المستخلص: | Phoenix dactylifera l. pinnae (the green leaves of dates palm) were used as natural reinforcing (strengthening) fibers to improve the mechanical properties of polyester as a matrix material, the fibers of the green leaves of dates palm were used in two lengths, 10 and 20mm with five rates of 0, 2.5, 5, 10, and 20%, where the reinforcing with the leaves fibers increases the hardness strength from 76.5MPa to be about 86.55MPa, the Impact value raised from about 0.313 KJ/m² to 0.461 KJ/m², in addition to that the flexural strength from 2.66MPa to be about 55MPa, and the thermal conductivity increases from 2.54 w/m. ℃ to 5.41 w/m. ℃ The results of the present search explains that the composite samples reinforced at rate 20% and 10mm fiber length gives the best results. |
