Abstract

Bonding is one of the key aspects of recent vehicle design, especially when multi-material structures are considered to contribute to the lightweight trend. Some innovative technologies, based on magneto sensitive nanoparticles dispersed in hot melt adhesive (HMA), have been already studied in order to reduce the cycle time of a vehicle and to allow for the recycling at the vehicle end of life. In this research activity, the effect of a 180 days normal ageing and three different accelerated ageing cycles (currently used by vehicle industries) of a thermoplastic adhesive with Iron (II,III) oxide nanoparticles embedded in the adhesive matrix have been studied. Performed Single Lap Joint (SLJ) tests prove the variations of the mechanical properties and adhesion strength during both the normal and accelerated ageings. Thermogravimetric analysis (TGA) and Fourier Transform Infrared Spectroscopy (FTIR) have been used to reveal the different degradation levels among the various ageing cycles. Results have been conveniently compared and criticized in order to show the differences and the similarities between the normal ageing cycle and accelerated ones.
