A method for preparing a flexible low-density thermal protection material, the method comprising providing a flexible substrate and a pyrolizable material impregnated therein. The thermal protection material remains flexible after impregnation and continues to remain flexible when the pyrolizable material is fully pyrolized.

Method of fabricating a flexible, low-density thermal protection material

A low-density article comprising a flexible substrate and a pyrolizable material impregnated therein, methods of preparing, and devices using the article are disclosed. The pyrolizable material pyrolizes above 350 C and does not flow at temperatures below the pyrolysis temperature. The low-density article remains flexible after impregnation and continues to remain flexible when the pyrolizable material is fully pyrolized.
