| Abstract: | This paper presents the results of a study that was conducted on the sliding behavior of a carbon-fiber-reinforced polymer rod in contact with copper or aluminum sleeves simulating the components of a wedge anchor system. The influence of sandblasting the metal sleeves was related to the displacement and shear stress of the couple for different contact pressures. In general, the interfacial shear stress was found to increase linearly with contact pressure. However, the highest interfacial shear stresses were recorded when sandblasted soft annealed sleeves were used. This effect was the result of a larger contact area which increased the strength of the interface. |
