In this study, an experimental comparison has been made between the traditional plastic materials (Polypropylene and Polyethylene) and selected composite materials (Perlon-Carbon-Perlon and Hybrid Carbon fiber-Glass fiber) to manufacture a long life Partial Foot Prosthesis. To improve the mechanical properties, increase the lifetime of the prosthesis, and reduce the cost to the patient, two types of composite materials were used and compared with plastic materials. Samples were manufactured and tested with different test methods (Tensile, flexural, and fatigue test). All tests were performed at room temperature. The results showed that the composite materials achieve a large increment in mechanical properties such as (σy, σult, E, σb, and Ef) which were increased to a percentage of (200% - 261%), (330% - 243%), (295% - 203%), (276% - 270%), and (413% - 301%) in Perlon-Carbon-Perlon lamination as compared with Polypropylene and Polyethylene respectively. However the increasing percentage in Hybrid Carbon fiber- Glass fiber was (353% - 270%), (470% - 347%), (388% - 267%), (203% - 199%), and (244% - 178%) as compared with Polypropylene and Polyethylene. At the same time, the fatigue life was sharply increased in both of the Perlon- Carbon-Perlon and Hybrid Carbon fiber-Glass fiber.
