Generally cannot. Conventional polypropylene non-woven melting point is 160 ~ 170 ℃; The polyester nonwoven for around 260 ℃.

But there is a kind of material is made of acrylic, viscose fiber or fiber asphalt felt up by acupuncture method, after oxidation treatment and carbonized again after graphitization processing and made of carbon felt, its resistance to high temperature can reach 3000 ℃ above, thermal expansion coefficient is less than (2 ~ 5) * 10-6 / ℃, intensity for 3 times of aluminum alloy, the weight is only 1/5 of the steel. The material used in space, spacecraft and the rocket nose cone, the aircraft tail exhaust pipe inside of the cover and large scale integrated circuits.
