摩擦材料和基板间要有很强的黏结强度，以保证摩擦材料的机械性能和使用寿命以及制动的安全性。研究不同剪切温度下，表面未经处理和经喷砂处理的基板与摩擦材料的黏结强度。结果表明：摩擦材料与基板的黏结强度均随剪切温度的增加先增大后减小；基板经过喷砂处理后，与摩擦材料的黏结强度和未经喷砂处理基板相比在较低剪切温度下差别不大，但在较高剪切温度下具有较大的黏结强度。不同剪切温度下树脂基摩擦材料具有不同的断裂机制，温度较低时，断裂面为摩擦材料和黏结剂的界面靠近摩擦材料一侧；温度较高时，断裂面为黏结剂间的界面；而随着剪切温度的进一步提高，断裂面转向基板和黏结剂的界面。

There must be strong bond strength between friction material and the substrate to ensure the mechanical prop?erties and service life of friction material as well as the safety of the brake.The bond strengths of the friction material with the untreated substrate and with the sandblasting substrate were studied under different shear temperature.The results show that with the increase of the shear temperature,the bond strength of the friction material with the substrate is increased firstly and then decreased.At low shear temperature,there is not obvious difference of the bond strength of the friction ma?terial with the untreated substrate and with the sandblasting substrate.While at high shear temperature,the bond strength of the friction material with the sandblasting substrate is evidently higher than that of the friction material with the untreated substrate.Resin?based friction material and substrate present different fracture mechanism under different shear tempera?ture. At lower temperature,fracture surface is in the interface of friction material and adhesive which is closer to the fric?tion material’s side,while at higher temperature,fracture surface is in the interface between adhesives.And fracture inter?face changes to the interface between substrate and adhesive with the further increase of shear temperature.
