Sterilizable multilayer material (1), in particular for packaging at least one device for medical use, comprising a non-thermofusible sheet (2) sandwiched between two lower and upper thicknesses (3, 4) of thermofusible material of at least one thermofusible sheet (F), these thicknesses of thermofusible material being welded together across the non-thermofusible sheet.

The patch product comprises a membrane substrate suitable to be absorbed by the skin and based on natural polymers, as well as at least one active ingredient. It can be packaged in a wrapping comprising a support base, on which the patch product is placed, and a coating layer that acts as protection for the patch product.

The present disclosure generally relates to systems and methods for composites, including short-fiber films and other composites. In certain aspects, composites comprising a plurality of aligned fibers are provided. The fibers may be substantially aligned, and may be present at relatively high densities within the composite. For example, the composite may include substantially aligned carbon fibers embedded within a thermoplastic substrate. The composites may be prepared, in some aspects, by dispersing fibers by neutralizing the electrostatic interactions between the fibers, for example using aqueous liquids containing the fibers that are able to neutralize the electrostatic interactions that typically occur between the fibers. The liquids may be applied to a substrate, and the fibers may be aligned using techniques such as shear flow and/or magnetism. Other aspects are generally directed to methods of using such composites, kits including such composites, or the like.

A composite material structure includes a first fiber layer, a second fiber layer, and a third fiber layer. The first fiber layer is composed of a first long fiber and a first resin material. The second fiber layer is composed of a second long fiber and a second resin material. The third fiber layer is disposed between the first fiber layer and the second fiber layer. The third fiber layer is composed of a short fiber and a third resin material. A length of the first long fiber and a length of the second long fiber are both greater than a length of the short fiber, and the length of the short fiber is less than or equal to 25 mm.

Moulded three-dimensional noise attenuating trim part for a vehicle, comprising at least a three layer system consisting of a first porous fibrous layer and a second porous fibrous layer and an air permeable intermediate film layer situated between the first and second porous fibrous layers and wherein the adjacent surfaces within the three layer system are interconnected, wherein the second porous fibrous layer has an area weight AW2 that is varying over the surface and wherein at least for areas of the three layer system with a total thickness t between 5 and 35 mm, the area weight AW2 relates to the total thickness t of the three layer system as following 25*t+175<AW2<45*t+475 wherein t is in mm and AW2 is in g.Math.m−2 and wherein the area weight AW2 of the second porous fibrous layer is increasing with increasing total thickness t of the three layer system.

A process for in-line extrusion of polymeric coatings onto roofing shingles during manufacturing includes moving a web of shingle substrate material in a downstream direction and extruding a liquefied coating of polymeric material onto at least one surface of the moving web to form a thin film. The liquefied coating may be a molten polymeric material that forms a thin film on a back surface of the shingle material to prevent sticking and eliminate the need for a traditional back dusting with material such as powdered stone. The polymeric film further may be applied to the substrate material in lieu of a saturation coating of asphalt, thus reducing cost and weight while providing a comparable moisture barrier and a lighter more flexible shingle.

A composite structure is disclosed forming part of a wall of a liquid hydrogen tank, and including at least one thermal protection device having one or more of hollow fibers, such as to create thermal protection, for example a thermal barrier or a heat exchanger, which makes it possible to protect the composite structure in case of a high temperature gradient between the two faces thereof, while benefiting from the advantages of a composite material in terms of mass.

The presently disclosed subject matter is generally directed to packaging film and packages constructed from water-dispersible and/or biodegradable material. The water-dispersible and biodegradable package consists of a first layer of a water-dispersible material constituting an interior of the package, and a second layer of a biodegradable material constituting the exterior of the package. The package may have printed indicium printed onto the exterior of the package.

A traction mat wherein the foam is reinforced with a layer of fabric or fiber between the CLCC foam layer and the substrate or underlying surface. The layering is preferably a first foam layer and a fabric layer impregnated with a pressure sensitive adhesive. This prevents the CLCC foam from being bonded directly to the substrate and allows the fabric/fiber to support the CLCC foam such that the entire assembly can be removed in one piece without the CLCC foam disintegrating. The introduction of the reinforcing fabric and/or fiber layer eliminates any residual CLCC foam from being bonded to the substrate. Consequently, the traction mat can be easily lifted away and removed.

A composite silt fence configured for capturing pollutants in one embodiment comprises a silt fence fabric including i) a polymeric geotextile fabric particulate filtering layer defining the hydraulic flow capacity for the silt fence, ii) a pollutant capturing layer coupled to the polymeric geotextile fabric particulate filtering layer and configured to capture some select pollutants in water from flow that has passed through the polymeric geotextile fabric particulate filtering layer, and iii) a backing layer coupled to the pollutant capturing layer; and a plurality of stakes secured to the silt fence fabric at spaced locations. The silt fence fabric yields higher hydraulic flow than existing fence constructions with greater sediment retention and pollutant containment features.
