Polyketone-Polypropylene Core-Shell Fibers for Concrete Reinforcement
- Corrosion of the commonly used steel reinforcements weakens the structural strength of concrete. 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.
