    • Abstract

       

      The article presents a novel hybrid concrete composite which is produced by combining glass and basalt textiles for achieving enhanced impact resistance compared to their independently reinforced counterparts. A full factorial analysis was performed to determine the synergy of two types of textiles and theircombination on the impact strength and energy absorption. The two levels of key factors were considered for analysis such as the type of textile and impact energy level, and variance. The influencing parameters showed statistical significance with more than a 90% confidence level concerning impact resistance and energyabsorption. The combination of two textiles showed the highest impact resistance irrespective of the energy levels, compared to the use of single textiles. The findings demonstrated that the energy absorption of hybrid textile reinforced concrete is not significantly enhanced with the increasing level of impact energy. At the high levels of impact energy, in comparison to the hybrid textile reinforced concrete slabs and basalt textile reinforced concrete, more energy is absorbed by the glass textile reinforced concrete slabs. Thus, in hybrid textile reinforced concrete, it is indicated by the failure pattern that combining basalt and glass textile influences the degree of local failure. Therefore, this research emphasizes on the synergy to customize and optimize textile reinforced concrete with superior impact resistance and energy absorption for the protection of structures in theevent of impact loading.
