This paper presents results of extensive experimental programme which took place in 2019. Two proprietary ultra-high performance fibre reinforced composite materials were tested for their blast (contact and close-in) resistance. In total, twenty-eight specimens were tested. Specimens were loaded with explosive charge of weight of 100 -1000 g in various distances. All specimens were visually evaluated for the damage extend, failure mode and crack pattern. Results from the experiment were

Results showed that both tested premixes performed better than ordinary mixtures in terms of blast resistance. Difference between tested materials and commonly used mixture are described as well. Finally, both materials were compared from the material properties point of view as well as by their blast resistance performance.
