2016-1-1  The present results are consistent with the trend reported in , where the increase in the abrasive wear of talc-filled polypropylene increased as the amount of filler increased. Similarly, Chu et al. [29] found that the addition of 20 wt% talc particles to polypropylene more than doubled the scratch depth, attributing this to talc/resin debonding and delamination within the talc particles.
