Adhesive bonding technology gained popularity especially in the field of light weight design due to multi-material construction. It replaces traditional joining methods, e.g. welding, riveting, etc. and is found in automotive, aerospace, civil engineering and other applications.
At CEST we are focusing on the following:
- Characterization of bonding performance and failure pattern
- Impact of substrate pre-treatments
- Impact of environmental conditions
Special focus on automotive application includes:
- Lab scale automotive electrophoretic coating process
- Broad coverage of environmental aging tests
– Salt spray test (EN ISO 9227)
– Cyclic corrosion tests (e.g. VDA 621-415)
– Cataplasma test (DIN EN ISO 9142)
Testing of adhesive bonds mainly performed are:
- Lap shear tests (according to DIN EN 1465)
- T-Peel tests (according to EN ISO 11339)
- Evaluation of failure pattern according to EN ISO 10365 and DVS 3302
- Others possible on request
