Plastic recycling in the automotive industry is a priority. In this study, the effect of adding recycled polyvinyl butyral (rPVB) from automotive windshields on the coefficient of friction (CoF) and specific wear rate () of a glass-fiber reinforced polyamide (PAGF) is investigated. It was found that, at 15 and 20 wt.% of rPVB, it acts as a solid lubricant, reducing CoF and up to 27% and 70%, respectively. Microscopical analysis of the wear tracks showed that rPVB spreads over the worn tracks, forming a lubricant layer, which protects the fibers from damage. However, at lower rPVB content, fiber damage cannot be prevented as the protective lubricant layer is not formed.
汽车行业中的塑料回收是一个优先事项。在本研究中，研究了添加来自汽车挡风玻璃的回收聚乙烯醇缩丁醛（rPVB）对玻璃纤维增强聚酰胺（PAGF）的摩擦系数（CoF）和比磨损率（）的影响。结果发现，当rPVB含量为15%和20%（重量）时，它起到固体润滑剂的作用，分别使CoF和降低了27%和70%。对磨损轨迹的微观分析表明，rPVB分布在磨损轨迹上，形成一层润滑剂层，保护纤维免受损伤。然而，在较低的rPVB含量下，由于未形成保护性润滑剂层，无法防止纤维损伤。
