Brief Analysis of the Role and Application of Carbon Felt

 

Against the backdrop of accelerating global energy transformation and the in-depth implementation of the national “dual carbon” strategy, the new energy and new materials industries have ushered in a new window of development and opportunity. Against the backdrop of the strong development momentum of new energy today, the role and value of carbon felt are increasing day by day.

 

Felt made of carbon fiber is referred to as carbon felt. According to the different fiber raw materials, it can be divided into three types: polyacrylonitrile (PAN) based, asphalt based and viscose based. Let’s briefly analyze the role and application areas of carbon felt.

 

Carbon Felt is used for Thermal Insulation

 

Carbon fiber material has good heat resistance. It can withstand temperatures above 1000 degrees in inert gas and has an ignition point of up to 500 degrees in air. Therefore, many manufacturers in the industry use carbon felt as insulation material for the inner wall of high-temperature furnaces and wrap it around the furnace wall.

 

 

The Carbon Felt is made by carbonizing the raw material viscose fiber felt (PAN-based pre-oxidized felt). The felt body is treated at a temperature of 2200°C to remove impurities and increase the carbon content. It is used in the photovoltaic field.

 

 

Carbon Felt Used in Hydrogen Energy Field

Carbon Felt and carbon cloth are gas diffusion layer materials widely used in electrodes. They are key materials for fuel cells and special materials for proton exchange membrane hydrogen fuel cells. The gas diffusion layer is an indispensable material in the membrane electrode assembly (MEA), the heart of the fuel cell.

 

Carbon Felt is used in aircraft structural materials, electromagnetic shielding materials and electrical materials, as well as in the construction of rocket shells, motorboats, industrial robots, automotive leaf springs and drive shafts.

 

 

The role and application of carbon felt are supported by many national policies and meet people’s needs for low-carbon green life. Seize the opportunities of the times for the development of new materials and new energy industries and adhere to the development thinking of systematization and chain grouping.
