Assessing the embedded length of epoxy-bonded carbon laminates by pull-out bending tests

Abstract

To evaluate the embedded length of epoxy-bonded fibre carbon laminates into concrete, pull-out bending tests were carried out. The laminates were embedded into concrete in order to prevent the phe-nomenon of peeling and to add extra protection against fire, therefore mobilising the potential of reinforce-ment of this composite material, with high tensile strength and stiffness. The bond-slip relationship obtained at the concrete-laminate interface can be used to define the corresponding constitutive law. This work de-scribes the tests that were performed, and discusses the results obtained in the preliminary experimental pro-gram carried out.
