摘要

使用加速测试技术评估了来自两家供应商的八种商用聚酰亚胺和三种实验聚酰亚胺的摩擦和磨损性能，并将其作为温度的函数进行了评估。未填充和填充的材料，包括ptfe, MoS2，玻璃纤维或石墨。含石墨的复合材料明显优于其他材料，但即使是这些材料，磨损率也随着温度的升高而迅速增加。所有含石墨的材料表现出非常相似的方式，这是由于复合材料中的石墨成分主导了磨损行为。

Friction and wear of some polyimides

The friction and wear properties of eight commercially-available polyimides from two suppliers, and three experimental polyimides have been assessed as a function of temperature, using an accelerated test technique. Both unfilled and filled materials, containing ptfe, MoS₂, glass fibres or graphite were included. Composites containing graphite were markedly superior to the other materials, but even with these, rates of wear increased rapidly with increasing temperature. All graphite-containing materials behaved in a very similar manner, and this is attributed to domination of the wear behaviour by the graphite component of the composite.
