Disclosed is a non-flammable thermal insulating composite substrate for motor vehicles including: a textile component constituted by a layer of needle-sewn non-woven fabric composed of a percentage of pre-oxidized polyacrylonitrile fiber included between 40% and 70%, preferably 58% and of the remaining percentage of polyethylene glycol-terephthalate fiber, the textile component having weight preferably 400 gr/m.sup.2; and a barrier fixed to the textile component using a spreading process, constituted by a thermoplastic resin based on low density polyethylene added with non-halogen flame retardants, the barrier having weight preferably 100 gr/m.sup.2. The composite substrate has the following features: a thickness included between 2 mm and 5 mm, preferably 3.8 mm; a weight included between 300 gr/m.sup.2 and 700 gr/m.sup.2, preferably 500 gr/m.sup.2; odorless; no emission of fumes; dimensionally stable, even at heatstroke, with a maximum variation of 1%; and non-flammability.

A controlled shear vacuum forming method that includes forming a three-dimensional (3D) structure from a preform material on a molding tool using restraints during vacuuming to prevent wrinkling. The restraints are withdrawn during vacuuming to allowing the preform material to come into contact with the sidewalls of the molding tool in a gradual manner. Such forming method is particularly suitable for forming wing spars with bent sections and/or curved contours.

The present disclosure provides a plastic bladder for containing a liquid. The bladder includes a barrier layer and a recycled plastic layer adjacent to the barrier layer. The bladder further includes a fitting in contact with the layer.

An electrolyte conductor (1) has a nonwoven fabric (2), onto which a plastic film (3) is laminated. A process is provided for the manufacture of the electrolyte conductor (1). An electrochemical gas sensor (10) is provided with such an electrolyte conductor (1). A gas-measuring device is provided with such a gas sensor (10).

The invention is directed to a core material, suitable for use in a closed mold system, based on at least one fibrous web containing a foam-structure within the web, said foam-structure being formed of a plurality of members that are separated from each other by channels, wherein said core material has a compression-resistance of greater than 40% at a pressure of 4 bar and at a temperature that is greater than or equal to 80° C.

A fitting element for use in rehabilitation of pipelines with a liner. The fitting element is a composite article of reinforcing fibers and a resin composition. A first part of the fitting element has reinforcing fibers and a substantially fully cured resin composition, and a second part has dry reinforcing fibers that can accept a curable resin composition that optionally originates from the liner to form a functional joint between the fitting element and the liner. An interface layer of the fitting element structurally connects the first and the second part. A method for manufacturing the fitting element, as well as a method for rehabilitation of a pipeline with a tubular liner and a joined assembly of the fitting element and a liner for use in rehabilitating a pipeline.
