In this research, the variable shot peening time and solidification time on the mechanical properties of natural composite materials (cotton, jute and polyester) was investigated. The experimental work included manufacturing samples of natural composite materials (cotton, jute and polyester) and applied different shot peening time (0, 5, 10, 15, 20, and 25) minutes with different time of solidification (2 and 6) days and the tensile test start to found the mechanical properties (module of elasticity, ultimate stress and poisson’s ratio). The results show that the increasing of the shot peening time till 15 minutes and solidification time till 6 days affect on the mechanical properties, where the maximum value of the mechanical properties (module of elasticity, ultimate stress and poisson’s ratio) is at 15 minutes of shot peening and 6 days of solidification time, and then these mechanical properties start to decrease after 15 minutes of shot peening, because of the sample weakness and fragmentation.
