| چکیده | ||
| Hybrid polymer nanocomposites (HPNCs) represent a promising class of materials for various engineering applications. This study investigates the impact of combining nanoclay (NC) and carbon nanotubes (CNTs) on the thermal and mechanical properties of epoxy matrices. Mechanical and thermal properties of HPNCs were characterized by using thermogravimetric analysis test (TGA), dynamic mechanical thermal analysis test (DMTA), thermomechanical analysis tests (TMA), scanning electron microscopy (SEM), flexural, tensile, shear, hot plate, and modal tests. Mechanical parameters were compared with theoretical results from the Halpin-Tsai method. Results indicate that incorporating up to 5 wt % of NC together with epoxy/CNT nanocomposites enhances CNT dispersion, leading to improvements in degradation temperature (+1%), glass transition temperature (+10%), thermal stability (50% increase in residual ash), storage modulus in the plastic range (+39%), transverse bond density (+41%), thermal expansion coefficient (-17%), flexural strength (+17%), elastic modulus (+85%), shear modulus (+11%), and natural frequency of the beam (+42%). | ||
