Effect of reinforced system by palm fibers on the mechanical and insulation (thermal and acoustic)‎ properties for polymer composite materials

الملخص EN

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.
