Özet
In this study, the synthesis and characterization of synthetic polymeric adhesives and the mechanical properties of metal-metal joints bonded with these adhesives were investigated. Adhesive technology enables the use of adhesives that show high performance under static and dynamic loads and replaces classical joining methods. The bonding process is an easy and cheap process. It easily joins very thin or thick parts and since it contains lightweight connecting elements, its strength/weight ratio is extremely high. It is used to join various materials in many sectors, especially in the automotive sector. There is no alternative to the bonding method in automobile parts where friction is high (to fix the brake pad to the composite material). In this study, Pol(GMA) polymer and pol(GMA-co-PEGMEMA) copolymers were synthesized with the free radical polymerization (SRP) method at different feed rates. In order to increase the chemical, thermal and mechanical strength of polymeric adhesives, their composites were prepared with micro-scale metal oxides (Ulexite). It has been determined that the addition of 3% by weight nanoclay to epoxy adhesives increases the impact and tensile strength of epoxy by 88% and 21% (Zhang et al., 2018). The obtained polymeric and polymeric composite adhesives were used to bond metal-metal single-action lap joints and their mechanical properties were examined according to ASTM D1002 standards. Thus, both the interface interactions of the epoxy adhesive were tried to be strengthened (reduced brittleness) and its thermal and mechanical performance were increased.
