The ionomer Surlyn® 8940 is known for its ability to self-heal projectile impact damage. In previous studies, the resin was compression molded to obtain polymer sheets that exhibited the expected self-healing behavior. In this study, however, extruded polymer sheets were used. In contrast to the compression molded sheets, the extruded ones were not able to self-heal the impact damage. In order to clarify this change in self-healing behavior caused by the two different manufacturing processes, the compression molded and extruded materials were further investigated by tensile tests and differential scanning calorimetry (DSC). Furthermore, finite element simulations were done and compared with the experimental results.
