Impact resistive composite materials and methods for making same

A composite for resisting impact from an oncoming projectile having a front strike face and a back wear face comprising:

• an elastomer selected from the group consisting of at least one selected from the group consisting of a polyurethane, a polyurea, and combinations thereof;
• an impact resistive substrate selected from the group consisting of a ceramic, a metal, an aramid ballistic fabric, a polymer, and combinations thereof, wherein at least a portion of the impact resistive substrate is coated by the elastomer to provide the composite having a front strike face coating and a back wear face coating and wherein a weight ratio of front strike face coating to back wear face coating ranges from 1:1.2 to 1:100;
• and
• optionally an adhesion promotion layer disposed between at least one surface of the elastomer and at least one surface of the impact resistive substrate.
