Abstract:
A composite includes an aerogel material with an interpenetrating fibrous structure, and a polymer coating on the aerogel material. Preparing the composite involves: incorporating a fibrous structure within an aerogel material thereby forming a composite; and coating a side of the composite with a polymeric material. Pre-coating steps include plasma and corona treatments while post-coating steps include curing, drying or sintering. Various coating methods can be used, including using an aqueous-based coating.
Abstract:
A convertible fabric (10) having improved acoustical and heat transfer properties comprising an elastomeric polymer coating (22) on a double woven fabric (10). The double woven fabric (10) having the standard sateen weave (18) and the backing fabric of a plain weave (20) interconnected to the sateen weave fabric (18) with one surface of the plain weave (20) coated with an elastomeric polymer (22) to provide air spaces between the fabrics of the double woven fabric (10).
Abstract:
A unitary composite headliner adapted to be installed adjacent a motor vehicle roof comprises at least two reinforcing layers (18, 20) of recyclable polyester fibers configured to provide sufficient flexibility to the headliner to facilitate installation in the vehicle, while also providing sufficient rigidity to the headliner to enable the headliner to be self-supporting once installed in the vehicle. The headliner further comprises at least one inner layer (16) of recyclable polyester fibers sandwiched between at least two of the reinforcing layers (18, 20) and configured to absorb sound and vibrations, and a cover member (22) of polyester bonded to one of the reinforcing layers with a polyester adhesive. The inner and reinforcing layers are bonded together by differentially heating each layer to a predetermined temperature and compressing the layers together. Furthermore, the headliner is recyclable as a unit. A method of making the headliner is also disclosed.
Abstract:
Die vorliegende Anmeldung betrifft in einem ersten Aspekt ein Verfahren zur Herstellung von schalldämpfenden, schallschluckenden und/oder isolierenden Formmaterial. Genauer betrifft das erfindungsgemässe Verfahren eines zur Herstellung dieser Formmaterialien, wobei das Fasermaterial um mindestens zwei Träger gewickelt wird und anschliessend der so erhaltene Wickelrohling auf den Trägern verbleibend weiter in sich dauerhaft verfestigt wird, um das erfindungsgemässe Formmaterial zu erhalten. In einem weiteren Aspekt richtet sich die vorliegende Anmeldung auf das so erhaltene Formmaterial, insbesondere in Form von Formmatten oder Formkörpern. Dieses Formmaterial kann insbesondere in Schalldämpfern eingesetzt werden. Schliesslich richtet sich die folgende Anmeldung auf eine Vorrichtung zum Herstellen dieser Formmaterialien aus Fasermaterial.
Abstract:
The invention relates to a sound-proofing component, particularly for absorbing noise in motor vehicles, comprising a first layer which is made of a nonwoven material, is embodied in a planar manner similar to a mat, and is provided with two opposite surfaces (4, 5). A thin spray coating (3) made of a duroplast, such as polyurethane and/or thermoplastic materials, is disposed on one of the outer surfaces (4, 5) of the nonwoven fabric (2). Also disclosed is a method for producing said component.
Abstract:
The present invention relates to an insulating material comprising continuous filaments of a synthetic material characterised in that the filaments have a mean diameter of from 4 to 20 microns and in that the filaments have been separated by a stretching and subsequent relaxation of a crimped tow of said filaments.
Abstract:
A sound absorbing material having a homogenous mixture of an organic man-made fiber, an inorganic man-made fiber, a co-binder, and a cellulose material wherein the organic man-made fiber is polyester, the inorganic man-made fiber is fiberglass, and he co-binder is a thermo-setting resin. The cellulose material may include Kaolin clay and/or boric acid.
Abstract:

Abstract:
The invention concerns a heat and/or sound insulation product based on mineral wool such as glass wool or rock wool. Said product has at least part of its outer surface uncoated. It is treated at the surface over at least a portion of said outer surface with a composition with softening properties comprising at least a surfactant. The invention also concerns the device and the method for making such a product.
Abstract:
A sound absorbing and heat insulating material which comprises carbon fiber as its constituent material and which is excellent in durability and compression recovering property, lightweight and excellent in safety against fires and non-electric corrosion. The sound absorbing and heat insulating material is one in which fibers of cotton-like carbon fiber aggregate composed of carbon fibers having an average diameter of 0.5 to 5 mu m and an average fiber length of 1 to 15 mm are bonded by a thermosetting resin. A galvanic cell comprising the sound absorbing and heat insulating material as one of electrodes, an aluminum plate as the other of electrodes, and an electrolyte, which comprises a water solution having sodium chloride of 0.45 weight %, has a galvanic current of 10 mu A or less.
