3 Research interests Bonding is the basis for all wood composites as adhesion and cohesion contribute to their mechanical stability. The team Advanced Bonding investigates adhesives and wood adherent properties. New adhesives, also based on renewable raw materials as well as ideal bonding systems for novel wood composites, wood surface properties, adhesive distribution are investigated & developed. 3
4 Adhesion force Wood surface properties Advanced Atomic Force Microscopy techniques to characterize and understand physical and chemical surface properties on small length scales adhesion force Surface age [h] Frybort et al. (2014) Colloids and Surfaces A 4
5 Adherent - adhesive interaction Micromechanical and surface properties Micromechanical properties of adhesives, adherents and interfaces Cross section of a halved wood fiber embedded in PUR with nanoindents 5
6 Technological properties of adhesives Adhesive wood interactions wetting, cold tack, curing, additives Torque for MUF at 43 C HDF surface temperature influenced by different relative humidities of the surrounding air 6
