“…Following a procedure commonly adopted in the literature for HMAs, 7,10,17,18,20 pellets are melted together at 190 C, using a hot plate. At 190 C, the viscosity of the adhesive is low enough to easily mix the particles into the adhesive by mean of a glass rod for 10 min.…”

A hot melt adhesive -mainly used for bonding plastic component in automotive field -was modified with different ironbased particles to give it a reversible behaviour. Mechanical and physical properties of these reversible adhesives were experimentally assessed in the work. The modified adhesives, coupled with electromagnetic induction, are able to guarantee separation of the joints without any damage to the substrates for recycling, reuse or repairing of components. Single lap joint specimens were prepared using epoxy/glass fibres substrates and tests were carried out on neat and modified adhesive with 5% weight of iron and iron oxide. Three different Fe particles size were tested: 450 mm, 60 mm and 1-6 mm. The particles size of iron oxide was 50 nm. Separation was studied using single lap joint specimens under electro-magnetic induction. Experimental results showed that the maximum peak load decreases when the average particles sizes increase. The peak loads of the smallest particles were equal to the ones of the pristine adhesive. The elongation of the adhesives increases when the adhesive is modified with both iron and iron oxide particles. Finally, experimental tests on single lap joints coupled with electro-magnetic induction showed that separation of the substrates is possible using iron oxide particles. Electro-magnetic tests conducted on particles alone, helped to understand that bigger particles are able to overcome the melting temperature of the adhesive but hot-melt adhesives modified with these particles are not able to reach the melting. These tests showed that the number of particles into the adhesive matrix is very important for this kind of tests.

“…Unfortunately, these systems can introduce some damages in the bonded parts. Many methods and processes have been proposed that allow the dismantling of the adhesives without any damage, [9][10][11][12][13][14][15][16] but there is not an accepted method yet.…”

“…On the other hand, the need to find a better solution to cope up with the existing bottlenecks of composite manufacturing and assembling is well recognized. Hence, several companies and researchers have proposed integrating approach that allows structural optimization through parts consolidation and ''efficient'' manufacturing and joining methods [9][10][11].…”

“…[13] Recently, adhesive joints have been widely used in mechanical structures because of the enhanced performance of the adhesive. [31] Among the commonly used adhesive bonded joint configurations, scarf and stepped joints have been found to exhibit the highest structural efficiency because significant joint load path eccentricities (which ultimately act as stress raisers) are eliminated when compared with simple single or double lap joints. A scarf joint is the structurally most efficient adhesive joining method when compared with other adhesive joint configurations because the stress concentrations at the ends of the overlap area are minimized.…”
