The stick–slip phenomena of various types (halloysite, montmorillonite and wollastonite) of clay-based composite friction materials were evaluated in terms of their velocity-dependent friction response. Scanning electron microscopy of the contact patches suggested breakage of contact plateaus in the composites with halloysite, whereas relatively small contact patches were developed in montmorillonite-based friction composites. The presence of relatively harder ingredients such as magnesium oxide and iron particles on the worn surface have contributed to the stick–slip phenomenon. The presence of wollastonite in the composites leads to the ploughing effect during sliding. The intensity of creep groan remained controlled by the shear strength of the interfacial junction involving asperity contact/welding whereas dynamic groan remains predominated by the stiffness of the composites.

根据与速度有关的摩擦响应，评估了各种类型（黏土，蒙脱土和硅灰石）黏土复合摩擦材料的粘滑现象。接触斑的扫描电子显微镜表明，具有埃洛石的复合材料中的接触平台破裂，而基于蒙脱石的摩擦复合材料中形成了相对较小的接触斑。在磨损的表面上存在相对较硬的成分，例如氧化镁和铁颗粒，导致了粘滑现象。复合物中硅灰石的存在导致滑动过程中的耕作效果。
