Contributing with recycling of polymers in automotive industry, recycled polyvinyl butyral (rPVB) from automotive windshields is being explored as a solid lubricant reinforcement for improving lubricity of engineering polymers. This work aims to evaluate the tribological behavior (CoF and wear resistance) of polyamide 6 (PA6) and glass fiber reinforced polyamide 6 (PAGF) blended with rPVB as solid lubricant under two-body and three-body abrasive conditions. The different polymer blends were produced by adding recycled polyvinyl butyral (rPVB) into a matrix of either a commercial polyamide 6 (PA6), and a commercial 30% glass-fiber reinforced polyamide 6 (PAGF). The tribological tests were conducted in an instrumented micro-abrasion tester for generating wear and measuring coefficient of friction (CoF) in both dry and micro-abrasion conditions. In dry condition, rPVB was effective to reduce CoF for both PA6 and PAGF. Two-body abrasion was found as the predominant wear pattern in dry condition. On the other hand, in micro-abrasion condition, the additions of rPVB were not totally effective since they produced a wear resistance increase for PAGF but a reduction for PA6, which was ascribed to a notable decrease in toughness for PA6 when adding rPVB. Well defined ploughing traces and several SiC particles embedded in the scars were the predominant patterns in all the materials. In both PA6 and PAGF, CoF increased by the rPVB additions.
