Embodiment 1
[0023] A method for preparing a ceramic composite fiber brake pad, comprising the following steps:
[0024] 1) Mixing: Add the brake pad friction base material into the mixer. The friction base material includes the following components in parts by weight: 15 parts of 2123 resin, 8 parts of graphite, 5 parts of tire powder, 6 parts of barium sulfate, 3 parts of modified glass fiber, 5 parts of wollastonite, 3 parts of ceramic fiber, 12 parts of composite fiber, 2 parts of rubber powder; The mixing time is 2h;
[0025] 2) Heating vulcanization: use a high-tonnage hydraulic press to heat-press the mixture, control the pressure at 20Mpa, and control the temperature at 100°C, and then vulcanize;
[0026] 3) Heat treatment: put the mixture obtained by heating and vulcanization into an oven for heat treatment, and the heat treatment temperature is 130°C;
[0027] 4) Post-processing: The mixture obtained after heat treatment is subjected to flat chamfering, rough outer arc, inner a...
