    AnnotationThe impact resistance of fibre reinforced concrete was investigated using a Taylor impact test.Striking velocities up to 31 m/s were applied. The four types of fibre was used: carbon,polypropylene, aramid and wollastenite. The results showed that the dynamic compressive strength increased with the striking velocity. The highest rate sensitivity was reported for carbon and polypropylene fibres.The addition of aramidfibres did not led to the increase of the compressive strength in comparison with the unreinforced concrete. The dynamic compressive strength lies between static compressive strength and the dynamic strength evaluated using a Split Hopkinson Pressure Bar technique. Qualitative features of the specimen damage were studied using high speed camera.
