Three dimensional (3D) TRC (Textile Reinforced Concrete) composite is a relatively new composite material consisting of cement-based matrix reinforced with 3D fabric. The goal of this work was to study the flexural behaviour of cement-based composite reinforced with 3D warp knitted fabrics. Hybrid 3D fabrics made of variable content of glass and polypropylene (PP) yarns were investigated as well as the influence of impregnating the 3D fabrics in epoxy. The epoxy impregnated fabrics were composed of glass yarns (x, y directions) with aramid and polyester (PES) yarns as spacers (z direction). Two conditions of epoxy were tested wet and dry. It was found that impregnating the 3D fabric in epoxy highly improved the composite performance in terms of strength, displacement and toughness, the improvement was more significant when the epoxy was at wet stage. The 3D hybrid fabric composites were showing greater flexural strength and toughness but lower displacements with increase in glass yarns content and decrease in PP yarns content. This study clearly shows the high potential and benefit of using 3D fabrics as reinforcement for cement-based composites.
