蛤蜊壳粉在有机陶瓷型摩擦材料中的应用研究

以酚醛树脂为基体，氧化镁为固化剂，针状硅灰石为纤维增强体，蛤蜊壳粉、锆英石、重晶石、钛酸钾片晶为填料，石墨为固体润滑剂，蛭石为降噪剂，设计了含蛤蜊壳粉的陶瓷型有机摩擦材料配方。用蔡斯（Chase）摩擦试验机测定了摩擦材料的摩擦性能，用可拓评价法分析了蛤蜊壳粉对摩擦系数和磨损率的影响。实验结果表明，蛤蜊壳粉可以在摩擦材料中应用。

Application of clam shells in organic ceramic friction materials

Organic ceramic friction materials containing clam shells have been prepared using a phenolic resin as a matrix, magnesium oxide as a curing accelerator, wollastonite as a reinforcing fiber, clam shells, zircon, barite and potassium titanate as fillers, graphite as a solid lubricant and vermiculite as a noise reduction agent. The friction performance of the composites was tested by a Chase procedure and evaluated by an extension method. The results showed that clam shells can be employed in organic ceramic friction materials.
