The need for improved coatings on low‐density reusable surface insulation (RSI) materials used on the space shuttle has stimulated research into developing tougher coatings. The processing of a new porous composite “coating” for RSI called toughened unipiece fibrous insulation is diseassed. Characteristics including performance in a simulated high‐speed atmospheric entry, morphological structure before and after this exposure, resistance to impact, and thermal response to a typical heat pulse are described. It is shown that this coating has improved impact resistance while maintaining optical and thermal properties comparable to the previously available reaction‐cured glass coating.
