Flammability test in specimens of OXIDIZED PAN fibers with automotive thermoacoustic coating blanket

Resumo

Oxidized PAN fibers is a commercial material produced from the oxidation of polyacrylonitrile fibers that has flameproof characteristic and can be applied as a thermal barrier. This work aims to evaluate the effectiveness of oxidized Panblankets as flameproof barrier in automotive vehicles. For this, the Specimens were produced using material similar to the inner lining of vehicles protected by a layer of Oxidized PANblankets as a thermal barrier. The flammability test was performed according to UL-94 and CONTRAN standards. The main result was a significant reduction in the flammability of the automotive material when it had two faces covered with oxidized Pan. The results indicate the possibility of using this material, national and low cost, in the automotive industry as a security item.
