EXPERIMENTAL INVESTIGATION OF THE TENSILE STRENGTH OF THE HYBRID FIBRESREINFORCED POLYMER (FRP)

Fibre-reinforced polymer (FRP) has been widely used for strengthening and repairing of concrete structures which can enhance the flexural strength, fatigue strength and the durability of the concrete structures. Among other types of FRP, Glass FRP (GFRP) is seen as an affordable material compared to carbon or aramid fibres. However, the low modulus of elasticity of GFRP obstructs their widespread use in construction applications. In order to enhance the mechanical properties of GFRP, this study incorporates GFRP with carbon fibre-reinforced polymer (CFRP) in a single polymer matrix. Two approaches were followed to fabricate hybrid bars with different characteristics. The fabricated hybrid bars were tested under axial tensile loading test. The obtained results show that the new hybrid bars have higher tensile strength compared by the conventional GFRP
