Abstract

The invention provides a brake disc prepared from a QICC carbon / carbon-SiC nano redundant composite material and a preparation method. The invention relates to a preparation technology of brake discs.In order to solve technical problems and improve defects, the invention provides a brake disc prepared from a QICC carbon / carbon-SiC nano redundant composite material and a preparation method, characterized in that nano fiber is extracted from carbon fiber to synthesize a brake disc friction material, the pore structure of the carbon fiber is changed, a sodium hydroxide solution and a sodium sulfite solution are added for processing, more uniform hollow spaces are created in the structure of a carbon-ceramic composite material by removing some compounds, and the interface of controlling the carbon-ceramic composite material is optimized by means of surface modification and in-situ synthesis, so that the brake disc has higher use temperature and more excellent abrasion resistance, intensity, toughness, mechanical properties and integrated comprehensive properties, and is suitable for industrialized production.

Description

technical field

[0001] The invention relates to a preparation process of a brake disc, in particular to a preparation method of a C / C-SiC nano redundant composite material brake disc. Background technique

[0002] The rapid development of nanotechnology has greatly promoted the development of new materials in the direction of high performance, high functionality, compounding, intelligence and low cost. In the R&D and production of composite materials, nanotechnology is used to control and optimize the interface of heterogeneous materials with different scales and structures, which provides a new opportunity for the study of strengthening and toughening composite materials. C / C-SiC carbon-ceramic composite brake discs have the advantages of light weight, excellent high-temperature friction, and wear resistance, and are widely used in industrial power equipment braking systems. More forward-looking and higher requirements to face more expectations of the market.
