The authors have studied the alterations in cleat-surface friction of AstroTurf associated with use and exposure. Three cleat types were studied on five year old turf and on an unused, unexposed turf sample of the same production batch. Tests were carried out with and against surface grain under wet and dry conditions. It was found that with use and exposure the surface friction of AstroTurf does change, affecting both player performance and safety.
作者研究了人造草皮防滑钉表面摩擦力随使用和暴露情况的变化。在使用了五年的草皮以及同一生产批次未使用、未暴露的草皮样本上，对三种防滑钉类型进行了研究。在干湿条件下，分别沿着草皮纹理和逆着草皮纹理进行了测试。结果发现，随着使用和暴露，人造草皮的表面摩擦力确实会发生变化，这会影响运动员的表现和安全。
