In this study, polyester composites reinforced with pistachio shells powder (P.) an averagediameter (150 – 200 μm) different weight ratios (0.5%, 1%, 1.5%, 2%, and 2.5%) wereprepared to the resin. The Shore D hardness, thermal conductivity (K), glass transitiontemperature (Tg) of samples were examined. results showed that hardnessincreases increase reinforcement ratio its maximum value is (87.5...
