carbon felt and C/SiC material

Carbon fiber carbonization temperature is only more than 1 thousand degrees, the use of carbon fiber felt after the temperature is more than 1 thousand degrees. Carbon fiber in the air heated to nearly three thousand degrees into graphite fibers made of graphite fiber felt after the temperature can reach more than 2 thousand degrees. If the carbon fiber felt for the changing environment of more than 2 thousand degrees of heat preservation.
C/ SiC composites were manufactured by the process of reactive infiltration of gaseous silicon with carbon felt reinforced carbon green, which is made from viscose rayon-based carbon felt perform treated with CVD carbon and phenolic resin pyrolysis carbon. They have the advantages of high purity, high temperature resistance, corrosion resistance, non melting and so on, but also can be flexible, can be folded, cut and can be used with graphite yarn stitching and so on. In the chemical industry can be used as a filter material of high purity corrosive chemical reagents. Under the condition of non oxidizing atmosphere, the temperature of graphite felt is up to 3000C.
All in all, the carbon felt is one of the important insulation materials in our life.
