Tensile properties of hybrid rods for concrete reinforcement
AbstractThis paper presents an initial evaluation of hybrid reinforcement for prestressed and non-prestressed concrete members. A hybrid rod consists of an frp (Fibre-Reinforced-Plastic) skin with a steel core. The frp skin is made of braided, epoxy-impregnated aramid or vinylon fibre. Besides protecting the steel core from corrosion, the frp skin provides a structural function. Hybrid reinforcement behaviour may be customized by changing the core-to-skin cross-section ratio and by combining different constituent materials. Tensile tests have shown that changing the frp skin material, frp skin thickness, steel core diameter, and steel core yield strength resulted in various stress-strain behaviours. The tensile stress-strain curves of the hybrid rods displayed a bilinear nature. It was demonstrated that the law of mixtures can be used to predict the stress-strain behaviour of the hybrid rods.
