A vacuum heat-insulation material includes: at least one first fiber member; at least one second member that is placed around an outer peripheral part of the at least one first fiber member and that is thinner than an inner part; and at least one shell material that surrounds the at least one first fiber member and the at least one second fiber member.

A method of producing a composite material molded article includes enclosing a core fiber base material formed from unwoven fabric in a molding tool with the core fiber base material placed between a first reinforcing fiber base material and a second reinforcing fiber base material, injecting matrix resin into the first and second reinforcing fiber base materials in the molding tool, and injecting foamable resin into the core fiber base material in the molding tool.

Prepregs, composites and articles comprising expandable graphite materials dispersed in a thermoplastic layer are described. In some instances, articles that can be used in an as-produced state may provide a desired sound absorption coefficient or a desired flame spread index, e.g., less than or equal to 25 as tested by ASTM E84 dated 2009. Methods of producing the articles are also described.

A burnthrough protection system including a fire protection laminate and a foam insulation material, wherein the fire protection laminate includes a fire barrier layer and a buffer layer, the buffer layer being disposed between the fire-barrier layer and the foam insulation material, wherein the buffer layer is adapted to prevent adhesion between the fire barrier layer and the foam insulation at elevated temperature. The burnthrough protection system may be capable of passing the flame propagation and burnthrough resistance test protocols of 14 C.F.R. 25.856(a) and (b), Appendix F, Parts VI and VII. Also, an aircraft including an exterior skin, an interior liner, and the burnthrough protection system disposed between the exterior skin and the interior liner.

Panels for coupling stone or brick units to a wall structure are disclosed herein. The panels can include an expanded polystyrene foam having a plurality of laterally extending channels formed on one or more of a first and second side of the panel. The channels can aid in adhering a plurality of stone or brick units to the panel. The width of the channels can be less than the width of the stone or brick units such that the stone or brick units are disposed outside the channels when coupled to the panel.

Composite door systems that are configured for providing safety, security, and resistance to physical impacts or threats (natural and man-caused), and which can be utilized in barrier structures, such as for doors. The composite door systems may include one or more layers, each of which may have one or more fiber layers, such as fabric layers or plastic layers. The composite door systems may further include one or more additional layers of a sheet material, a fill material, or the like. The composite door systems are infinitely customizable and configured to be adapted to a variety of applications, and scalable levels of protection.

A barrier and method of manufacture thereof is provided. The barrier is suitable for enhancing the reaction to fire of structural elements such as construction boards.

A molding based on a monolithic organic aerogel has a density in the range from 60 to 300 kg/m.sup.3 and a thermal conductivity in the range from 12 to 17.8 mW/m*K. The molding based on a monolithic organic aerogel has more than 30 vol.-% of pores with a diameter of less than 150 nm, and more than 20 vol.-% of pores with a diameter of less than 27 nm, based on the total pore volume. A process can be used to prepare the molding by compression.
