Generally not. The melting point of conventional polypropylene non-woven fabric is 160 ~ 170 ℃; while the non-woven polypropylene fabric is about 260 ℃.
But there is a kind of carbon felt made of acrylic fiber, viscose fiber or pitch fiber by needle punching, carbonization treatment after oxidation treatment and carbonization treatment, and high temperature resistance can reach more than 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 steel. This material is used for aerospace, spacecraft, rocket cone, tail exhaust of aircraft Tube inner protective layer and large scale integrated circuit.
