Effects of Silica/Clay Nanoparticles on Microstructural and Mechanical Properties of Epoxy Based Adhesives

Improving the mechanical properties of epoxy-based adhesives with nanoparticles is one methods which justifies use adhesive joints significantly. This work studies strength adhesively bonded single-lap (SLJs) considering pure adhesive, reinforced nano-silica particles (NSPs), nano-clay (NCPs), and a combination both nano particles. Uniaxial tensile testing SLJs was conducted to reveal failure loads their elongations at failure. Furthermore, Scanning electron microscope (SEM) images X-ray Diffraction (XRD) Analyses were used investigate dispersion quality. It observed that just 1 wt.% NCPs or 2 NSPs improve load significantly whereas generally leads large agglomerations. also concluded quality key by shifting mechanism from adhesion cohesion type.
