Samples of plastic agricultural residues composites were prepared for different compositions. Mechanical,thermal and physical tests were performed for all samples. Tensile, flexural, compression, hardness and Izod impact tests were performed as mechanical tests. Optical, thermal mechanical and density tests and measurements were also conducted for all samples to insure and confirm the physical properties and stabilities. Results of56 %weight percentage ratio of reinforcing phase (agricultural residue) shows a good properties for samples which include coupling agent, UV Stabilizer and lubricantsas 7% of weight percentages.
