Evaluation of Hybrid Reinforcement (Fiber-Reinforced-Plastic Rod with Steel Core)
The corrosion of concrete reinforcement is a problem that seriously affects structures exposed to harsh environments (parking garages, marine structures, chemical plants, etc.). Currently the most popular method of corrosion protection is epoxy-coating for steel rebars and tendons. As an alternative to epoxy-coating, this project presents an initial evaluation of hybrid reinforcement. Hybrid reinforcement consists of a FRP (fiber-reinforced-plastic) skin with a steel core. The FRP skin (fully-bonded) is made of braided, epoxy-impregnated aramid or vinylon fiber. Besides protecting the steel core from corrosion, the FRP skin provides a structural function. Hybrid reinforcement allows specifying a reinforcement behavior by changing the core-to-skin crosssectional ratios and by combining different core and skin materials. Uniaxial tensile test results are presented to show the characteristics of different hybrid rods. Results from beams reinforced with hybrid rods are presented to demonstrate the flexural behavior of concrete members reinforced with hybrid rods.
