Adhesive Testing

 

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
