摘　　要：利用无机纤维和有机纤维(无金属纤维)混杂增强,采用无机粘结剂(无树脂或少量树脂)和有机或无机材料作为摩擦性能调节剂,通过特定工艺制备新型陶瓷基汽车刹车片。研究了这种新材料的物理、力学性能和摩擦磨损性能,并与树脂基摩擦材料进行了性能对比。研究结果表明:新型陶瓷基摩擦材料密度适中(约2.0 g.cm-3),在相同条件下新型陶瓷基刹车片的磨损率远远低于树脂基刹车片,且其摩擦系数稳定性、抗热衰退性能及制动舒适性均明显高于树脂基摩擦材料。A new ceramic-based automotive braking pads were prepared by using inorganic and organic fiber（non metallic fiber） multi-reinforcing,inorganic binder（non resin or little resin） and organic or inorganic materials as friction modifiers,and specific process.The physical mechanical and friction performance were investigated,and comparison with the resin-based friction material was made.It is shown that the density of the new ceramic-based automotive braking pads is moderate（about 2.0 g·cm-3）.The wear rate is also much lower.The stability of friction coefficient,anti-thermal-recession performance and brake comfortableness are obviously better than those of the resin-based friction material,under same testing conditions.
