The invention relates to a connection method in addition to a functional part which can be used therefor and to a flame-retardant total system produced in accordance therewith. The invention relates to a method for connecting a single- or multilayer functional part (10) to a third component (20), wherein the functional part (10) has functional elements (14, 16) projecting on at least one side. Said method is characterized in that the functional part (10) is formed at least partially from a material which is at least partially transparent to laser light, and in that a blocking layer (18) is disposed so as to be at least partially opaque to laser light in such a way that after passage of the laser light through the functional part (10) the laser light inside the blocking layer (18) generates heat by absorption which is suitable for melting the functional part (10) and/or the third component (20) in order to connect them to one another in this way.

Method for manufacturing a cell-like honeycomb structure, formed from a plurality of thermoplastic sheets attached to each other, wherein contoured areas are provided in each sheet, and each free sheet is attached to an adjacent sheet of an intermediate block formed by the different sheets previously attached therebetween, welding at least some of the flat areas contacting this free sheet and this adjacent sheet with a laser source along a continuous line parallel to the contour axis.

A water vapor permeable, waterproof textile laminate, comprising at least two layers made of planar web material, which are disposed on top of each other and bonded to each other, wherein an open fabric web comprising polymer fiber threads forms a top tier and a film-like, water vapor permeable, waterproof thermoplastic membrane web forms a bottom tier. The polymer fiber threads of the fabric web comprise raised thread regions, which are held bearing against the membrane web and/or are partially fused into the membrane web, wherein the membrane web comprises integral fusion areas with the raised thread regions, which are generated according to the invention by way of laser light in a laser transmission welding method.

The invention relates to an edge trim for pieces of furniture, comprising a meltable layer. In order to improve a generic edge trim such that the same is more versatile and can especially be mounted on a wider selection of surfaces, the molecular structure of the meltable layer contains both polar and non-polar parts.

A process for room temperature substrate bonding employs a first substrate substantially transparent to a laser wavelength is selected. A second substrate for mating at an interface with the first substrate is then selected. A transmissivity change at the interface is created and the first and second substrates are mated at the interface. The first substrate is then irradiated with a laser of the transparency wavelength substantially focused at the interface and a localized high temperature at the interface from energy supplied by the laser is created. The first and second substrates immediately adjacent the interface are softened with diffusion across the interface to fuse the substrates.

A fluidic device including an inorganic solid support attached to an organic solid support by a bonding layer, wherein the inorganic solid support has a rigid structure and wherein the bonding layer includes a material that absorbs radiation at a wavelength that is transmitted by the inorganic solid support or the organic solid support; and a channel formed by the inorganic solid support and the organic solid support, wherein the bonding layer that attaches the inorganic solid support to the organic solid support provides a seal against liquid flow. Methods for making fluidic devices, such as this, are also provided.
