| Abstract: |
| To improve the deposition of carbon fiber on based paper of paper-based friction materials and its strength properties， the effects of tributyl phosphate （TBP） and cationic polyacrylamide （CPAM） on the abovementioned issues were studied. The results showed that the addition of TBP could effectively improve deposition of carbon fiber on surface of the base paper； there was no aggregated carbon fiber on surface of the paper with 3 wt% TBP while strength properties of the paper were reduced. When the dosages of CPAM and TBP were 0.03 wt% and 3 wt%， respectively， the tensile index and internal binding strength of the base paper increased by 23.9% and 82.0%， respectively， compared with the control group （TBP dosage of 3 wt%）， and deposition of carbon fibers on the base paper surface was improved. |
