Beschreibung
Zusammenfassung:	A nonwoven composite for high temperature applications requiring Sow flammability, smoke, and/or toxicity, including a fibrous structure having one or more nonwoven material layers including a scrim layer. The scrim is formed from inorganic fibers, at least some of which are adapted to withstand temperatures of up to about 1150 °C. The scrim is formed from a wet-laying process. The composite further comprises one or more fiber matrix layers. La présente invention concerne un composite non tissé pour des applications à haute température nécessitant de faibles inflammabilité, fumée et/ou toxicité, comprenant une structure fibreuse ayant une ou plusieurs couches de matériau non tissé comprenant une couche de renfort. Le renfort est formé à partir de fibres inorganiques, dont au moins une partie sont conçues pour résister à des températures allant jusqu'à environ 1 150 °C. Le renfort est formé selon un procédé de dépôt par voie humide. Le composite comprend en outre une ou plusieurs couches de matrice de fibres.
