Pre-oxidized fiber felt, also known as pre-oxidized PAN (polyacrylonitrile) fiber felt, is a type of non-woven textile material made from pre-oxidized PAN fibers. PAN fibers are high-strength, high-modulus synthetic fibers that are commonly used in the manufacture of carbon fiber.

To create pre-oxidized fiber felt, the PAN fibers are first pre-oxidized, which involves heating the fibers in an oxygen-rich environment to convert them into a heat-stable state. The pre-oxidized fibers are then carded and needle-punched to create a non-woven felt fabric.

Pre-oxidized fiber felt has a number of desirable properties, including high temperature resistance, good thermal stability, and excellent chemical resistance. It is often used in high-temperature applications such as insulation in furnaces, boilers, and other industrial equipment. It can also be used as a filter medium in air and liquid filtration systems due to its high porosity and filtration efficiency.

Technical data:

Pre-oxidized fiber felt, also known as carbon fiber felt, has several advantages:

1. High temperature resistance: Pre-oxidized fiber felt can withstand high temperatures up to 2000°C, which is much higher than most other materials.
2. Excellent thermal insulation: Due to its low thermal conductivity, pre-oxidized fiber felt is an excellent thermal insulator. It can be used in high-temperature applications to prevent heat loss.
3. Chemical resistance: Pre-oxidized fiber felt is resistant to most chemicals, including acids, bases, and organic solvents. This makes it suitable for use in harsh chemical environments.
4. Lightweight: Pre-oxidized fiber felt is very lightweight, making it easy to handle and install. It is also ideal for use in applications where weight is a critical factor.
5. High strength and stiffness: Pre-oxidized fiber felt has high strength and stiffness, making it suitable for use in structural applications. It can be used to reinforce composites or as a standalone material.
6. Corrosion resistance: Pre-oxidized fiber felt is highly resistant to corrosion, making it suitable for use in corrosive environments.
7. Electrically conductive: Pre-oxidized fiber felt is electrically conductive, making it suitable for use in applications where electrical conductivity is required.

Overall, pre-oxidized fiber felt offers a unique combination of high-temperature resistance, thermal insulation, chemical resistance, lightweight, high strength and stiffness, corrosion resistance, and electrical conductivity, making it a versatile material for a wide range of applications.
