A thermal insulation device includes a first plate, a second plate formed to nest adjacent the first plate with a gap between the first and second plates, a porous material disposed between the plates, and a sealing layer disposed between the first and second plates such that the porous material is sealed from ambient at a pressure less than ambient. Multiple such sets of plates may be used to form an enclosure for a device that thermally insulates the device from ambient.

In some examples, an additive manufacturing technique for forming a vacuum insulator. For example, a method including forming an article including a first layer, a second layer, and at least one support member extending between the first and second layer by depositing a filament via a filament delivery device, wherein the filament includes a sacrificial binder and a powder, and wherein the first layer, second layer, and at least one support member define an open cavity within the article; removing the binder; and sintering the article to form the vacuum insulator, wherein the vacuum insulator defines a vacuum environment in the cavity.

A thermal vacuum insulation element (10) comprising a first planar limiting part (12) and a second planar limiting part (14). The limiting parts are spaced apart from each other and define an evacuated space (16) between them. The evacuated space (16) is sealed by means (26) for sealing. The vacuum insulation element includes first support elements (18) extending away from the first limiting part (12) into the evacuated space (16) and second support elements (20) extending away from the second limiting part (14) into the evacuated space (16), the limiting parts (12, 14) being arranged with the support elements (18, 20) such that the first support elements (18) and the second support elements (20) protrude beyond and are spaced from each other. The first support elements (18) are spaced from the second limiting part (14), and the second support elements (20) are spaced from the first limiting part (12). A fiber structure (22) interconnects the first support elements (18) and the second support elements (20). The fiber structure (22) has a low thermal conductivity and is configured to absorb at least the pressure caused by the vacuum on the first and second limiting parts (12, 14).

A hose is provided capable of meeting fireproof requirements per AS1055 under no flow condition. The hose has multiple layers including a yttria-stabilized zirconia (YSZ) flexible ceramic substrate layer disposed between first and second silicone rubber layers.

Aerogel-based components and systems for electric vehicle thermal management are provided. Exemplary embodiments include a heat control member. The heat control member can include reinforced aerogel compositions that are durable and easy to handle, have favorable performance for use as heat control members and thermal barriers for batteries, have favorable insulation properties, and have favorable reaction to fire, combustion and flame-resistance properties. Also provided are methods of preparing or manufacturing such reinforced aerogel compositions. In certain embodiments, the composition has a silica-based aerogel framework reinforced with a fiber and including one or more opacifying additives.

A thermal protection systems of a deployable aerodynamic decelerators includes a high temperature flexible insulation that utilizes a Flexible Gas Barrier (FGB) configured on an outside layer of a Hypersonic Inflatable Aerodynamic Decelerator-Thermal Protective System (HIAD F-TPS). The high temperature flexible insulation includes high temperature fibers and frits that melt upon exposure to elevated temperatures to prevent advection through the thickness of the high temperature flexible insulation. A coating may also be configured on an outside surface of the high temperature flexible insulation to also prevent advection. The frits may be configured through the thickness with different melting temperatures.

A thermal insulation device includes a first plate, a second plate formed to nest adjacent the first plate with a gap between the first and second plates, a porous material disposed between the plates, and a sealing layer disposed between the first and second plates such that the porous material is sealed from ambient at a pressure less than ambient. Multiple such sets of plates may be used to form an enclosure for a device that thermally insulates the device from ambient.

A breathable, multi-layer exhaust insulation system is provided. The system includes a multi-layer sleeve, wherein the first layer, which is positioned adjacent the exhaust system pipes, is a braided sleeve which may be constructed from high-temperature resistant materials such as e-glass, s-glass, silica or ceramic. Additional braided layers of material may be included, as well. An outside cover of material is preferably a circular knitted fabric that contains glass fibers and resin-based fibers. The knitted fabric forms a tube on the outside of the insulating layers, and may be formed from a core spun yarn, which includes a glass filament core and a high-melt fiber on the wrap. Optionally, the system may also include a perforated or unperforated metal foil layer and/or a tape wrap, and the various components may be configured as desired.

A sheet of material is crumpled and flattened so that it is longitudinally compressed while remaining substantially uncompressed in the lateral direction. Once so formed, the sheet may be stretched to conform to complex three-dimensional shapes. When applied to thermally insulated piping, for example, such sheets may serve as barriers to the movement of water in the insulation system.

Exhaust insulation systems and methods are described that include multiple layers. In one example, a system includes a base insulation layer covering a portion of an exhaust pipe and a hard outer cover formed from a spirally wrapped knit tape and having a length coextensive with the length of the underlying base insulation layer. The wrapped knit tape outer cover can include successive turns of tape overlapping by 25% to 75%. The knit tape can be impregnated with a thermosetting phenolic resin prior to being wrapped about the pipe.
