Abstract
Improved processes are provided for treating a porous substrate (especially a fabric) to produce novel internally coated porous materials. During treatment, a curable thixotropic material and one or modifying materials are applied to the porous substrate as an impregnant. The treatment imparts specific properties to the end product material. Selection of the modifier material is based on the particular end use application. Sufficient energy is directed to the impregnant and porous substrate to cause the impregnant to flow into the porous substrate and force the modifier to specific positions within the substrate.
