Abstract : Fibre reinforced materials with low densities have been examined in order to find substitutes for high strength aluminium which is used for some ammunition sabot elements being subjected to short duration high stresses. These materials were polymers and magnesium alloys reinforced with short-fibres. As fibre material glass as well as carbon and aluminium-oxide was taken. Quasi-static and dynamic compression tests were performed at strain rates from 10-4-s to 103-s with both materials. The mechanical properties of the fibre-reinforced magnesium alloys were also compared to their matrix materials. Experiments proved the applicability of the fibre-reinforced sabot elements at mass gains of about 30%.
