Abstract: Paper-based friction material was prepared by wet-forming assisted hot-pressing process. The compatibility of
steel pairs with different carbon contents and paper-based friction materials in oil-free state and oil-rich state was
investigated, respectively. The friction mechanism in oil-free and oil-rich state was also discussed through wear surface
analysis. Results showed that in the oil-free state, as the hardness of the matching material increased, the friction
coefficient of the paper-based friction material decreased, the friction stability increased, and the wear rate decreased.
The 65Mn steel with high hardness had better compatibility with paper-based friction materials. The failure mode of
paper-based friction material in the oil-free state was fiber debonding and pulling-out caused by fatigue cracks. In the
oil-rich state, the hardness of the steel had no significant effect on the tribological properties of the paper-based friction
