چکیده

Due to their suitable thermal, electrical, and chemical properties, epoxy composites are constantly employed in the multi-structure, construction, electronics, adhesive, and coating industries. the distribution and dispersion of nanoparticles in the polymer matrix are essential and influential factors in epoxy nanocomposites’ mechanical properties. utilizing baking kinetic equations to evaluate and optimize the manufacturing process. the widespread adoption of destruction kinetics modeling by engineers has decreased product costs and improved product quality. the curing reaction mechanism is unaffected by adding nanodiamonds modified with carboxyl groups to pure epoxy resin. nanodiamond surface modification increases the curing reaction speed of epoxy nanomultistructure. the results of this study demonstrated that the presence of modified nanodiamond could increase the thermal stability of an epoxy nanocomposite hybrid sample. according to the findings, the activation energy of nano-multi structures modified with 0.2, 0.4, and 0.6% nanodiamond by weight decreased by 11.58, 18.95, and 22.96%, respectively. in nano-multi structures modified with 0.2%, 0.4%, and 0.6% nanodiamond by weight, the wear rate decreased by 83.14, 93.10, and 94.14%, respectively; the friction coefficient decreased by 46.03, 52.08, and 54.34%, respectively. the current study examined the influence of nanodiamond addition on morphology, mechanical and rheological properties, and modeling of baking kinetics, degradation kinetics, and tribological properties.
