Abstract Five kinds of composite brake with phenolic resin mass percent of 4%-12% was prepared through hot pressing method. The Link3000 inertia friction test bench, Link3900 NVH inertia friction test bench and Link3336 compression testing machine were used to test the friction performance, noise performance and compression performance of the brake. The effect of phenolic resin content on the friction and wear properties of the brake were discussed combined with the microstructure and mechanical properties analysis. Results show that with the increase of phenolic resin content, the average friction coefficient and high temperature friction coefficient decrease, leading to recession. At the same time, the braking noise, the noise probability and the noise intensity increase. When the mass percent of phenolic resin is 6%, the friction coefficient has the best stability, which is not easy to cause recession; and the noise probability is the minimum when the mass percent of phenolic resin is 4%-6%.
