US 9,446,574 B2 · Method for bonding plastics and method for releasing a bond in the plastic composite and a plastic composite

Abstract

The invention relates to the field of chemistry and concerns a method suitable for example for use in the automotive industry or in aircraft construction. The object of the present invention is to provide a method by which a bonding of the regions of the plastics that are in direct contact is accomplished. The object is achieved by a method for bonding plastics in which materials which contain at least one electrically conductive material and only partially cover the plastics are applied to at least one of the plastics to be bonded, then the plastics are brought into contact with one another, at least in the region with the materials, and after that at least this region is exposed at least once to an alternating electromagnetic field.

Dependent claims

Method for bonding two layers of plastics to one another, the method comprising:

applying materials to at least one of the two layers of plastics that are to be bonded, which materials only contain at least one electrically conductive material and which only partially cover the at least one of the plastics,
subsequently bringing the two layers of plastics into direct physical contact with one another at least in a region with the materials, and
exposing at least the region at least once to an alternating electromagnetic field to bond two layers of plastics to one another via a chemical bond.

Dependencies are inferred from the claim text.
