  • High strength nanoporous bodies reinforced with fibrous

    The resulting silica batting/carbon fiber/silica aerogel composite has a thermal conductivity of 14.8 mW/m-K (ASTM C-177). The flexibility of the composite is slightly less than that of the aerogel blanket of Example 2 (Blanket #2) but still significant. The aerogel matrix tends to crack in a macroscopic fashion when strained.
