A thermal barrier material is disclosed for applications such as heat shields in automobiles and other vehicles. The thermal barrier material is made on a Fordenier paper making machine from a slurry that is very low in organic compounds that can cause smoke and odor when exposed to high temperatures. A first thermal barrier material is disclosed that can withstand up to 650°C and a second thermal barrier material is disclosed that can withstand up to 1000°C, in each case, the barrier material withstands it max temperature specification while producing extremely iow quantities of smoke and extremely low levels of offensive odors. Prior art thermal barrier materials with similar temperature specifications on the other hand produce many times the smoke and offensive odors at the same temperatures and do so for a far longer time.
A laminate gasket (10) for sealing between two opposing surfaces includes a core layer (20) formed from a sheet of woven material (30) having a first surface (34), a second surface (38) opposite the first surface (34), and a binder material (40) impregnating the sheet and at least partially coating both of the first and second surfaces (34, 38). The laminate gasket (10) also includes a first facing layer (50) adhered to the first surface (34) with the cured binder material (40) and a second facing layer (60) adhered to the second surface (38) with the cured binder material (40) to form a laminate base sheet (70), with each of the first facing layer (50) and the second facing layer (60) comprising a fiber composite material. The laminate gasket (10) further includes one or more process apertures (74) formed through the laminate base sheet and an edge seal (80) formed around an inner edge (76) of the process aperture (74) to prevent interstitial leakage of the process fluid into the core layer (20).

The sleeve (140, 260) further includes a self-protective oxide undercoat layer (143, 263) that protects the metallic material and a lubricous overcoat layer (145, 265) that provides lubricity to the contact surfaces (149, 279) when the sleeve (140, 260) is exposed to temperatures greater than about 600 °C.
An insulating container (10) for controlling the transfer of heat from a hot object contained therein, the insulating container including a first half-shell (20) and a second half-shell (21) configured to couple together to form a sealed enclosure. The container further includes a first insert (40) and a second insert (41) sized and shaped to be received within the first half shell (20) and the second half shell, (21 ) respectively, and having inner surfaces (42, 43) that are shaped to surround and substantially conform to the hot object enclosed within the sealed enclosure, and wherein the first insert (40) and the second insert (41 ) are built up from a plurality of planar pieces (50) of insulating material.

A method of making a lightweight thermal shield (902) that includes obtaining a mold (950) having a shaped support screen (960) with a molding surface configured to allow the passage of air and moisture therethrough, and with the mold (950) being adapted for drawing a vacuum (972) from behind the support screen (960). The method also includes applying a wet insulation material onto the molding surface of the support screen (960) and drawing a vacuum (972) to withdraw moisture through the support screen (960) and consolidate a layer of insulation material (93) on top the molding surface. The method further includes removing the consolidated layer of insulation material (933) from off the molding surface, installing the consolidated layer of insulation material (933) into an outer shell layer (920), and drying the consolidated layer of insulation material (933) within the outer shell layer (920) to form a lightweight core insulation layer (930).
