Twenty double-lap shear tests are set up to evaluate the bond properties of interfaces uniaxial Carbon Fiber Reinforced Polymer (CFRP) strips as overlays on unreinforced masonry wall prisms. The efficient use of the material significantly depends on the bond between the externally bonded sheet and the substrate material since a premature debonding of the objects involved may lead to a premature failure of the system and, thus, to a low degree of exploitation of the fibrous structure. In the test both the length and the width of the CFRP sheets are considered in order to analyse the mechanical behaviour of the specimens changing those parameters. In the first part of the research the background of the test and the materials used for the experimental campaign are presented while the second part is more focused on the technical procedure of the double-lap shear tests setting up. The results obtained with these experiments are then plotted to have a full understanding of the behaviour of the materials used in this specific scenario.
