Embodiment 1
[0028] This embodiment provides a friction material, which includes 26 parts by weight of metal fibers, 4 parts by weight of phenolic resin, 2 parts by weight of nitrile rubber, 50 parts by weight of barium sulfate, 4 parts by weight of aluminum oxide, 4 parts by weight of chromite, graphite 5 parts by weight, 3 parts by weight of petroleum coke particles and 2 parts by weight of mica.
[0029] Such as figure 1 As shown, the metal fiber includes a plurality of composite nickel-tin metal fiber filaments 2 , and the plurality of composite nickel-tin metal fiber filaments 2 are distributed in the matrix 1 of the friction material in a disordered state. Such as figure 2 As shown, the nickel fiber 3 is the main body in each composite nickel-tin metal fiber wire, and the tin fiber is divided into multiple sections and wound on the nickel fiber 3 from bottom to top, and the head and end of each section of tin fiber 4 protrude from both sides of the main trunk. . In this embodimen...
Embodiment 2
[0040] This embodiment provides a friction material, which is roughly the same as that of Embodiment 1, except that it includes 30 parts by weight of metal fibers, 3 parts by weight of phenolic resin, 2 parts by weight of nitrile rubber, 47 parts by weight of barium sulfate, 4 parts by weight of aluminum oxide parts by weight, 4 parts by weight of chromite, 5 parts by weight of graphite, 3 parts by weight of petroleum coke particles and 2 parts by weight of mica. In this embodiment, the diameter of the nickel fiber 3 is 100 μm, and the length of the nickel fiber 3 is 1.5 cm. The diameter of each tin fiber 4 is 25 μm, and the length of each tin fiber 4 is 1.5 cm.
[0041] This embodiment also provides a friction product, which is prepared by the following method:
[0042] 1) if image 3 As shown, a thermosetting mold is provided, the mold includes a mold frame 5, an upper electrode pressing plate 6 and a lower electrode pressing plate 7, the mold frame 5 is an insulating cera...
Embodiment 3
[0050] This embodiment provides a friction material, which is roughly the same as that of Embodiment 1, except that it includes 25 parts by weight of metal fibers, 3 parts by weight of phenolic resin, 2 parts by weight of nitrile rubber, 52 parts by weight of barium sulfate, 4 parts by weight of aluminum oxide parts by weight, 4 parts by weight of chromite, 5 parts by weight of graphite, 3 parts by weight of petroleum coke particles and 2 parts by weight of mica. The diameter of the nickel fiber 3 is 100 μm, and the length of the nickel fiber 3 is 1.5 cm. The diameter of each tin fiber 4 is 25 μm, and the length of each tin fiber 4 is 1.5 cm.
[0051]This embodiment also provides a friction product, which is prepared by the following method:
[0052] 1) image 3 As shown, a thermosetting mold is provided, the mold includes a mold frame 5, an upper electrode pressing plate 6 and a lower electrode pressing plate 7, the mold frame 5 is an insulating ceramic material, and the up...
