Laminates comprising reinforced aerogel composites
The present disclosure can provide an aerogel composite. The aerogel composite comprises at least one base layer having a top surface and a bottom surface, the base layer comprising a reinforced aerogel composition which comprises a reinforcement material and a monolithic aerogel framework, a first facing layer comprising a first facing material attached to the top surface of the base layer, and a second facing layer comprising a second facing material attached to the bottom surface of the base layer. At least a portion of the monolithic aerogel framework of the base layer extends into at least a portion of both the first facing layer and the second facing layer. The first facing material and the second facing material can each comprise or consist essentially of elastic fibers such as spandex, nylon, lycra, elastane, or combinations thereof.
1. An aerogel composite comprising:
a single base layer, the base layer having a top surface and a bottom surface, the base layer comprising a reinforced aerogel composition which comprises a reinforcement material and a monolithic aerogel framework, the reinforcement material comprising a foam reinforcement material or a fiber reinforcement material, the monolithic aerogel framework extending through at least the thickness of the base layer;
a first facing layer comprising a first facing material directly attached to the top surface of the base layer; and
a second facing layer comprising a second facing material directly attached to the bottom surface of the base layer;
wherein the first facing material and the second facing material each consist essentially of a material made from elastic fibers comprising polyurethane, nylon or a combination thereof; and
wherein the first facing layer or second facing layer is directly attached to the base layer by an adhesive.
2. The aerogel composite of claim 1 , wherein at least a portion of the monolithic aerogel framework of the base layer extends into at least a portion of both the first facing layer and the second facing layer.
3. The aerogel composite of claim 1 , wherein the adhesive is selected from the group consisting of: an aerosol adhesive, a urethane-based adhesive, an acrylate adhesive, a hot melt adhesive, an epoxy, a rubber resin adhesive; a polyurethane composite adhesive, and combinations thereof.
4. The aerogel composite of claim 1 , wherein the first facing layer and second facing layer each comprise a fluid-permeable facing material.
5. The aerogel composite of claim 1 , wherein the composite material has a thermal conductivity between 18.0 mW/m-K and 40.0 mW/m-K.
6. An article of clothing or apparel comprising the aerogel composite of claim 1 .
7. The aerogel composite of claim 1 , wherein the adhesive comprises a hot melt adhesive.
