Nonwoven materials on the basis of heat-resistant polymeric fibres and intertiled sealings

With the beginning of the work on the material for the thermal protection of the reusable spaceship, it was clear that the tile from silica fibers cannot be attached directly on the metal casing of the product. There were required damping substrates. Also were required a variety of layers of materials, including heat-resistant inserts for the protection of the gaps between the tiles covering. In VIAM were proposed and developed non-woven materials of polymer fibers, with all the necessary properties, from thermal stability to high inflight reliability of a space ship. The paper describes the main properties of heat-resistant polymer fibers, physical and mechanical property values of non-woven materials ATM-15, ATM-16 and ATM-19, produced from this fibers, in the as received material and after impregnating of waterproofing emulsion, with application to the surface of the additional erosion-resistant coating. As a result, the materials ATM-16 and ATM-19 were marked as ATM-16ПКП and ATM
