  • Polyurea composite armor
    Patent number: 8580387
    Abstract: A composite armor including a ballistic armor layer and a directly attached polyurea layer. The polyurea layer is the cured reaction product of an isocyanate curing agent and a mixture of diamines having the general formula: H2N-Ph-(C?O)—O—(CH2—CH2—CH2—CH2—O)n—(C?O)-Ph-NH2, wherein in the mixture n in the ranges from 3 to 14 and the weight average value of n is about 9 to 10. Ph represents phenyl. In a preferred embodiment, the polyurea layer is the strike face. The composite armor is useful for light armor applications in which weight is a factor such as military vehicle armor and military boat armor.
