Abstract Scope |
Elium thermoplastics excel in structural applications due to their efficient processing, recyclability, and design flexibility. However, while Elium exhibits good mechanical performance in terms of strength, stiffness, and fatigue resistance, it cannot match high-performance thermosets and thermoplastics. Research explores avenues to enhance mechanical performance of Elium, including incorporating high-performance reinforcing fibers, modifying processing cycles, and utilizing compatibilizing agents, functional group additives, and resin blends.
This current study introduces adding nanoparticles to Elium. It was reinforced with three varying concentrations of ferromagnetic particles (Fe3O4) using a shear mixing process. The nanocomposites were tested in a single lap joint configuration to determine effects on Elium's mechanical properties. Baseline data was established by testing GFRP single lap joints bonded with unreinforced Elium under a constant quasi-static displacement rate of 5 mm/min. Identical joints were bonded using the nanoparticle reinforced adhesive and subjected to the same testing conditions. The mechanical response was characterized in terms of tensile strength and failure strain. An Added objective was to investigate the recycling capability of reinforced Elium under induction loading at all three concentrations. The tested nanoparticle reinforced Elium lap joints were recycled using both induction heating and conventional oven heating. The recycled lap joint samples were re-tested and a comparison between their tensile mechanical response was investigated.
