This paper presents an experimental testing on FRP to concrete interface using a double lap shear tests. The FRP is a carbon/expoy composite made of carbon fiber sheet applied by wet lay up method. The experimental test is based on 16 specimens tested under displacement control conditions with 4 different speed ranging from 0.017 m/s to 0.8 m/s. The results are analysed based on load transfer between FRP and concrete, failure load, local bond slip relation and failure modes. The tests shows that the strength of the FRP to concrete in shear is not affected by dynamic loading rate with an ultimate bond strength value that depends on the dynamic properties on concrete in shear. The conclusion of the test allows to compare available relation existing in literature for design and include a proposal to consider the effect of speed rate. The results allows also to conclude on the good behaviour of FRP in case of dynamic loading conditions.
