A critical technology challenge for structural material applications is to have a means for the reliable analysis of material damage and failure.
Thermoset polymers are good electrical insulators that are used in applications ranging from electronics to composite armor. They are rather poor thermal conductors, however.
Predictions of these signals were difficult to make due to the complexity of the physics unleashed by the detonation.
