(Summary description)Generally not. The melting point of conventional polypropylene non-woven fabric is 160 ~ 170 ℃; and that of polyester non-woven fabric is about 260 ℃.However, there is a material that is made of acrylic fiber, viscose fiber or asphalt fiber by needle punching method, after oxidation treatment and carbonization treatment and then graphitization, the carbon felt is made of high temperature resistance up to 3000 ℃, The coefficient of thermal expansion is less than (2 ~ 5) * 10-6 / ℃, the strength is 3 times that of aluminum alloy, and the weight is only 1/5 of that of steel. This material is used in aerospace, spacecraft, rocket nose cone, tail exhaust In the protective layer inside the tube and the large scale integrated circuit.
