Bending Behavior of Laminated Cementitious Composites Reinforced with Fiber Reinforced Polymeric Mesher (FRP) and Fibers

This paper describes the bending behavior of advanced laminated cementitious composites reinforced with FRP meshes embedded in a cement mortar matrix with or without discontinuous fibers. When fibers are added the term hybrid laminated composite is used. Three different types of meshes were used in combination with three different discontinuous fibers, two PVA fibers and one carbon fiber. The specimens were tested in four point bending. The loads and midspan deflections were measured. Equivalent elastic bending stress versus deflection curves were generated and representative curves were used to compare the first cracking strength, the post-cracking behavior, the maximum post-ctacking strength or modulus of rupture, the unidirectional cyclic behavior and the toughness indexes.
