ABSTRACT:
A thermal insulation composite includes at least a first metallic skin sheet, and a plurality of non-combustible metallic filaments randomly interlocked to form a wool and affixed to said first skin sheet. A second metallic skin sheet may be affixed to said wool and said first sheet, or the second skin sheet may be a surface of the structure to be insulated. A fluid is present in the interstices of the filaments and in the zone between the skin sheets. Each of the filaments has a significant length to cross-sectional diameter ratio to minimize its thermal conductivity. The filaments also preferably have a circular cross section to minimize the area of contact and hence the heat conducted between adjacent filaments. In this manner, the conductivity of the wool is made primarily dependent upon the thermal conductivity of the fluid in the interstices of the filaments. Heat transmission by radiation is inhibited by providing a plurality of radiation shields interposed between multiple layers of the wool. The skin sheets, wool, and radiation shields are bonded by stitches or staples to form an insulation blanket. The interstices of the filaments are of many different sizes so that the insulation has characteristics for absorbing sound waves over a significant band of frequencies. The composite may be used to insulate ducts, airfoil surfaces, fire walls and to form fireproof garments, and has the unique capability of being fabricated into a variety of structural shapes.
