Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.

A 3D object according to the invention involves substrate layers infiltrated by a hardened material. The 3D object may be fabricated by a method comprising the following steps: Flatten a substrate layer. Position powder on all or part of a substrate layer. Repeat this step for the remaining substrate layers. Stack the substrate layers. Transform the powder into a substance that flows and subsequently hardens into the hardened material. The hardened material solidifies in a spatial pattern that infiltrates positive regions in the substrate layers and does not infiltrate negative regions in the substrate layers. In a preferred embodiment, the substrate is carbon fiber and excess substrate is removed by abrasion.

A method is provided for forming a flexible fire-resistant and thermal resistant sheet product. Such a method comprises securing a first insulation material sheet to a first cover sheet to form a first sheet product portion including a perimeter; securing a second insulation material sheet to a second cover sheet to form a second sheet product portion including a perimeter; and securing the first sheet product portion to the second sheet product portion, at least about the perimeters thereof and such that the first insulation material sheet is disposed adjacent to the second insulation material sheet, to form the sheet product. An associated apparatus is also provided.

A composite production method includes impregnating a plate-shaped porous inorganic structure and a fibrous inorganic material with a metal while the fibrous inorganic material is arranged to be adjacent to the porous inorganic structure.
