Project Description
The joining technology of adhesive bonding is very highly rated in today's industrial production. In contrast to thermal joining processes, the surfaces of the substrates remain undamaged and different materials can be joined together. An enormous advantage lies in the uniform distribution of stresses in the bonded joint. Thus, joining parts of structural joints can be designed thinner and components are produced significantly more weight-efficiently than with other joining technologies. The bonding process itself is highly complex and may quickly become uneconomical due to long pot life and fixing times.
The aim of the research project is to develop a joining technology based on the polymer ethylene vinyl acetate (EVA) that overcomes the disadvantages of bonding with liquid adhesives. The focus is on bonded joints of filigree and/or curved components with partly complex bonding surface geometries. Post-application chemical crosslinking ensures high structural load-bearing capacity of the bonded joints. Both processes can be decoupled in time and location. For these special requirements, different EVA compounds have to be produced, investigated and modified. After comprehensive laboratory tests, the performance of the developed joining technology will be demonstrated in component tests. The new bonding technology will allow easier and more economical production of lightweight construction elements and new types of energy generation systems on buildings.
