C. Experimental Procedure
The experiments were designed to evaluate different properties such as tensile strength, hardness, and thermal conductivity. The procedures followed are detailed below:
Tensile Strength Test
Tensile tests were performed using the Universal Testing Machine. The samples were prepared to standard dimensions and the force was applied until the specimen fractured.
Hardness Test
The Vickers Hardness Test was conducted to measure the hardness of the metals and polymers. A diamond indenter was pressed into the surface of the material and the size of the indentation was measured.
Thermal Conductivity Test
Thermal conductivity was measured using a specialized apparatus. The materials were subjected to a heat flux and the temperature difference across the sample was recorded.
