  • Composite article providing blast mitigation and method for manufacturing same
    Patent number: 7687147
    Abstract: A composite article and method for manufacturing the same are disclosed. In one embodiment, a polyurethane-polyurea layer is disposed on a substrate. The polyurethane-polyurea layer includes a reaction product of an isocyanate component having from about 10% to about 90% of a toluene diisocyanate, by weight of the isocyanate component, and an isocyanate-reactive component having amine-terminated and/or hydroxyl-terminated compounds. The polyurethane-polyurea layer provides blast and fragment protection from explosive devices as well as ballistic mitigation.
