Embodiment 1
[0045] Example 1 Aramid fiber is added to the preparation of a high friction coefficient synthetic brake shoe. The initial thermal decomposition temperature of the aramid fiber is as high as 500°C, and it does not melt when heated to decomposition. This is particularly important for friction materials. Aramid fiber Reinforced friction material has the following advantages: stable friction coefficient at high and low temperature, low wear; good reinforcement effect, strong impact resistance; low product hardness, low product noise, and no damage to the brake dual.
[0046] (1) Steel back treatment
[0047] 1.1 Hang the qualified high friction coefficient synthetic brake shoe steel back on the shot blasting basket in the shot blasting machine for shot blasting and rust removal.
[0048] 1.2 The steel back with excessive shot blasting deformation is corrected one by one with tooling.
[0049] 1.3 Spray the surface of the steel back corrected by shot blasting and rust removal, and then dr...
Embodiment 2
[0061] Example 2 Aramid fiber is added to the preparation of a high friction coefficient synthetic brake shoe. The initial thermal decomposition temperature of aramid fiber is as high as 500°C, and it does not melt when heated until it is decomposed. This is particularly important for friction materials. Aramid fiber Reinforced friction material has the following advantages: stable friction coefficient at high and low temperature, low wear; good reinforcement effect, strong impact resistance; low product hardness, low product noise, and no damage to the brake dual.
