A sheetlike composite material including at least one layer A of a nonwoven thermoplastic fiber web or a thermoplastic film, and at least two unidirectional oriented-fiber layers B and B′, the layers B and B′ having a bidirectional fiber orientation. The layers are not only needled but also stitched to one another.

A coating of structures or elements or parts made of plastic material obtained by molding includes a finish layer; a reinforcement layer coupled to the finish layer, from the opposite side to the exposed face, to form a sandwich; and a heat-sealable film coupled in its solid form to the reinforcing layer, wherein this sandwich is suited to be coupled to a support part in a plastic material obtained by molding, and wherein this coupling occurs during the molding of the support part by way of the heat-sealable film suited to be activated at the molding temperature.

Separating membrane of plastic material, made up of a bossed and waterproof sheet which is coupled with a permeable base layer. The bosses are of the cylindrical type with a double diameter and have such a shape and arrangement as to feature improved adhesion on both faces. The gripping of the adhesive is increased in order to obtain greater tear strength, on the upper face, and at the same time increases the area of contact with the base layer for a greater resistance to delamination on the lower face. In particular, inside each chamber there is an internal crown, which divides it like a necking into two superimposed compartments having the same diameter, wherein the first compartment has a depth amounting to at least ⅓ of the total. A production process for obtaining the membrane is also disclosed.

A composite material provided in the form of a sheet material includes at least one textile layer as a cover for an airbag. The cover is arranged to form at least one flap with a hinge which includes a hinge region. One side or both sides of the at least one textile layer includes a plastics coating. A melting point of the plastics coating is lower than a melting point of the at least one textile layer. The hinge region is arranged to form at least one single or double fold along the hinge so that the sheet material contacts itself once or twice. In a region of the at least one single or double fold, areas of the plastics coating are arranged to contact each other and, via a prior introduction of heat or a subsequent introduction of heat, are melted onto each other.

There are provided rolls comprising an air and water barrier article having opposing first and second major surfaces, a pressure sensitive adhesive disposed on at least the first major surface of the article, and a liner having a first major surface that contacts the opposing second major surface of the article, and at least two adhesion modifying zones disposed between the second major surface of the article and the first major surface of the liner, wherein both of a first and second adhesion modifying zones contact the first major surface of the liner, and wherein the pressure sensitive adhesive contacts a second major surface of the liner when wound in the roll. There are also provided films made using these air and water barrier articles and building envelopes made using such films.

An acoustic material comprising one or more acoustic composite layers; and a facing layer, wherein the one or more acoustic composite layers are formed of a nonwoven sound absorption material; wherein the facing layer is permeable; and wherein the facing layer is attached to a top surface of the one or more acoustic composite layers. The facing layer may optionally include metallic components or a metallized outer surface. The acoustic material may optionally include a pressure sensitive adhesive material on an opposing side of the one or more acoustic composite Sayers to enable installation of the acoustic material. The facing layer may include a permeable scrim, a perforated film, or a perforated foil. The facing layer may be metalized on its top exposed surface to provide infrared heat reflection, and a corrosion resistant coating may be applied on top of the metalized layer if required to stabilize the metal coating.
