Abstract:
The invention relates to a sheetlike composite comprising, as layers of a layer sequence, from an outer face of the sheetlike composite to an inner face of the sheetlike composite, a) an outer polymer layer comprising i) a polymer matrix, and ii) a multitude of inorganic particles; b) a carrier layer; c) a barrier layer; and d) an inner polymer layer; wherein the outer polymer layer superposed on the carrier layer is characterized by a reflectance for a reflection of light having a wavelength in a range from 600 to 800 nm in a range from 4% to 8%. The invention further relates to a container precursor and to a closed container comprising the sheetlike composite and to a method by which the sheetlike composite is obtainable, to a method by which a container is obtainable, and to a method by which a filled and closed container is obtainable, and to a use of the sheetlike composite.
Abstract:
A laminate structure and method of welding the laminate structure is provided. The laminate structure includes a first metal sheet having a first thickness, a second metal sheet having a second thickness, and an adhesive core made of an adhesive material also described as a viscoelastic adhesive material. The adhesive core is disposed between and bonded to the first and second metal sheets. The first and second metal sheets are made of an aluminum based material. The adhesive core includes a plurality of electrically conductive filler particles dispersed in the adhesive materials. The filler particles are made of a first filler material and at least a second filler material which is a different material than the first filler material.
Abstract:
The disclosure relates to a building panel (1) including a water resistant core (5) comprising thermoplastic material 21 and a surface layer (4) comprising thermosetting resins. Production methods to form a board material (1') with a dry blend of thermoplastic particles 21a in powder form and fillers in powder form and to apply a surface layer (4) with a hot-hot lamination process to a core (5) comprising such board material are also described.
Abstract:
The present invention relates to a double sheet aluminum panel (1) and a method for manufacture thereof. The double sheet aluminum panel consists of a first layer (2) of a first aluminum material attached to a second layer (4) of a second aluminum material. The first and second layers are attached to each other by means of an adhesive layer (3) disposed between the first and second layers (2, 4). The inventive double sheet aluminum panel is non-flammable.
Abstract:
A method for producing a low-pressure thin-walled heat exchanger and a low-pressure thin-walled heat exchanger are described. In the production process, a thin metal cover layer and a thin metal or plastic cover layer are sealed together. The seal is provided by means of a thin layer made of a sealable polymer in the form of a coating on one side of at least one cover layer, and/or by means of a separate intermediate layer made of a sealable polymer. The two cover layers are sealed together by means of the layer arranged therebetween made of the sealable polymer, forming a hollow space suitable for the passage of a heat exchange medium, which can be designed as a channel system. Such heat exchangers can be produced particularly affordably in this manner.
Abstract:
A method of preparing aluminum alloy-resin composite and an aluminum alloy-resin composite obtainable by the same are provided. A method of preparing an aluminum alloy-resin composite structure, comprising the steps of: S1: anodizing a surface of an aluminum alloy substrate to form an oxide layer on the surface, in which the oxide layer is formed with a nanopores; S2: immersing the resulting aluminum alloy substrate in step S1 in a buffer solution having a pH of about 10 to about 13, to form a corrosion pores in an outer surface of the oxide layer; S3: injection molding a resin onto the surface of the resulting aluminum alloy substrate in step S2 in a mold to obtain the aluminum alloy-resin composite.
Abstract:
Um Sandwich-Verbundelemente (100) mit einem verbesserten Brandschutzverhalten bereitzustellen, wird ein Verfahren zur kontinuierlichen Herstellung von Sandwich-Verbundelementen (100) mit einer Unterdeckschicht (10), einer Oberdeckschicht (11) und einem zwischen den Deckschichten (10, 11) eingebrachten Polyurethan- Hartschaumkernkörper (12) vorgeschlagen, wobei eine Doppelband-Transportanlage (18) mit einem Untertransportband (19) und mit einem Obertransportband (20) vorgesehen ist und wobei die Unterdeckschicht (10) und die Oberdeckschicht (11) zwischen die Transportbänder (19, 20) kontinuierlich einlaufen, wobei wenigstens eine Glasfasermatte (13) kontinuierlich zwischen die Deckschichten (10, 11) einläuft und angrenzend an die Innenseite wenigstens einer der Deckschichten (10, 11) angeordnet wird und wobei auf wenigstens eine Innenseite der Deckschichten (10, 11) und/oder auf die Glasfasermatte (13) ein anschließend aufschäumendes Reaktionsgemisch (14) zur Bildung des Polyurethan- Hartschaumkernkörpers (12) aufgebracht wird.
Abstract:
A panel stiffening element (50) comprises an outer braided thermoplastic tube (54) and an inner braided thermoplastic tube (62) disposed within the outer braided thermoplastic tube. The stiffening element has a separation ply layer (76) co-consolidated between the outer braided thermoplastic tube and the inner braided thermoplastic tube. The separation ply layer provides reinforcement and impact damage resistance to the inner braided thermoplastic tube in order to avoid a loss in structural loading capability.
