Abstract text:
This paper presents the set-up of an experimental study which focuses on the behavior of carbon fiber reinforced polymer (CFRP) composite strips, adhesively bonded to steel surfaces. For that purpose, single lap shear pull-off specimens were designed and prepared. The experimental program consists of a wide range of combinations between three types of CFRP strips (with normal, medium and high modulus of elasticity) and two types of adhesives, each of them being applied in three thicknesses (1 mm, 2 mm and 3 mm). For each combination, three identical specimens were prepared. Important aspects regarding the behavior of CFRP-to-steel bonded joints, such as: identification of the failure modes, characterization of the bond-slip behavior of the interfaces, checking the validity of the effective bond length can be obtained and analyzed by performing the envisaged experimental program based on the proposed set up.
