Global warming and resource depletion are the main two issues that whole world try to reduce to keep our planet. So the production of synthetic fillers consumes energy, substances beside the pollution in air, soil and water. This work dealt with the preparation of green composite. The adding effect of palm seeds powder as natural additives on the mechanical properties of polyester resin were determined. Three different weight fractions of powder was added (3 %, 6 %, and 9 %). The composite were prepared using (Hand Lay-Up) approach. The utilized palm seed powder was pre-prepared using shear milling of well-dried palm seeds and then characterized using AFM analyzer. Granularity cumulating distribution report showed that the average diameter for 123 grains was 92.87 nm. 2D and 3D topography was also investigated. Tensile test, flexural test, impact test and hardness test were performed to determine the mechanical characteristics of composites. Obtained results revealed that the flexural modulus, impact strength and hardness properties enhanced with the increment of powder weight fraction incorporated in polyester matrix. While the values of tensile strength, tensile modulus, elongation percentage and flexural strength properties deteriorated with the increasing of weight fraction of powder.
