Slow Heating and Cushioning Evaluation of Foam Dunnage Materials for Ammunition Packaging
Abstract
A high temperature drop-in replacement for polyethylene (PE) foam packaging dunnage is desirable to some ammunition items. Various foam materials were tested at small-scale for heat resistance up to 400 deg F. Those materials capable of withstanding exposure to high temperature were subjected to three small-scale cushioning tests that only a cross-linked polyamide foam was able to successfully pass. Heating tests proved that the polyamide material is extremely resilient to high temperature exposure. Due to the cross-linked nature of the material, it deforms plastically after compression; however, the overall result was acceptable. Another series of heating tests was conducted using inert ammunition with high fidelity 40-mm M430A1 packaging in a slow cook-off environment. These tests successfully proved that the polyamide dunnage continues to provide cushioning support at the system level. This material may be a suitable alternative to PE foam dunnage currently used for packaging ammunition. Additional work needs to be done to prove that the material has acceptable cushioning properties at all densities, specifically dynamic cushioning.
