To oppose this issue, concrete reinforcements in the form of polymer fibers are investigated. These polymer fibers need a good bonding ability to concrete and good mechanical properties. This study investigates core-shell fibers produced from polyketone and polypropylene mixed with a compatibilizer. The core-shell fibers were produced by coextrusion and drawing. The fibers were analyzed by tensile tests, a single fiber pull-out test, contact angle measurements, scanning electron microscopy and thermogravimetric analysis.}, language = {en} }
