Wood and Surface Technology

The use of wood and wood products as building material strongly depends on their material, processing and use properties. The group "Wood Technology / Surface Technology" is involved in the analysis and the improvement of these properties in the fields of wood physics and mechanical technology as well as regarding weathering protection and adhesive bonding. A special focus is put on the wood surfaces, where the primary interaction with other materials and the environment takes place. The activities range from "forest oriented" wood research (forestry - wood chain, interface forest - wood processing) to the use characteristics of assembled wooden components and thus cover the wide area from raw-material to end-use applications. 
Competences / methods
  • Mechanical and moisture-related material tests (solid wood, wood-based materials, composites)
  • Microscopy of biological materials (light microscopy, SEM, TEM, UV-microscopy, partly with elemental analysis)
  • Surface characterization: visual assessments, microscopy, colour, gloss, topography, roughness, hardness, wetting behaviour (contact angle, surface energy)
  • Coatings: film structure and thickness, adhesion, natural and artificial weathering tests (EN 927)
  • Adhesive bonding: mechanical tests of bond line integrity (e.g. EN 205, EN 302-1, EN 392) / Delamination (e.g. EN 302-2, EN 391)
  • Special methods: dynamic mechanical analysis (DMA)
