通过对原料特性和配方进行调节，探究了棉纤维打浆度、碳纤维形态、摩擦粉含量和树脂弹性模量对湿式纸基摩擦材料压缩回弹性的影响，同时设计了 4 种具有不同压缩回弹性的纸基摩擦材料，分析了压缩回弹性对湿式纸基摩擦材料摩擦磨损性能的影响。研究结果表明: 棉纤维打浆度在 20^oSR 以上时，材料具有良好的尺寸稳定性; 长3mm的短切碳纤维、乙醇溶剂型高弹性模量粘结树脂可提高样品的尺寸稳定性; 摩擦粉的加入可提高材料的稳定压缩率; 压缩回弹性对摩擦磨损性能有重要的影响，当湿式纸基摩擦材料的永久形变率在 4. 0% 以下、稳定压缩率在 7. 0% 以上时，材料的摩擦磨损性能较为优异。

The effects of beating degree of cotton fiber，carbon fiber morphology，friction powder content and resin elastic modulus on the compression-resilience property of wet paper-based friction materials were investigated by adjusting the raw material characteristics and formula． And 4 paper-based friction materials with different compres-sion-resilience property were prepared to explore the influence of compression-resilience property on the friction and wear performance． The results show that the material has good dimensional stability when the beating degree of cot-ton fiber is above 20^o SR; the short carbon fiber of 3 mm and ethanol solvent type resin with high elastic modulus can improve the dimensional stability of the samples; the stable compression ratio can be improved by adding the friction powder; the compression-resilience property has significant influence on friction and wear performance． The friction and wear performance of the material is rather better when the permanent deformation rate of the wet paper-based friction material is below 4. 0% and the stable compression ratio is above 7. 0%．
