Polypropylene (PP)-fibers are one of the most widely used polymer fibers for several different applications in fiber reinforced concrete due to their availability, low price, chemical inertness and stability in high alkaline environment. In order to improve the fracture energy and toughness of fiber-reinforced mineral-based composites under impact loads, the energy absorption provided by the fiber material itself but also the failure mechanisms in the fiber-matrix interphase play a crucial role. A desirable pull-out behavior for high energy absorption is achieved for polymer fibers with high tensile strength in combination with high surface roughness. Based on this knowledge, new PP-bicomponent fibers have been developed containing different particles (e.g. Al₂O₃, CaCO₃) in the outer shell in order to generate a rough fiber surface. In this work the results of first spinning trials of PP-bicomponent fibers produced by a lab-scale spinning equipment are presented. The fibers` tensile strength and particle distribution along the surface was determined depending on the drawing ratio. In single-fiber pull-out tests the fibers enabled high energy absorption compared to state-of-the-art PP-fibers. Furthermore, the structure of the fibers surface before and after pull-out was analyzed by scanning electron microscopy and revealed enhanced mechanical interlocking.
