    The present experimental work was carried out with the purpose of defining the mechanical properties of a composite material formed by polyester resin and reinforced with laurel particles. For which two types of configurations and three types of volumetric variations were used, in order to establish the ideal combination that has the best mechanical properties of the composite material. In this investigation, tensile, flexural and impact tests were carried out under the norms ASTM-D3039, ASTM-D7264 and ASTM-5628, which established the ideal dimensions for the preparation of the specimens. Where later the results obtained from each of the configurations and volumetric variations obtained from the composite material were rehearsed and tabulated statistically. The type of stratification was by compression using a welded steel matrix ASTM-A36, which guaranteed us a smooth surface and an excellent surface finish of the material. Through the study carried out it was possible to determine that the best mechanical properties of the composite material fall on the type A configuration, with a particle size of 500 microns and with a volumetric fraction of 30 percent of laurel particle reinforcement plus 70 percent of polymer matrix of polyester resin. Showing results in maximum tensile stress of 27.39 Mpa, tensile elastic modulus of 2214.71 Mpa, maximum deformation 1.32 percent, maximum flexural stress of 117.09 Mpa, flexural elasticity modulus of 6924.7 Mpa, maximum deflection 3.46 mm and impact resistance of 0.19 J.
