“…The authors conclude that neither the adhesives capability to build up cohesive as well as adhesive strength is significantly deteriorated by application of the process. However, it is known that both cohesive [18] as well as adhesive strength [19] might be influenced / altered by both the presence of the CP as well as the inductive heating.…”

Adhesively bonded timber-based elements are often manufactured with two-component (2K) adhesives (mostly epoxies and polyurethanes), which usually need many days until full cure, i.e. mechanical performance, has developed. The study shows how wooden components can be bonded in significantly less time by using inductively heated Curie particles (CP), which are added to the polymers and heated by an electromagnetic field (EMF) up to the particle's Curie temperature, Tc, but not beyond. The investigations were carried out using small single lap shear (SLS) as well as medium-and large-sized Glued-in Rods (GiR), all of which produced with spruce adherends. Furthermore, two frequently used 2K adhesives were analysed (epoxy and polyurethane). It could be shown that curing times can be reduced from 1/10 days down to 10 min of inductive heating by application of the technique.
