Abstract: Fibre-reinforced composite materials are becoming important in many areas of technological application. In addition to the static load, such structures may be stressed with short-term dynamic loads or even dynamic impact loads during their lifespan. Dynamic effects can be significant especially for thin-walled shell structures and barrier constructions. Impact loading of construction components produces a complex process, where both the characteristics of the design itself and the material parameters influence the resultant behaviour. It is clear that reinforced concrete with fibers has a positive impact on increasing the resistance to impact loads. However, the assessment of the increase of this resistance has not been sufficiently verified experimentally. The first part of the project: laboratory load tests, aiming not only to determine the appropriate shape of test specimens, but also to evaluate and select appropriate ways to support the test specimens can be found in paper references [5, 6]. The second part of the project: results of impact load tests carried out on circular specimens with different shape and amount of the fibers are presented in this paper.
