RESUMO
An experimental investigation on the effects of impact loads on the bond strength between carbon fiber composite and concrete is described in this work. The objective was to investigate the influence of loading rate on the bond strength. Concrete-fiber specimens were tested under loading rates varying from a minimum of 6,06 MPa/s (static) to a maximum of 3.690.485 MPa/s. In addition, twenty tree concrete prisms were tested under different loading rates in order to investigate the effects of the loading rate on the tensile strength of concrete and carbon fiber separately. The results show that the bond strength increase with the increase of the loading rates.
