Abstract (en)
[origin: US5175042A] Textile composite comprising at least two superposed nonwoven fibrous sheets (1, 2), Sheet (2) based on flexible synthetic fibers and the other sheet (1) based on inorganic fibers. Bonding of the sheets is obtained by means of a minor part (2a) of the synthetic fibers which are implanted into the thickness of the sheet (1). In the sheet (1), the fibers are oriented substantially parallel to the surface and form a relatively dense assembly, the sheet (1) being subjected, before its combination with the sheet (2), to a treatment producing fine perforations in its thickness, inside which perforations are preferably implanted the synthetic fibers (2a) which bond the sheets (1, 2) together.
