Blending polypropylene (PP) to recycled polyamide (PA)-6 industrial wastes with and without compatibilizer was produced in a co-rotating twin-screw extruder, in which PP acts as the polymer matrix and PA as the dispersed phase. Friction and wear behaviours of PA6-filled PP composites were investigated on block-on-wheel model friction and wear tester. In order to further understand the wear mechanisms, worn surfaces and scraps of samples were analysed by a scanning electron microscope.
