AbstractBiodegradable poly lactic acid (PLA) samples were optimized and fabricated for flexural, tensile, hardness, and dielectric testing, according to the American Society for Testing Materials (ASTM). In order to achieve the highest value of tensile strength, flexural strength, and hardness, hot pressing compression molding was utilized to optimize PLA. Furthermore, not enough research was available regarding the preparation of PLA samples or composites using hot press compression molding. However, different processing variables such as temperature, pressure, compression time, holding and cooling time played huge roles. Each of these variables were investigated in order to optimize the PLA properties. Composites samples were also produced using the optimized processing parameters. These samples were then tested for tensile strength, which was 2.2 Mpa, flexural strength, 7.6 Mpa, Rockwell hardness C scale, 59, and dielectric constant/loss. The highest dielectric constant value achieved was 1.07810 at 1kHz frequency, and the highest amount of dielectric loss was 0.14910 at 2MHz frequency.
