Benefits of technology

[0005] Therefore, it is an object of the invention to provide a hard armor composite which incorporates a fabric backing including high performance, low denier-per-filament (dpf) fibers.
[0006] It is another object of the invention to provide a hard armor composite which offers substantial ballistic performance and is relatively lightweight.
[0007] It is another object of the invention to provide a hard armor composite which enables use of a less costly and heavier ceramic material without sacrificing ballistic performance.

Problems solved by technology

An inherent problem in the prior art is that ceramic armor is configured for a fixed level of protection against a single ballistic threat.
However, due to limited production and sources of Spectra Shield® PCR and Spectra Shield® Plus PCR, a need exists for an alternative acceptable ballistic fabric construction which can be readily obtained from multiple sources.

Embodiment Construction

[0035] Referring now specifically to the drawings, a hard armor composite according to the present invention is illustrated in FIG. 1, and shown generally at reference numeral 10. In one application, the composite 10 is a small arms protection insert (SAPI) designed to protect against multiple small arms bullets and projectiles. The composite 10 is constructed according to United States military specifications, CO / PD 00-03D dated Jan. 13, 2003, in sizes X-small, small, medium, large, and X-large ranging in weight from 2.85 to 5.35 pounds. All SAPI sizes have a uniform nominal areal density of 5.1 pounds per square foot or less. The dimensional measurements are indicated in Drawing Nos. 2-6-265, 2-6-266, 2-6-267, 2-6-268, and 2-6-269 of CO / PD 00-03D. The entire subject matter of CO / PD 00-03D, including text, drawings, tables, and charts, is incorporated herein by reference.

[0036] As shown in FIGS. 1 and 2, the hard armor composite (SAPI) 10 comprises a ceramic plate 11 and ballistic...

Abstract

A hard armor composite includes a rigid facing and a ballistic fabric backing. The fabric backing is carried by the facing, and includes an array of bundled high-performance fibers. The fibers have a tensile strength greater than 7 grams per denier and a denier per filament ratio of less than 5.4.

Description

TECHNICAL FIELD AND BACKGROUND OF THE INVENTION [0001] This invention relates to a hard armor composite, and more particularly to an improved small arms protection insert (SAPI) applicable for protecting against multiple small arms bullets and projectiles. In a preferred embodiment, the invention incorporates a rigid ceramic plate and a ballistic fabric backing. [0002] Ceramic armor is typically used for body armor and for the outer coverings of different types of vehicles, such as various types of land vehicles, ships, and aircraft. Typically, ceramic tiles are adhesively secured to a substrate then encapsulated in an outer cover. The armor system is then attached to a vehicle by a variety of means or merely placed in a fabric pocket, as in the case of body armor. An inherent problem in the prior art is that ceramic armor is configured for a fixed level of protection against a single ballistic threat. [0003] The current SAPI incorporates ceramic and an extended chain polyethylene f...
