Axial behavior of concrete confined with flax fiber-reinforced polymers

In recent years, the use of synthetic fiber-reinforced polymer (FRP) composites has gained significant popularity in structural engineering. The confinement concrete to improve its axial behavior been one most encountered applications such FRP materials. However, these materials are far from being friendly environment due their carbon release during production. Besides, high cost is still a major issue for applications, especially developing countries. Recently, research projects on composite made natural fibers have emerged specific fields, as automotive and aircraft industries, environmental policies. previous attempts using column mostly rely conventional woven fabrics fibers. this study, FRP’s which include unidirectionally aligned flax were used low-strength concrete. This material was either utilized alone or accompanied by glass hybrid form. results demonstrate that considerable increase strength ultimate strain capacity possible even specimens confined with only FRP. A higher enhancement forms.
