Deformation and destruction of layered carbon fiber reinforced concrete structures under shock-wave loading
The processes of deformation and destruction of layered structures reinforced with carbon fiber on the front and back sides of concrete slabs under shock-wave loading are studied. A model is proposed that describes these processes in the framework of continuum mechanics. The influence of the front and back layers of carbon fiber reinforcement of barriers made of fine-grained concrete on the process of penetration by a steel indenter was studied in the range of meeting speeds of 1000-1500 m/s. It is established that to break through the barrier of fine-grained concrete reinforced with carbon fiber from the front and back surfaces, it is necessary to spend more energy by 120% compared to the penetration of the non-reinforced barrier.
