- Abstract:
- Adhesives with different physical and mechanical properties are used in wood-adhesive bonds. Up to now little work has been done to analyze the effect of mechanical properties on the stress transfer in a bond. In the present work an effort was made to characterize specific zones existing in a wood-adhesive bond. More precisely, adhesives were characterized mechanically, and their ability to penetrate wood cell walls was analyzed. Furthermore, the mechanical effect of cell wall penetration in interphase cell walls was studied. Finally, a macroscopic test set-up, i.e. the scarf joint geometry, which allows to measure differences in adhesive performance, is presented. Besides conventional mechanical testing, sophisticated techniques like Electronic Laser Speckle Pattern Interferometry, Nanoindentation and Scanning Thermal Microscopy have been applied in this work on wood and wood adhesives to determine different properties on the cell wall level.
