This is a study on evaluating the effect of nano-calcium carbonate (CaCO3) particles on the mechanical properties of thermoplastic casts, which were performed by mechanical tests, such as scanning electron microscopy and energy dispersive spectroscopy. Composites loaded with a mass rate of 1-2wt% of nano-CaCO3 particles in polyethersulphone (PES) showed the most excellent mechanical function. The increase in the rate of compressive strength, the maximum compressive modulus and the flexural modulus increases is 47%, 51% and 32% in contrast to neat thermoplastic resin, respectively. The improvement in mechanical properties is attributed to the nanocomposites based on the modified nano-CaCO3 fillers that perform higher modulus and lower Poisson's ratio than neat PES resin.
