Embodiment 1
[0039] A method for preparing an anti-wear carbon / ceramic brake material, comprising the steps of:
[0040] (1) Firstly, the purchased T700 chopped carbon fiber is made into a short-fiber tire mesh, and the tire mesh is stacked in sequence, and then the relay-type needling method is used to needle the above-mentioned layered and stacked tire mesh with barbs. During the acupuncture process, the claws of the barbed needles bring the fibers of each tire mesh layer to the vertical direction, so that the tire meshes are connected into one body, and the three-dimensional tire mesh needle-punched prefabricated body is obtained. Cut the three-dimensional tire mesh needle-punched preform into a ring shape with an outer diameter of 400mm, an inner diameter of 150mm, and a thickness of 60mm. The needle-punched hole density in the three-dimensional tire mesh prefabricated body is 10 holes / cm 2 , the volume content of carbon fiber is about 15%, and the density of the three-dimensional tir...

[0048] A method for preparing an anti-wear carbon / ceramic brake material, comprising the steps of:
[0049] (1) Firstly, the purchased T700 chopped carbon fiber is made into a short-fiber tire mesh, and the tire mesh is stacked in sequence, and then the relay-type needling method is used to needle the above-mentioned layered and stacked tire mesh with barbs. During the acupuncture process, the claws of the barbed needles bring the fibers of each tire mesh layer to the vertical direction, so that the tire meshes are connected into one body, and the three-dimensional tire mesh needle-punched prefabricated body is obtained. Cut the three-dimensional tire mesh needle-punched prefabricated body into a ring shape, with an outer diameter of 350mm, an inner diameter of 150mm, and a thickness of 70mm. The needle-punched hole density in the three-dimensional tire mesh prefabricated body is 8 holes / cm 2 , the volume content of carbon fiber is about 15%, and the density of the three-dime...
Embodiment 3
[0056] A method for preparing an anti-wear carbon / ceramic brake material, comprising the steps of:
[0057](1) Firstly, the purchased T700 chopped carbon fiber is made into a short-fiber tire mesh, and the tire mesh is stacked in sequence, and then the relay-type needling method is used to needle the above-mentioned layered and stacked tire mesh with barbs. During the acupuncture process, the claws of the barbed needles bring the fibers of each tire mesh layer to the vertical direction, so that the tire meshes are connected into one body, and the three-dimensional tire mesh needle-punched prefabricated body is obtained. Cut the three-dimensional tire mesh needle-punched preform into a ring shape with an outer diameter of 300mm, an inner diameter of 120mm, and a thickness of 50mm. The needle-punched hole density in the three-dimensional tire mesh prefabricated body is 9 pcs / cm 2 , the volume content of carbon fiber is about 15%, and the density of the three-dimensional tire me...
