Abstract

A new approach for the friction and wear characterisation of polymer fibres under dry, mixed, and hydrodynamic sliding conditions is developed. The production process of the tested polymer fibres is described and an introduction in fibre-reinforced concrete is given. Tribotesting is done on an optimised tribometer capable of measuring the friction and wear behaviour of polymer fibres with diameters of a few 100 µm under lubricated conditions. Three extruded polypropylene macro fibres with varying diameters are characterised under tribological conditions found in an industrial concrete mixing process. It is shown that detailed friction and wear data of polymer fibres can be gathered.

聚合物纤维在干滑、混滑和水动力滑动下摩擦磨损特性的新方法
研究了聚合物纤维在干燥、混合和水动力滑动条件下的摩擦磨损特性。介绍了所测聚合物纤维的生产工艺,并对其在纤维增强混凝土中的应用作了介绍。摩擦测试是在一个优化的摩擦计上进行的,该摩擦计能够测量直径为100微米的聚合物纤维在润滑条件下的摩擦和磨损行为。在工业混凝土搅拌过程中的摩擦学条件下,对三种不同直径的挤出聚丙烯宏纤维进行了表征。结果表明,该方法可以收集到聚合物纤维的摩擦磨损数据。
