Carbon Fiber Felt

Product features: Carbon fiber needle-punched felt is made of polyacrylonitrile-based flat felt. Firstly, the short fibers are layered by mechanical carding and other methods, and then prepared by needle punching method; it is also called carbon fiber non-woven fabric, which belongs to carbon fiber woven fabric. A sort of. It has the characteristics of light weight and softness, small specific heat capacity, good heat insulation and convenient operation.

• Resistivity (Ohm.cm): 0.18-0.22

• Carbon content (%): ≥94

• Ash content (%): ≤0.5

• Moisture absorption rate (%): ≤2

• Processing temperature (℃)):1000-1450

Specification:

• Length (m): 3-27

• Width (m): 1-1.25

• Thickness (mm): 3-15

• Applicable temperature range (℃): 1300-2800

Main application: Since 90% of the carbon felt is void, in a vacuum or inert gas high-temperature environment, it is used in various high-temperature vacuum furnace heat insulation materials, hot gas or liquid and molten metal filter materials, fuel cell porous electrodes, Catalyst carrier, corrosion-resistant container composite material lining, and can also be used as a reinforcement material for carbon/carbon composite materials.
