Abstract: The invention relates to a textile material in sheet form, consisting of a warp and weft fabric produced by rovings of continuous technical filaments (glass, carbon, aramide) without torsion. The invention is characterized in that the fabric is produced according to a plain weave or derivative thereof, the density of the warp (C) and the weft (T) being balanced; the warp threads (C) or weft threads (T) are weakened or cut individually at predetermined intervals without any noticeable deterioration in the characteristics of the weft or warp threads situated beneath the weakening or cutting area; and the areas in which a series of threads of the fabric (C) or (T) are weakened or cut are produced with a lateral and vertical thread course between two consecutive threads.

Abstract: 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.

Abstract: A unidirectional textile reinforcement fabric for use in laminated articles and a method of making such fabric from conventional warp and weft fabric is shown in which the filament bundles in one of either warp or weft are substantially broken with little or no damage to the other.

Abstract: This invention relates to a novel type of textile reinforcement adapted to be used for making laminated complexes, of the type constituted by at least one layer of reinforcing yarns. The yarns are bonded together by adhesion with binding yarns, disposed transversely, in a small proportion with respect to the reinforcing yarns.Reinforcing yarns are spaced apart from one another so as to form stable and undeformable holes of definite shape.Additional binding yarns are disposed on either side of each of the strips of reinforcing yarns.

Abstract: The present invention relates to a material which may be used as reinforcement for bituminous impermeable coverings of the type constituted by a non-woven fibrous lap. The material being characterized in that the lap is formed by a complex comprising an intermediate layer constituted by a non-woven fabric of polyester. The non-woven fabric serving as a support for glass fibers implanted in its thickness. The fibers project on each side of said support and are folded back thereon.
