Problems solved by technology

[0002] At present, carbon cloth, needle-punched carbon felt, needle-punched carbon fiber, etc. are used as brake disc matrix materials. The original form of these materials is roll material or square, which needs to be cut and laminated during use. Clamping devices are required in the production process of carbon brake discs, so the current production method of brake disc base has the disadvantages of low material utilization rate, low production efficiency, high production cost, complicated process, high labor intensity and harsh working environment

Embodiment 1

[0020] Embodiment 1, with reference to figure 1 , figure 2 , a method for making a carbon / carbon composite material brake disc is to prepare ready-to-use carbon fiber or preoxygenated wire, and fix or adjust the knitting needle on the diameter-adjustable inner and outer rings according to the pre-calculated needle pitch , first weave one layer along the X-axis or the radial direction, rotate the substrate within the range of 0-90°, then weave one layer along the Y-axis or the circumferential direction, rotate the substrate within the range of 0-90°, and repeat the above weaving steps , until the required matrix thickness is reached, adjust the length of the fiber used in the Z direction according to the thickness of the matrix, knit the adjusted fiber along the Z direction, and the needle distance in the Z direction can be adjusted arbitrarily according to requirements, and the weaving of the matrix can be completed. Chemical vapor deposition is performed on the braided subs...

Embodiment 2

[0021] Embodiment 2, with reference to figure 1 , image 3 , when performing matrix weaving, weave alternately on the same layer along the X-axis direction, the Y-axis direction or the radial direction and the circumferential direction until the required thickness is reached, and other steps are the same as in Embodiment 1.

Abstract

A method for making brake disk with carbon / carbon composite material features that its base body is made up by braiding instead of needling, cutting and overlaying steps. Its advantages are high utilization rate of material, low cost, uniform density, and high productivity.

Description

1. Technical field [0001] The invention relates to the technical field of brake discs, in particular to a method for manufacturing a carbon / carbon composite material brake disc. 2. Background technology [0002] At present, carbon cloth, needle-punched carbon felt, needle-punched carbon fiber, etc. are used as brake disc matrix materials. The original form of these materials is roll material or square, which needs to be cut and laminated during use. Clamping devices are required in the production process of carbon brake discs. Therefore, the current production method of brake disc substrate has the disadvantages of low material utilization rate, low production efficiency, high production cost, complicated process, high labor intensity and harsh working environment. 3. Contents of the invention [0003] The object of the present invention is to provide a carbon / carbon composite material brake disc manufacturing method with high material utilization rate, high production eff...
