Abstract

A transparent armor composite system for defeating firearms projectiles, consisting of transparent glass, glass-ceramic, or ceramic materials in small, spherical segments, bound by a refractive index-matched polymer resin. This composite matrix is backed by a transparent polymer spall shield and may have a transparent facing, as well as air-gap layers incorporated into the structure. The composite (TRIIVIACS:
Transparent refractive Index-Matched Armor Composite System) offers the ballistic performance of glass/plastic laminate systems, with the non-ballistic damage resistance of plastic/plastic transparent armor laminates. Multi-hit capability is also improved over other transparent armor systems.

Claims What is claimed is:
1. A transparent composite structure for defeating firearms projectiles, said composite structure consisting of spherical segments of transparent glass, transparent glass-ceramic, or transparent ceramic material bound by a transparent, polymeric binder (hereafter referred to as the 'matrix% with a transparent backing.

2. A transparent composite structure according to claim 1, wherein spherical segments in the matrix are of the same size, or a heterogeneous mixture of sizes.
3. A transparent composite structure according to claim 1, wherein spherical segments are arrayed in a manner dictated by efficient tiling (i.e., with minimal 'dead space' between shapes).
4. A transparent composite structure (matrix) according to claim 1, wherein the transparent, polymeric, binder has the same refractive index as the spherical segments.
5. A transparent composite structure according to claim 1, wherein the transparent backing is of a rigid polymer, or polymer laminate.
6. A transparent composite structure according to claim 1, wherein the strike face may be faced with a transparent polymer or polymer laminate.
7. A transparent composite structure according to claim 1, wherein polymeric interlayers may be incorporated within the matrix.
8. A transparent composite structure according to claim 1, wherein an air-gap layer, or layers may be incorporated within the overall structure (i.e., within the matrix, within the

Description

TRIMACS (Transparent Refractive Index-Matched Armour Composite System) is a damage-resistant, multi hit-capable composite armour concept. TRIMACS
incorporates small spheres of a hard, transparent material (glass, or ceramic) in a polymer matrix with the same refractive index. TRIMACS can be adapted to use new, high-hardness ceramic technologies (sapphire, aluminum oxynitride, spinel, etc.) more economically than with monolithic transparent ballistic armour. Multi-hit capability comes from the discontinuous nature of the composite (isolating ballistic impact damage); the flexible nature of the polymer binder resists non-ballistic damage, such as being struck by rocks.
The composite can be formed into flat, curved, or hemispherical shapes.
Applications would include faceshields, armoured vehicle vision blocks and other transparent vehicle armour.
TRIMACS would be fabricated commercially using a vacuum-infiltration process.
An anti-spall backing (polycarbonate, or polyurethane) would comprise the inner surface.
The actual TRIMACS matrix would consist of a refractive index-matched inorganic/polymer combination (e.g., soda-lime glass and PMMA, borosilicate glass and PVB). An anti-scratch coating may be applied to the facing, atop an additional layer of polycarbonate, or polyurethane. Depending on the threat anticipated, the TRIMACS layer and backing could be increased in thickness. More exotic hard materials (aluminum oxynitride, etc.) could be used, where the threat warrants. Since producing high-hardness transparent ceramics in large, monolithic segments is extremely costly, TRIMACS could make their use economical, even for very large transparent armour components such as vehicle windshields.
The initial application for TRIMACS would be ballistic faceshields, for military and tactical police use. The resistance of TRIMACS to non-ballistic impacts (dropping, bumping against hard surfaces, etc.)¨along with ballistic performance superior to acrylic-polycarbonate laminates¨would make this an ideal market. Other protective eyewear, such as industrial safety goggles, could be candidates for TRIMACS
technology.
