A cold protection material includes an outer fabric, an inner fabric, two connecting members bonded to the outer fabric and the inner fabric to form a space between the outer fabric and the inner fabric, and a filler stored in the space. Each of the two connecting members has an outer surface bonded to the outer fabric and an inner surface bonded to the inner fabric, and has air permeability, and each of the two connecting members is formed of a flexible material, and is soft enough not to be deformed to reduce a distance between the outer surface and the inner surface by a weight of the outer fabric or the inner fabric.

A method of processing ultra high hardness steel is provided to increase its usefulness in armor applications. The method involves slowly cooling the ultra high hardness steel to a cryogenic temperature, slowly returning the steel to an ambient temperature, slowly heating the steel, and again slowly returning it to an ambient temperature.

A method for manufacturing a sandwich component includes applying at least one matrix material to the upper side and/or the underside of at least one material blank, and arranging the material blanks above one another and/or next to one another. At least two of the material blanks differ in design or matrix material may be applied in different ways along the upper side and/or underside thereof, or matrix material is applied in different ways to at least one of the material blanks along the upper side and/or underside thereof. In that way, at least one horizontal and/or vertical zone of the sandwich component is created having different mechanical properties than other regions of the sandwich component. The material blanks are then pressed to form the sandwich component.

A method for manufacturing a panel including a reinforcement sheet having the steps of: providing a first layer of thermoplastic material, providing a reinforcement sheet, laying the reinforcement sheet and the first layer onto each other, applying a second layer of thermoplastic material on top of the reinforcement sheet at a side facing away from the first layer, at least partially melting the thermoplastic materials of the first layer and the second layer, adhering the at least partially melted first layer, the at least partially melted second layer and the reinforcement sheet to each other so as to form the panel. Additionally, the reinforcement sheet and the first layer are adhered to each other by pressing them together after at least partially melting the thermoplastic material of the first layer, but before applying the second layer of thermoplastic material onto the reinforcement sheet.

There is disclosed a multi-layer insulation material, comprising a sheet or a blanket including a plurality of alternating layers of insulating materials, coated with foil, wherein the multi-layer insulation material is embedded with meta-materials and wherein outer layers of the multi-insulation material comprise of polyimide. A method of manufacturing a meta-material embedded fabric is also disclosed, the method including embedding borophene and hybrids of borophene with a two dimensional (2D) material; integrating borophene or plumbene hybrid flakes under an inert ambience with the 2D material; synthesizing the embedded borophene and hybrids of borophene using a sono-chemical technique; and reducing the synthesized borophene and hybrids of borophene using a blended reaction protocol, thereby forming the meta-material embedded fabric.

Structural panels and methods of making composite material for such structural panels may include applying a resin to a nonwoven fibrous web, where the nonwoven fibrous web includes a combination of glass fibers and polymer fibers. The web may be dried at a first stage temperature at or below a curing temperature of the resin for a time sufficient to substantially dry but not substantially cure the resin. The web may be laminated at a second stage temperature sufficient to fully cure the resin to produce a composite material. The second stage temperature may be above the melting point of the polymer fibers, and the resin may cause the composite material to retain a substantially rigid shape upon completion of the laminating operation.
