This study details the development of textured composite surfaces with evolution of the coefficient of friction on ice with varying fiber types and matrices. Different types of fibers, such as metallic and carbon based, were melt blended with Thermoplastic polyurethane (TPU) and Styrene-Butadiene Styrene (SBS) matrices in equal volume fractions. The texturing process involved a mechanical ablation technique to expose the fibrous phase from the surface of the composite using fiber de-bonding and pull-out. The surface properties of these textured composites were compared to their pure counterparts, and the effect of the coefficient of friction of these surfaces on ice was determined before and after simulated wear. Surface characterization techniques, including roughness testing and Scanning electron microscopy images, were conducted to determine the effect of abrasion on the frictional properties of the composite surfaces.
