Polymer-based nanocomposites are extensively used composite materials in the industries such as automobile, aerospace, marine, biomedical, and others. This is due to their remarkable properties that can be achieved through the combination of polymer matrix and nanofiller to yield distinct and improved nanocomposite properties. Properties such as lightweight, easy to shape, high strength, and others are the most targeted in the mentioned industries, and polymer-based nanocomposite materials are the possible materials to yield such properties. This paper presents the experimental study on the effect of Calcium Carbonate (CCaO3 nanoparticles weight fractions on mechanical properties of P A6/CCaO3 nanocomposites at various temperatures. Polyamide-Nylon 6 (PA6) was reinforced with (CCaO3) nanoparticles at various weight fractions to produce PA6/CCaO3 nanocomposites. The PA6/CCaO3 nanocomposites tensile test samples were produced according to the injection molding at weight fractions of 0 wt%, 0.5 wt%, 1 wt%, and 1.5 wt% of CCaO3. The tensile tests were then conducted on the produced PA6/CCaO3 nanocomposites samples at the test temperatures of 25 ⁰C, 35 ⁰C, and 45 °C. The obtained results showed that an increase in CCaO3 increases the elastic modulus and the tensile strength of the PA6/CCa03 nanocomposites up to 1 wt%. The tensile test results also demonstrated that elastic modulus and tensile strength of PA6/CCaO3 nanocomposites decrease at 1.5 wt°% due to the agglomeration of CCaO3 through the PA6 matrix. Moreover, the results showed that an increase in test temperature decreases the elastic modulus and tensile strength of the PA6/CCaO3 nanocomposites.
