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.

Described herein are window retrofits including a monolithic silica aerogel slab having (i) an average haze value of <5% as calculated in accordance with ASTM standard D1003-13 and (ii) a U-factor of <0.5 BTU/sf/hr/° F., and a transparent polymer envelope sealed at an internal pressure of ≤1 atmosphere, wherein the monolithic silica aerogel slab is encapsulated in the transparent polymer envelope. The monolithic aerogel slab can have a transmittance >94% at 8 mm thickness. The window retrofit can be bonded to a glass sheet.

A vehicle component construct including a panel formed of a composite sandwich material. The composite sandwich material including an open area core defining a plurality of pores, a high gloss surface sheet adhered to a first face of the open area core by a first adhesive layer, and a structural skin adhered to a second face of the open area core by a second adhesive layer. The exterior surface of the panel being defined by the high gloss surface sheet of the composite sandwich panel material and the oppositely opposed interior surface of the panel being defined by the structural skin of the composite sandwich material. The vehicle component construct being suitable for use as a body section of a vehicle.

Building materials such as structural panels, beams, roof decking, and flooring panels, are packaged within a protective layer including a sublayer of a polymeric material that can be applied at the factory. The protective layer protects the underlying building materials from exposure to weather and potential damage due to handling during shipping, at a job site, and which can be left in place during construction, thus eliminating the need for temporary protective measures covering the building materials. The protective layer may have additional properties such as breathability, fire resistance, and sound absorption. The protective layer also may provide an underlayment such as for flooring and roofing.

Disclosed is a composite flame barrier which is developed with the aim of being used primarily in the defense industry. The barrier includes a first silicone blend layer which provides flame resistance, a carbon impregnated aerogel layer which provides lightness and thermal insulation and a second silicone blend layer which provides thermal insulation, mechanical strength and unification. A for the composite flame barrier is also disclosed.

An insulative construction product includes a polyurethane foam core and a mixture of Aerogel and carbon black that is disposed within the polyurethane foam core. The mixture of Aerogel and carbon black includes between 90 and 99 weight percent Aerogel and between 1 and 10 weight percent carbon black. The polyurethane foam core includes between 10 and 90 percent by volume of the of Aerogel and carbon black mixture and the construction product has an R-value of at least 8.0 R/inch.

A retrofitted window is disclosed which includes a substantially transparent aerogel film laminated on a glass windowpane, the aerogel film being embedded with randomly dispersed nanoparticles of vanadium dioxide (VO.sub.2) core and silicon dioxide (SiO.sub.2) shell, wherein the vanadium dioxide (VO.sub.2) core transitions between an insulator phase and a metal phase at a predetermined phase-transition temperature, and a volume fraction of the nanoparticles in the aerogel film is approximately between 0.001% and 0.05%.

The present application relates to the technical field of composite film, and more particularly, to a diaphragm composite material and a preparation method thereof. The diaphragm composite material includes a polyethylene naphthalate (PEN) film layer, an aluminum-plated film layer, an aerogel layer, and an elastic adhesive layer disposed between the PEN film layer and the aluminum-plated film layer for bonding the PEN film layer and the aluminum-plated film layer, the aerogel layer is coated on one side of the aluminum-plated film layer away from the elastic adhesive layer. The diaphragm composite layer of the present application has high strength and strong rigidity, has better vibration dampening and noise-reducing effects, and wear-resistant and corrosion-resistant effects, and is worthy of popularization.
