The carbon fiber composite plate is finding their increasing importance as structural material in civil building, construction equipment, aviation and marine applications. Most often, reinforced concrete structures are strengthened due to internal reinforcement corrosion, freeze-thaw action or weak original design. The carbon fibers composite plate is used in strengthen and to improve the structure's load-bearing capacity, stiffness, and service life. But despite the good reinforcing properties of composite materi...

The objective of this paper to study the mechanical properties of natural fiber fabrics and to promote their use as a strengthening technique to reinforced concrete structures. The materials used are the natural hemp fibers and synthetic glass fibers as control material. The natural hemp fibers have been known since ancient times and remain relevant today. In fact, in civil engineering the use of composite carbon fiber material, although recent is an interesting alternative application in the field of strengthenin...

This paper describes an experimental analysis of damaged concrete corbel strengthened by gluing carbon fibre composite fabrics. The purpose of the investigation is to study all changes in behaviour and then their contribution to a better understanding of reinforced concrete corbel. Five reinforced concrete corbels are tested under tree-points bending to failure. Four of them are damaged at different load level up to 80% before strengthening. Test results show that strengthened corbel specimens using glue given an ...
