RESUMO
An experimental investigation on the effects of impact loading on the bond strength between carbon fiber composite and concrete is described in this work. The objective was to verify the influence of loading rate on the bond strength. The experimental program consisted on testing of forty five specimens made of concrete blocks and carbon fiber strips glued on opposite sides of the block. The variables studied were the concrete compressive strength (25 MPa, 45 MPa and 65 MPa) and loading rate which varied from a minimum of 1,92 MPa/s (static) to a maximum of 438685 MPa/s (dynamic). Test results showed that the bond strength was affected by loading rate.
