ABSTRACT:
The invention is directed to a lightweight barrier and armor materials and, ore particularly, to a method of using a syntactic foam for protecting a desired portion of a fixed structure (e.g., building) or movable structure (e.g., armored vehicle or ship) from ballistic impact. The method of the present invention includes the following steps: (1) providing a mold defining therein a predetermined shape or an enclosed space in a fixed or movable structure; (2) providing a mixture of between about 40 percent and about 80 percent by volume of microspheres and between about 60 percent and about 20 percent by volume of an uncured binder material; (3) pouring the mixture into the mold; (4) curing the mixture to form a syntactic foam barrier material in the form of the predetermined shape; and (5) placing the barrier material in a relationship with the structure to be protected wherein the desired portion of the structure is protected from ballistic impact. The resulting protective barrier material is adapted to absorb and contain bullets and other ballistic penetrators and to maintain structural integrity upon impact thereof. The present method may further include the steps of providing external reinforcement and/or internal ballistic impact absorbing components to the barrier material.
