With a view to the large-scale suitability of hybrid materials with integral connections in primary components, the question of how to deal with the different linear expansions of the materials used when heat is introduced is still unresolved. To research this open question, inpro will start on April 1st, 2020 together with the partners Otto Fuchs KG, INVENT GmbH, DDP Specialty Products Germany GmbH & Co. KG and TÜV Süd Product Service GmbH as well as the Fraunhofer Institute for Structural Stability and System Reliability (LBF ) the BMBF-funded joint research project “Design and optimization of hybrid connections with special consideration of the different thermal expansions of the material partners – GOHybrid” (funding code: 03XP0275C, duration 2.5 years).

The overall goal of the joint research project is to reduce stresses in the integral hybrid connection made of metal and fiber composite plastic (FRP) by means of design, material selection and construction in such a way that a relevant lightweight construction potential can be tapped. As a result of this project, a significant increase in the marketability and the industrial application of hybrid materials in primary components is expected. In this context, the corrosive effects of other environmental influences on the material composite should also be considered. By using functionalized adhesives and the correct design of the connection, corrosion at the connection level should also be avoided.

As part of the joint research project “GOHybrid”, inpro is working on the sub-project “Modeling and virtual validation of cohesive hybrid connections”.
