“…The motivation of this study is due to the increase of the use of composites in automotive and aerospace applications and to the necessity to replace or repair in case of need. In previous studies, 20 it was demonstrated that this adhesive give good results for PP substrates. In this work, it was shown that this adhesive gives good mechanical performances also for epoxy-based substrates.…”

“…The chemical, thermal and mechanical properties of the adhesive were studied in a previous work. 20 The impact properties of this modified adhesive are presented in Ciardiello et al 21 The modified adhesive was prepared by using a hot plate for melting the neat adhesive and by adding 5% weight of iron-based particles with different size. The sizes of the iron particles used in this work are 450 mm, 60 mm and 1-6 mm.…”

“…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.

Abstract. In this study, the adhesive property testing methods of hot-melt pressure-sensitive adhesive containing styrene thermoplastic elastomeric used in Non-woven material surface bond were studied. The coating thickness, sticking time before test, aging time, peeling rate, angle of initial adhesion test and material of permanent adhesion test were analyzed, which refers to the parameters in the process of test samples preparation. The experiment results showed that the HDPE test plate is better than the traditional steel test plate for the measurement of the HMPSA permanent adhesion.

In this work, the mechanical characterization of adhesive joints made with a thermoplastic adhesive, modified and not modified, has been presented together with the separation tests that are possible by the use of metal nanoparticles embedded within the adhesive. A polyolefin adhesive has been modified with two weight concentrations (5% and 10%) of iron oxide nanoparticles. These particles increase their temperature under electromagnetic field; in this way, they are able to melt the adhesive and, therefore, separate the adhesive joints. The mechanical properties of single lap joints (SLJs) prepared with the neat and modified adhesives have been performed by using different overlap lengths and thicknesses. SLJs prepared with the nanomodified adhesive present higher loads compared with the neat one. Separation tests have been carried out on SLJ specimens to measure the times needed to disassemble the adhesive joints. Scanning electron microscope analysis has been carried out to study the distribution of the particles.
