Researchesspecialized in manufacturing of prostheses showed a major development in improving the mechanical and physical properties in the trend to get the best mechanical specifications, lighter in weight, lower cost and ease of manufacturing. For this purpose this research includes manufacture of above the knee prosthetic socket of lamination of four layers consisting of (1 bamboo 2 fiber carbon 1 bamboo) instead of lamination of ten layers which consist of (4 perlon 2 fiber carbon 4 perlon) which is most commonly used in the manufacture of prosthetic socket at the moment. Tensile test and fatigue test were conducted, as well as interference testing pressure between the residual limb of leg of the patient with socket by device F-Socket to use these pressures later as boundary condition in the simulation program ANSYS 14.5, which will simulate the distribution of Von-Mises stresses, values of deformation and the factor of safety for both available and proposed sockets. The results revealed an increase in the values of each of the yield stress and tensile stress Young's modulusand stress endurance by 20.1%, 162.7% 0.80% 0.241%, respectively, as the results of the prosthetic socket simulations manifested increase in safety factor from 0.998 to 3.85 and decrease in the highest amount of deformation from 10 mm to 5.5 mm.
