The present invention relates to a process for laminating a first substrate, which comprises a thermoplastic polymer material surface, and wherein the first substrate preferably is a thermoplastic polymer film, to a second substrate, wherein the second substrate preferably is a non-woven or woven fabric, wherein the thermoplastic polymer material surface is activated by irradiation with a laser beam prior to laminating the two substrates to each other as well as a device for carrying out such a process.

A method of attaching a thermoplastic-based workpiece and a metal workpiece involves the use of a metal reaction coating. The metal reaction coating is applied over a base metal substrate of the metal workpiece such that the metal reaction coating faces and contacts the thermoplastic-based workpiece when the two workpieces are assembled in overlapping fashion. To attach the workpieces at their faying interface, an energy source such as, for example, a laser beam or an electric arc, is directed against the metal workpiece to create a zone of concentrated heat that at least warms up the metal reaction coating and melts a portion of the thermoplastic-based workpiece. Such heated activity at the faying interface promotes interfacial chemical bonding between the thermoplastic-based workpiece and the metal workpiece that contributes to an enhanced attachment between the workpieces.

The disclosure provides a method for the bonding of polytetrafluoroethylene sheets of various thicknesses to various surfaces. A method may include removing contaminants from a substrate for the application of the polytetrafluoroethylene sheet; applying adhesive to an etched side of the polytetrafluoroethylene sheet; and installing the polytetrafluoroethylene sheet to the substrate.

Disclosed is a method for connecting a connecting face of an edge material to a connecting face of a workpiece by a synthesis element, including the steps: of making available the workpiece, feeding the synthesis element, which is made available by at least one function film composed of an adhesive, activating the adhesive function film, applying the synthesis element to one of the connecting faces, connecting the synthesis element to the other of the connecting faces, wherein the workpiece and the edge material are connected by the synthesis element located between them. Furthermore, there is disclosed a synthesis element and a device for connecting a connecting face of an edge material to a connecting face of a workpiece.

The disclosure relates to a component device, in particular for a primary supporting component of an aircraft, which comprises a first component element, a second component element, a bonding providing a connection between the first component element and the second component element, a marker substance device configured to dispense a volatile marker gas to the environment when in contact with the surrounding air and being hermetically sealed from the surrounding air by the first component element, the second component element, and/or the bonding if the bonding is not damaged, and a detector device configured to detect the marker gas dispensed by the marker substance device.

A micro flow channel chip having high shape accuracy is provided. A micro flow channel chip includes a base material 12 having a groove 121 formed on one surface; and a resin film 14 joined to the surface of the base material 12 so as to cover the groove 121 of the base material 12, in which the resin film 14 contains a (meth)acrylic resin (A), and the (meth)acrylic resin (A) contains a structural unit (A1) represented by Formula (1).

##STR00001## (In Formula (1), R.sub.1 and R.sub.2 each independently represent a hydrogen atom, a methyl group, an ethyl group, or a propyl group; and R.sub.3 represents an alkyl group having 3 to 6 carbon atoms)

A grooved resin molded part which when joined to another molded part, can form a composite molded product having an enhanced strength. This part contains an inorganic filler and has multiple grooves formed by partially removing the resin, such that the filler is exposed in these grooves. The depth of the grooves may be at least one-half of the length of the grooves in the shorter direction. The filler may have a fibrous shape; and the longer direction of the filler may be different from that of the grooves. The part is obtained by subjecting a resin molded part containing the filler to laser irradiation or the like to form multiple grooves in which the filler is exposed.

A microfluidic structure comprising a thermoplastic portion defining a microfluidic recess, a bonding layer on the thermoplastic portion and a siloxane elastomer portion covalently bonded to the bonding layer to seal the microfluidic recess. The microfluidic recess can therefore be formed simply, quickly and cheaply using known injection molding techniques, which are not hampered by the need for a curing step. However, the positive qualities associated with elastomers can be brought to the structure by using this to seal the microchannels. The bonding layer can be formed by silica deposited on the thermoplastic portion using techniques known in the field of optics.

Disclosed are thermoset/thermoplastic composites that include a thermoset component directly or indirectly bonded to a thermoplastic component via a crosslinked binding layer between the two. The crosslinked binding layer is bonded to the thermoplastic component via epoxy linkages and is either directly or indirectly bonded to the thermoset component via epoxy linkages. The composite can be a laminate and can provide a route for addition of a thermoplastic implant to a thermoset structure.
