Bonded multi-layer composite plates and a method for producing multi-layer composite plates

摘要

The invention relates to a multi-layer composite plates and to a method for producing multi-layer composite plates. Said multi-layer composite plates are comprised of two outer metallic slabs which serve as top and base plates and which are joined to a deformable connecting material located therebetween. The top and base plates are joined to the connecting material by means of a foaming adhesive which fills the cavities remaining in the composite. The cavities remaining in the composite are completely or partially filled by the adhesive. According to the method for producing multi-layer composite plates, adhesive is introduced between the layers to be joined, and the adhesive is subjected to a thermal treatment. The adhesive is completely or partially hardened during the thermal treatment. In the case of the partially hardened adhesive, the adhesive is completely hardened during an additional thermal treatment only after the multi-layer composite plate is reshaped.
