Surlyn® 8940 ionomer is a copolymer of ethylene and methacrylic acid with thermally activated self-healing capacity. After ballistic impact was performed, mechanical, optical and thermal properties of the copolymer before and after the damage caused by the passage of bullet were examined. The ballistic test was successful and the material was immediately healed, but the damage is evident and its mechanical properties have changed. Stress-strain curves measured by means of tensile testing showed that the material has the yield point and large ductility. After the ballistic impact, characteristics are less uniform, the yield point vanishes, tensile strength and ductility are reduced and modulus only slightly decreases.
