    • Claim:
      1. An aerogel blanket insulator, comprising: an aerogel blanket formed to include aerogel particles, a sewing thread used to quilt the whole aerogel blanket, and a cover layer covering the surface of the aerogel blanket, wherein the aerogel blanket insulator includes the aerogel blanket made of insulation of an elastic member and the sewing thread is created to quilt only the aerogel blanket.
    • Claim:
      2. The aerogel blanket insulator according to claim 1, further comprising a separate enveloping layer that covers the above cover layer, wherein the elastic member is equipped in the form of cotton.
    • Claim:
      3. The aerogel blanket insulator according to claim 1, wherein the cover layer is formed by penetrating a liquid synthetic resin through a partial thickness of the aerogel blanket, the cover layer is formed by applying liquid polyimide or synthetic resin to the surface of the aerogel blanket, or by combining non-woven fabric or thin fabric on the layer composed of the liquid polyimide or synthetic resin again, and the sewing thread created using impregnated liquid polyimide or synthetic resin.
    • Claim:
      4. A functional composite with the aerogel blanket insulator of claim 1, comprising: an additional planar heating element layer on the cover layer on a single side of the aerogel blanket.
    • Claim:
      5. The functional composite according to claim 4, wherein the planar heating element layer includes a resistive conductive layer that generates heat when current flows, and the resistive conductive layer is formed to cover the entire surface or according to a pattern of the material or formation by either attachment, printing, or coating according to a specific pattern.
    • Claim:
      6. The functional composite according to claim 4, wherein the planar heating element is composed of a metal thin film or formed by applying and drying a viscous liquid with conductive particles or fibers, and the planar heating element forms a sewing thread on a single side as a conductive resistor while using a separate sewing thread on the top and bottom of the aerogel blanket.
    • Claim:
      7. The functional composite according to claim 4, wherein the planar heating element is formed by distributing at least two electrical terminals in multiple locations, and the planar heating element is a functional composite with a unique feature of the formation using PTC heaters made at least in part from PTC (positive temperature coefficient) materials.
