Study on the carbon fiber reinforced plastics(CFRP) rebars for concrete structure
Abstract
The use of fiber reinforced plastics(FRP) rebars to replace steel rebars has emerged as one of the many techniques put forward to enhance the corrosion resistance of reinforced concrete structures. In particular, FRP rebar offers great potential for use in reinforced concrete construction under conditions in which conventional steel-reinforced concrete has yielded unacceptable service.
The study described is a part of an experimental plan on the application of carbon fiber reinforced plastics(CFRP) reinforcement for concrete structures. Results of experimental study on rebar manufactured with three different types of carbon fiber reinforced plastics are presented and compared to these properties. This paper also attempts to present the properties of CFRP rebar manufactured with three different types and its components compared to foreign CFRP rebar.
As a result, It was found that the properties of CFRP rebar depend largely on the curing time, temperature and fiber volume fraction. Finally, it was found that bending strength and interfacial shear strength of the developed domestic CFRP rebar is similar to those of foreign CFRP rebar.
