Mechanical behaviour of aramid fiber reinforced polymer (AFRP) rebar/concrete interfaces

Aramid Fiber Reinforced Polymer (AFRP) rebars are being used as internal reinforcements of concrete structures for more than ten years. Their main advantages over common reinforcing steel rebars rely on their lightness, durability performances, mechanical properties, and electromagnetic neutrality. For this application, interfacial properties between the rebars and surrounding concrete play a major role on the mechanical performances of the reinforced concrete structure. In this context, this research aims at investigating the bond behaviour of commercially available AFRP rebars embedded in concrete. The first part of the paper is devoted to the assessment of mechanical and physical properties of the selected rebars. A second part is then dedicated to the study of interfacial properties between the rebars and concrete: the interfacial bond strength is first assessed using a specifically designed pull-out test, and a modelling of the interface behaviour is then developed, based on an analytic bond-slip law. The method used to identify key theoretical parameters of the model is also discussed.
