Abstract
A connection method, in addition to a functional part used in it and to a flame-retardant total system, connects a single- or multilayer functional part (10) to a third component (20). The functional part (10) has functional elements (14, 16) projecting on one side. The functional part (10) is formed at least partially from a material at least partially transparent to laser light. A blocking layer (18) is disposed to be at least partially opaque to laser light such that after passage of the laser light through the functional part (10), the laser light inside the blocking layer (18) generates heat by absorption for melting the functional part (10) and/or the third component (20) to connect them to one another.
Claims18
A method of connecting a single or multiple layer functional part to a component, the method comprising the steps of:
- providing a functional part including a substrate element having closing or adhesion function elements in a form of hook-and-loop fasteners or Van der Waals fasteners protruding on a first side of said substrate element and formed as one layer of the functional part, the functional part being formed at least partially from a material at least partially transparent to laser light;
- disposing a barrier layer at least partially opaque to laser light such that after passage of the laser light through the functional part, the laser light inside the barrier layer generates heat by absorption of the laser light;
- placing the functional part and barrier layer on a component;
- and
- exposing the functional element to laser light to melt from the heat generated in the barrier layer by the laser light the functional part or the component to connect the function part and the component.
A functional part for forming a connection with a component, the functional part comprising:
- a substrate element having closing or adhesion function elements in a form of hook-and-loop fasteners or Van der Waals fasteners protruding on a first side of the substrate element and formed as one first layer with the substrate element, the first layer being formed as least partially from a material at least partially transparent to laser light;
- and
- a barrier layer on a second side of said substrate element opposite the first side thereof, the barrier layer being at least partial opaque to laser light.
A flame retardant total system, comprising:
- a substrate element having closing or adhesion function elements in a form of hook-and-loop fasteners or Van der Waals fasteners protruding on a first side of the substrate element and formed as one first layer with the substrate element, the first layer being formed as least partially from a material at least partially transparent to laser light;
- a barrier layer on a second side of said substrate element opposite the first side thereof, the barrier layer being at least partial opaque to laser light;
- a second layer is provided on the second side of the substrate element and having an excess portions thereof extending laterally at opposite ends at least partially beyond the substrate element and being formed at least partially of a laser permeable material;
- and
- an adhesive compound on a side of the second layer remote from the substrate element.
