| 中文摘要 | 纸基摩擦材料属多孔材料,其摩擦磨损性能与压缩回弹性能密切相关。研究了纸基摩擦材料纤维的含量及类型、树脂的含量,以及材料的孔隙率对其压缩回弹性能的影响。结果表明,材料配方及孔隙率会显著改变材料的压缩率和回弹率。纤维和树脂含量的增加都会造成纸基摩擦材料压缩率的降低和回弹率的升高。其中,树脂含量对材料压缩率的影响较大,纤维含量对材料回弹率的影响较大。加入混杂纤维的材料比较单纯采用芳纶纤维浆粕的材料具有更低的压缩率和更高的回弹率,其中混杂有纸浆纤维的材料压缩回弹性能最好。纸基材料的孔隙率越大,材料压缩率越大,回弹率越低。; As a porous material, paper-based friction material's friction performance is closely related to its compressive properties including compression and resilience rate. The influence of different types and contents of fibers, contents of phenolic resin and porosity on the compressive properties of paper-based friction materials were investigated by compression-resilience test. The results show that lower compression ratio and higher resilience rate are caused by the increase of the contents fiber and resin, in which the influence of resin on compression ratio is larger than that of fiber, and the influence of fiber on resilience rate is larger than that of resin. Materials with ramie fiber or paper pulp-fiber are found to have lower compression ratio and higher resilience rate than materials with only aramid pulp, and materials with paper pulp-fiber have slightly higher compression rate and resilience rate than materials with ramie fiber. It is found that materials with higher porosity have higher compression rate and lower resilience rate. |
