Material Characterization of Hybrid FRP Bars

Abstract

Hybrid fiber-reinforced polymer (FRP) rebar has emerged as one of the most promising and affordable solutions to the brittle failure problems of ordinary FRP rebar in concrete structures. Hybrid FRP comprised of two or more fibers with a single or several matrix which leads to a desirable combination of performance and environmental attributes. In this study, two type of fibers namely carbon fiber and glass fiber embedded in epoxy resin were used for manufacturing of hybrid FRP bars by hand lay-up process. This chapter deals with history of FRP materials, need for hybrid FRP and experimental tests carried out for tensile strength properties of hybrid FRP bars.
