| 发明名称 | Paper-based wet friction material of automotive auto transmission | ||
| 摘要 | A multilayer paper-based wet friction material of an automotive auto transmission may improve noise and vibration characteristics, heat resistance, wear resistance, compression resistance, and oil absorbency. The paper-based wet friction material of an automotive auto transmission includes: a first layer using cellulose pulp as a matrix and including a first functional additive; a second layer stacked on the first layer, using the cellulose pulp as the matrix, and including the second functional additive; and a hydrogen bonding layer mediating between the first layer and the second layer. The cellulose pulp of the first and second layers is cotton linter. | ||
