Abstract
The present invention describes various methods for manufacturing gel composite sheets using segmented fiber or foam reinforcements and gel precursors. Additionally, rigid panels manufactured from the resulting gel composites are also described. The gel composites are relatively flexible enough to be wound and when unwound, can be stretched flat and made into rigid panels using adhesives.
Claims25
A reinforced aerogel composite sheet comprising:
- an aerogel, and a segmented reinforcement material sheet that comprises a fiber reinforcement, wherein the segmented reinforcement material sheet:
- has a length, a width shorter than the length, and a thickness;
- is segmented by discontinuities across the width, the discontinuities defining segments of the segmented reinforcement material sheet;
- a face sheet in contact with the segmented reinforcement material sheet, wherein the segments of the segmented reinforcement material are connected together by the face sheet;
- and
- wherein:
- a distance between adjacent discontinuities increases along the length of the segmented reinforcement material sheet.
