RESUMO

An experimental study on the bond between carbon fiber fabric composites and concrete is described in this work. This experimental program consisted of tension-compression tests of specimens with two concrete blocks (movable and fixed) jointed by carbon fiber fabric strips bonded on two opposite sides of these blocks. Nine specimens, with three concrete compressive strength of 20,5MPa , 28,7MPa and 38,1MPa at 28 days and two fabric width of 50 mm and 100 mm, were tested. All specimens had the same geometrical characteristics. All the specimens were cast, instrumented and tested in the Structural and Materials Laboratory at PUC-Rio. The objective of this work was to study the influence of concrete strength and the width of the fabric on the bond strength of the system. The results showed that the ultimate bond strength may be considered independent of concrete strength and of the width of the fabric. A characteristic value of 1.45 MPa was found for the bond strength.
