Cementitious materials, such as mortar and concrete, exhibit brittle fracture behavior under tensile forces. Adding metallic fibers to these materials improves the element tensile behavior, but this improvement is a function of the fiber content, distribution, and orientation. In ultra high-performance fiber-reinforced composite (UHPFRC) materials, as in fiber-reinforced composite, the material's strength and hardening and softening behaviors can be significantly undermined if the reinforcing fibers are at a lower content than specified, poorly distributed, or incorrectly oriented. Here, Wuest offer a tomography analysis of fiber distribution and orientation in ultra high-performance fiber-reinforced composites with high-fiber dosages.
