Embodiment 1
[0029] Example 1: The material composition is aramid fiber and nylon fiber 28.6%, alumina 3.4%, graphite 1.7%, barite 2.4%, potassium feldspar powder 1.7%, kaolin 2.7%, molybdenum disulfide 0.7%, fluorite powder 1.7% %, phenolic resin 57.1%.
[0030] Step 1: Put the chopped aramid fibers and nylon fibers into the cotton feeder. After the opener loosens them, they are combed into a thin web of single fibers by a carding machine, and then airlaid to obtain a three-dimensional non-directional fiber web. After the fiber web is laminated layer by layer, the needle punch density is 26 needles / cm by the needle punching machine. 2 Acupuncture is performed with the parameters of , to obtain a loose and porous non-woven fiber preform A;
[0031] Step 2: Weigh 14.3% by weight of the phenolic resin of the friction material and dissolve it in an anhydrous ethanol solution to obtain an alcohol solution B of 20% by weight of the phenolic resin, and spray the solution B evenly on the non-wov...
Embodiment 2
[0035]Example 2: The material composition is aramid fiber and carbon fiber pre-oxygen filament 28.6%, alumina 3.0%, graphite 1.7%, barite 2.4%, potassium feldspar powder 1.7%, kaolin 2.7%, molybdenum disulfide 0.7%, fluorite Stone powder 1.7%, carbon black 0.4%, phenolic resin 48.5%, liquid silicone rubber 8.6%.
[0036] Step 1: Put the chopped aramid fiber and carbon fiber pre-oxygen filament into the cotton feeder. After the opener loosens it, it is combed into a thin single-fiber web by the carding machine, and then air-laid to obtain a three-dimensional non-directional fiber web. After the fiber web is superimposed layer by layer, the needle punching machine is used for the needle punching density of 26 needles / cm. 2 Acupuncture is performed with the parameters of , to obtain a loose and porous non-woven fiber preform A;
[0037] Step 2: Weigh 14.3% by weight of the phenolic resin of the friction material and dissolve it in an anhydrous ethanol solution to obtain an alcoh...
Embodiment 3
[0041] Example 3: The material composition is aramid fiber and carbon fiber pre-oxygen 22.2%, alumina 5.3%, graphite 2.6%, barite 3.7%, potassium feldspar powder 2.6%, kaolin 4.2%, molybdenum disulfide 1.0%, fluorite Stone powder 2.0%, sublimation sulfur 0.8%, phenolic resin 42.3%, nitrile rubber 13.3%.
[0042] Step 1: Put the chopped aramid fiber and carbon fiber pre-oxygen filament into the cotton feeder. After the opener loosens it, it is combed into a thin single-fiber web by the carding machine, and then air-laid to obtain a three-dimensional non-directional fiber web. After the fiber web is superimposed layer by layer, the needle punching machine is used for the needle punching density of 26 needles / cm. 2 Acupuncture is performed with the parameters of 1 to obtain a loose and porous non-woven fiber preform A;
[0043] Step 2: Weigh 11.1% by weight of the phenolic resin of the friction material and dissolve it in an anhydrous ethanol solution to obtain an alcohol soluti...
