Summary
The state of the art requires a closed waiting time of about one hour for the beech glulam production. This has a negative influence on the production costs. Micro structured surfaces showed good performance in combination with coatings. The authors have performed tension-shear and delaminating test in order to investigate the influence of micro structured surfaces on the bond quality of hardwoods. The results are very promising and show clearly improved delaminating resistance for all tested adhesive. No closed waiting time was needed to achieve satisfying results using MUF in combination with beech.
