Abstract
Aerogel composite materials having a lofty fibrous batting reinforcement preferably in combination with one or both of individual short randomly oriented microfibers and conductive layers exhibit improved performance in one or all of flexibility, drape, durability, resistance to sintering, x-y thermal conductivity, x-y electrical conductivity, RFI-EMI attenuation, and/or burn-through resistance.
Claims51
A composite article to serve as a flexible, durable, light-weight insulation product, said article comprising a lofty fibrous batting sheet and a continuous aerogel through said batting.
A composite article comprising a fibrous batting sheet and a continuous aerogel through said batting, where the batting is sufficiently lofty that the cross-sectional area of the fibers of the batting visible in the cross-section of the composite is less than 10% of the total surface area of that cross section.
An aerogel composite article comprising (i) a fibrous batting sheet and a continuous aerogel through said batting, where the batting causes no substantial degradation of the thermal performance of the composite as compared with an aerogel of the same material and (ii) microfibers having diameters from about 0.1 to 100 μm and aspect ratios greater than 5.
An aerogel composite article comprising (i) a fibrous batting sheet and a continuous aerogel through said batting, where the batting causes no substantial degradation of the thermal performance of the composite as compared with an aerogel of the same material and (ii) one or more high thermal conductivity materials having a thermal conductivity of equal to or greater than 1 W/mK.
