This study evaluated the effect of fiber on pull-out and tensile properties by conducting pull-out tests and direct tensile tests on hooked steel fiber (HSF), bundle-type polyamide fibers (PA), and amorphous metallic fibers (AF) with various physical properties and shapes. As a result, the hooked steel fiber was pulled-out, and the bonding stress and mechanical bonding stress of the fiber and the matrix had a great influence on the tensile performance. PA and AF showed fracture behavior, and the tensile performance of the fiber itself had a great influence on the tensile properties.
