Background
The resin-based friction material is a novel structural functional material which is composed of high-performance fibers and a resin matrix and has the excellent performances of weak dual damage, small friction and vibration, small noise, strong wear resistance and the like. The carbon fibers are main reinforcing fibers of the resin-based friction material, play a skeleton role in the resin-based friction material and bear load, provide strength and rigidity for the resin-based friction material, and play a vital role in determining the tribological characteristics of the friction material. However, the carbon fibers have smooth and chemically inert surfaces, so that the interface interaction between the carbon fibers and the resin matrix is weak, and the fibers and the resin matrix are easily debonded during the friction process, thereby causing severe abrasion of the friction material. Therefore, there is a need to improve the surface properties of the fibers, enhance the interfacial properties of the fibers with the resin matrix, and thereby improve the tribological properties of fiber-reinforced resin-based friction materials.

The MWCNT with controllable growth is introduced into the field of friction materials, so that an important reference basis is provided for structural design and engineering application of resin-based friction materials, and a theoretical basis is laid.
