Natural fibers have become essential elements to produce composites, which\nhave the renewability, sustainability, low cost and less health hazardous. Natural\nwastes improved the physical and mechanical properties of polyester-\nbased composites. Reinforced polyester composites with natural fibers are\nspread widely in recent decades as an alternative to synthetics. This paper\ndeals with effectiveness of palm fronds when they were added to a polyester.\nPercentage of palm fibers with respect to polyester is considered through present\nwork. A Pin-on-disc tribometer has been used in experimental work under external\nforces, and the correlations of coefficient of friction have been used to\nmake analysis of the experimental results. Ibertest universal testing machine was\nused to measure the tensile strength at a crosshead speed of 8 mm/min. The experimental\nanalysis shows the improvement of properties of the used reinforced\npolyester, where, the results show that the highest values of coefficient of friction\nare 1.16667 for 5 N load and the lowest value is 0.55 for 9 N load. And the\nchange for load 11 N is not significant. And also, 7.01 MPa is the highest value\nfor tensile strength with the lowest value of modulus of rigidity 5.84 when the\npalm frond content is 3% and the lowest value of tensile test is 4.81 MPa with\nthe highest value of modulus of rigidity 11.9 when 21% content.
