This research was carried out to study the mechanical properties and thermal and acoustic insulation properties of prepared polymer composite. Petiole date palm fibers with the length (2-3mm) and with different volume fraction ratio (10, 20, 30 and 40%) were used as filler in preparation of polymer composite.
The research imply study effect of pre- deformation for petiole date palm fiber by chosen compression loads (0, 2, 4 and 6 MPa) on the mechanical properties as well as on the thermal and acoustic insulation properties of prepared composites. It was concluded that the pre-deformation to the fibers improves the thermal and acoustic insulation properties of prepared composite, as well as an increase in the tensile strength and hardness values with increasing compression load on the fibers. The highest values of the tensile strength and hardness reach to (133MPa) and (106) respectively for the polymer composite filled with 40% volume fraction of petiole date palm fibers which pre-deformed under compression load equal to 6 MPa.

The research aims to prepare composite materials of unsaturated polyester resin reinforced by palm fiber extracted from different locations (Trunk, Petiole (bases leaflet date palm tree), Rachis and Panicle) of the palm tree in Iraq. The study included the effect of fiber length and their location within the plant as well as the percentage of the volume fraction (0%, 10%, 20%, 30%, and 40%) on the mechanical properties, thermal and acoustic insulation for all the samples prepared.
The results showed that mechanical as well as the thermal and acoustic insulation properties increase with increased the volume fraction for all kinds of the date palm fibers, whereas decrease with increased fiber length also those properties depend on the natural of the date palm fibers as the following sequence (samples reinforced by petiole fibers > samples reinforced by trunk fibers > samples reinforced by rachis fibers > samples reinforced by panicle fibers).
