materials as reinforcement for the cylindrical column concrete structure. Compressive testing of composite materials using the ASTM C39 standard. The materials used are jute fabric, e-glass, epoxy resin, and concrete aggregate. Specimens were molded using a vacuum bagging technique to minimize trapped air in the matrix. The curve shape of the laminated composite was obtained from the shape of the ASTM C39 concrete specimen with a diameter of 50 mm and a length of 150 mm. Based on the results of the study, the compressive strength of the structure increased up to 100% when the jute fabric was given up to 2 layers. Furthermore, the strength of the structure will increase up to 150% in the application of jute e-glass hybrid laminate composite.
