Abstract (EN): Extensive research has explored the enhancement of mechanical properties in adhesive joints through additives, particularly nanomaterials like carbon nanotubes (CNTs), which exhibit notable potential based on existing studies. However, achieving uniform dispersion of CNTs within adhesives remains challenging. While ultrasonication is a common method, adjusting parameters for optimal dispersion is often overlooked. This study addresses this gap by using viscosity measurement to optimize ultrasonication time and nanoparticle dispersion. Additionally, we evaluate how both overlap length and nanoparticle weight percentage impact shear strength of single lap joints. Viscosity analysis show that increased CNT weight prolongs the optimum sonication time, but not linearly. Furthermore, optimal sonication time differs between resin and hardener with the same CNT weight ratio. Tensile tests reveal that 0.1 wt% CNTs provide the highest shear strength. Additionally, it was found that increasing overlap length reduced the average shear strength in joints containing CNTs.
