Description

Technical Field

[0001] The invention relates to the technical field of composite filter material production, in particular to an ultra-high temperature resistant carbon fiber composite filter material and a production system thereof. Background Art

[0002] Ultra-high temperature resistant carbon fiber composite filter material is a special advanced material, mainly composed of carbon fiber and resin, designed to withstand extreme temperatures and harsh environmental conditions. This type of material is known for its excellent mechanical properties and thermal stability and is widely used in fields that require high temperature filtration and separation functions.

[0003] In certain industrial applications and extreme environments, such as rocket engines, melting furnaces and other high-temperature processes, materials may be exposed to temperatures exceeding 300°C, or even extreme conditions as high as 2000°C. In this case, traditional materials often cannot meet the requirements of high temperature resistance, wear resistance and chemical stability. In the prior art, the conventional means of making carbon fiber composite filter materials is to select high-performance carbon fiber as a reinforcing material and perform surface treatment on it to enhance the bonding strength with the resin; then, the resin (such as epoxy resin or thermoplastic resin) is mixed with the carbon fiber in a certain proportion, and the resin is evenly covered on the carbon fiber by impregnation or spraying; then, hot pressing or curing treatment is performed to ensure that the resin forms a stable composite structure during the curing process; finally, after cutting and post-processing, the prepared carbon fiber composite filter material is processed into the required shape and size to meet specific application requirements, but there is still room for improvement in high temperature resistance. The performance fluctuations caused by the difference in material proportions during preparation are likely to cause the risk of material inapplicability and cause unnecessary waste.
