The wear resistance of unidirectional carbon fiber reinforced epoxy under severe abrasive sliding conditions was studied. It was found that unidirectional laminates tested with the fibers parallel to the sliding direction (UDp) were more wear resistant than the same laminates tested with fibers transverse to the sliding direction (UDap) under the same set of test conditions. A novel energy-based model was developed to explain the difference in the wear rates. It was found that the difference in wear rates between the two orientations was due to differences in the average volume to surface area ratio of the debris, the energy required to generate new surfaces, and a new k factor that represents the fraction of the total friction energy used for creating wear particles. Furthermore, wear volume per sliding distance was found to be linearly proportional the total frictional energy dissipation for both orientations. These findings can be used to simplify wear predictions for industrial applications.

基于能量的单向碳纤维增强环氧树脂磨损模型

研究了单向碳纤维增强环氧树脂在严重磨损滑动条件下的耐磨性。结果发现，在相同的一组测试条件下，用平行于滑动方向 (UDp) 的纤维测试的单向层压板比用横向于滑动方向 (UDap) 的纤维测试的相同层压板更耐磨。开发了一种新的基于能量的模型来解释磨损率的差异。发现两种取向之间磨损率的差异是由于碎屑的平均体积与表面积之比、产生新表面所需的能量以及代表总摩擦分数的新 k 因子的差异造成的。用于产生磨损颗粒的能量。此外，发现每滑动距离的磨损量与两个方向的总摩擦能量耗散成线性比例。这些发现可用于简化工业应用的磨损预测。
