摘要

本研究旨在研究硅灰石硅烷处理对非石棉有机摩擦刹车片材料力学性能和摩擦学性能的影响。制备了两个主要的刹车片摩擦衬片试样，分别含有处理过的硅灰石（Wt）和未处理过的Wo。对所有生产的样品进行了表征，并对其机械、化学和摩擦学性能进行了检查。实验结果表明，所有摩擦学性能参数都在可接受的标准范围内，并且所有样品的摩擦学性能在摩擦系数和褪色性能方面几乎相同。在磨损、恢复性能和圆盘温升（DTR）方面，Wt样品比Wu样品具有更好的性能，这归因于处理后硅灰石与聚合物基体之间具有良好的粘附性。此外，对测试样品进行了扫描电子显微镜分析，结果表明Wt的表面比Wu的表面总体上有所改善。最后，为了充分利用硅灰石硅烷处理的优势，建议在摩托车等操作条件较低的车辆中使用。

The effect of wollastonite silane-treatment on mechanical and tribological performance of NAO brake-pads

The current study aims to investigate the effect of silane-treatment of wollastonite on the mechanical, tribological performance of non-asbestos organic frictional brake-pad material. Two main friction lining specimens in the shape of brake-pads containing treated wollastonite (Wt) and untreated wollastonite (Wu) were produced to carry on the experiments. All produced samples were characterised and examined for their mechanical, chemical and tribological properties. The experimental results show that all parameters of tribological performance are within the acceptable standard range and that the tribological performance for all samples is almost the same in terms of friction coefficient and fade performance. Regarding wear, recovery performance and disc temperature rise (DTR), Wt samples offer better performance than Wu samples which was attributed to the good adhesion between wollastonite and the polymeric matrix after treatment. Moreover, scanning electron microscopy analysis is done on the tested samples and show overall improved surface of Wt than Wu. Finally, for full use of wollastonite silane-treatment advantages, it is recommended to be used in vehicles with less severe operating conditions such as motorbike and alike.
