Abstract
Embodiments of the present invention describe secured fiber-reinforced aerogels and laminate structures formed therefrom. In one embodiment a laminate comprises at least one fiber-reinforced aerogel layer adjacent to at least one layer of fiber containing material wherein fibers from said at least one fiber-reinforced aerogel layer are interlaced with fibers of said at least one fiber-containing material. In another embodiment a laminate comprises at least two adjacent fiber-reinforced aerogel layers wherein fibers from at least one fiber-reinforced aerogel layer are interlaced with fibers of an adjacent fiber-reinforced aerogel layer.
Claims8
A composite comprising
- a first preformed fiber-containing aerogel layer comprising a first fiber reinforcement and a first monolithic aerogel matrix;
- a second preformed fiber-containing aerogel layer separate from the first preformed fiber-containing aerogel layer, the second preformed fiber-containing aerogel layer comprising a second fiber reinforcement and a second monolithic aerogel matrix;
- and
- a plurality of tacking sites at an interface between the first and second preformed fiber-containing aerogel layers comprising fibers of the first preformed fiber-containing aerogel layer interlaced with fibers of the second preformed fiber-containing aerogel layer as Z-fibers wherein:
- the plurality of tacking sites further comprise local disruptions to the first monolithic aerogel matrix and the second monolithic aerogel matrix;
- and
- the plurality of tacking sites connect the first preformed fiber-containing aerogel layer and the second preformed fiber-containing aerogel layer.
