The use of lightweight materials in the automotive and aviation industries is essential for boosting performance. Weight loss results in a decrease in fuel usage, carbon dioxide emissions, and other harmful pollutants. For the metal components utilized in the aerospace and automotive industries, polymeric composites offer a superior alternative material. In this work, the dynamic mechanical characteristics of hybrid nanocomposites made of polyamide 6 (PA6) are examined. TGA, DSC and melt flow index (MFI) were also examined. The matrix was made of polyamide 6. As reinforcements, copper nanoparticles (Nano Cu) multiwalled carbon nanotubes (MWCNT) were used. Testing was done on virgin Polyamide 6, virgin Polyamide 6 with 0.25 wt% MWCNT, virgin Polyamide 6 containing 0.2, 0.4, and 0.6 wt% copper nanoparticles and 0.25 wt% MWCNT. Injection moulding was used to create the specimens after the materials were combined in an extruder with dual screw. The specimens were made in accordance with ASTM standard D5279. The dynamic mechanical analyzer from universal TA Instrument was used for the experiments. Dynamic mechanical parameters including tan δ, loss modulus, and storage modulus were measured at temperatures ranging between room temperature to 393 K. It was investigated and discussed how the weight of the fillers MWCNT and Nano Cu particles influenced the dynamic mechanical properties. DMA results showed that the polyamide 6 loaded with 0.25 wt% of MWCNT and 0.6 wt% of copper nanoparticles has improved the viscoelastic characteristics.
