Abstract

In this study, polyester composites reinforced with pistachio shells powder (P.) with an average
diameter (150 – 200 μm) with different weight ratios (0.5%, 1%, 1.5%, 2%, and 2.5%) were
prepared to the resin. The Shore D hardness, thermal conductivity (K), and the glass transition
temperature (Tg) of the samples were examined. The results showed that the Shore D hardness
increases with the increase of the reinforcement ratio and its maximum value is (87.55) at (2.5%
P.) While the value of hardness at (0%) is (86.5). The thermal conductivity increases slightly with
the increase in the percentage of reinforcement and its maximum value is (0.213253 W/ m. K) at
(2.5% P.), while the value of K at (0% P.) is (0.170264W/ m. K), but with this slight increase in
thermal conductivity, polyester composites remain from the insulating materials. The minimum
(Tg) of (UPE/ P.) composites was the value (113.898°C) at (2.5% P.). Polyester composites are
used in wood paints, either in primitive finishes or final finishes.
