Flame and Blast Resistant Materials for Force Protection

Abstract:

This report is concerned with the development of a fire retarded blast resistant polyurea. Any blast resistant material must offer protection not only against a blast but also against the possibility of an accidental fire. In this project more than fifty different materials were investigated but alone and in a variety of combinations to determine the best system to offer fire protection to polyurea. The various formulations were initially evaluated using the cone calorimeter and the two key ingredients were found to be expandable graphite and ammonium polyphosphate. The combination of these two additives reduces the peak heat release rate from more than 2000 kWm2 to about 100 kWm2. This indicates that there is a significantly smaller fire. When the system is evaluated by the ASTM E-84 Flame Spread protocol, a solid Class B performance is obtained. Since pristine polyurea is not classified according to this testing protocol, this represents a great improvement in fire retardancy.
