Friction and wear of periodically micro-patterned polypropylene in dry sliding

► Influence of micro-patterning on sliding friction and wear of polypropylene disks. ► Filtering of friction data to study the different stages of sliding on steel disk. ► Two different friction behaviors were detected in a single measurement. ► Wear of polypropylene surface decreased with denser micro patterning. ► Sliding friction of polypropylene was slightly affected by micro patterning.
