Abstract: The mass of a sabot is its ultimate measure of its performance. The sabot is parasitic; therefore, great effort is made to minimize its mass. This report parametrically investigates the influence of material properties on the sabot design to identify paths of improvement. The mass of the rear sabot ramp is used to evaluate potential sabot material substitutes. The study indicates that low-density materials are significantly more efficient sabot materials than high stiffness materials for a given specific stiffness. Additionally, the significance of the sabot material's strength is evaluated, and its effect on the sabot's mass is quantified. It is found that the sabot material's strength has a decreasing significance as the material's specific stiffness increases.
