The effect of alumina and tough nylon 66 on microparticles’ presence the mechanical and thermal properties of epoxy adhesives is assessed here. In order to distribute the adhesive formulation components, in a uniform manner a mechanical stirrer is applied. The effect a combined percentage of nylon66 at (20،30،40 pph) and alumina micro-particles 20 μ (50,60,70 pph) selected based on Taguchi expe...
