稻壳炭增强制动摩擦材料的制备与性能
摘 要
制动摩擦材料的性能对车辆行驶安全至关重要，传统材料难以兼顾低环境负荷与高性能。为解决这一问题，本研究以稻壳炭作为增强相制备新型制动摩擦材料，旨在改善材料的摩擦磨损性能并降低环境污染。通过热压成型工艺将稻壳炭均匀分散于基体中，采用扫描电镜、X射线衍射等手段分析微观结构与物相组成，利用惯量试验台测试摩擦系数和磨损率。结果表明，适量稻壳炭可显著提高材料的摩擦系数稳定性，在不同温度和压力条件下表现出优异的抗衰退性，且磨损率明显降低。当稻壳炭添加量为5%时，综合性能最佳，摩擦系数稳定在0.38左右，磨损率较未添加样品降低了42%。该研究创新性地将农业废弃物稻壳转化为高附加值的增强材料，不仅拓宽了稻壳的应用领域，还为开发环保型高性能制动摩擦材料提供了新思路。

PREPARATION AND PROPERTIES OF RICE HUSK CARBON-ENHANCED BRAKE FRICTION MATERIALS
ABSTRACT
The performance of brake friction materials is critical to vehicle driving safety, while traditional materials struggle to balance low environmental impact with high performance. To address this issue, this study developed a novel brake friction material using rice husk carbon as an enhancer, aiming to improve the friction and wear properties while reducing environmental pollution. Rice husk carbon was uniformly dispersed in the matrix through hot pressing, and the microstructure and phase composition were analyzed using scanning electron microscopy and X-ray diffraction. The friction coefficient and wear rate were tested on an inertia dynamometer. Results indicate that an appropriate amount of rice husk carbon significantly enhances the stability of the friction coefficient, exhibiting excellent anti-fade properties under various temperature and pressure conditions, with a notably reduced wear rate. When the rice husk carbon content was 5%, the overall performance was optimal, with the friction coefficient stabilizing around 0.38 and the wear rate decreasing by 42% compared to samples without addition. This study innovatively transforms agricultural waste rice husks into high-value-added reinforcement materials, not only expanding the application scope of rice husks but also providing new insights for developing environmentally friendly, high-performance brake friction materials.
