Abstract

The DC60 bulletproof composite armor described in this invention consists of a force disperser and a force absorber bonded together with a special adhesive and encased in a surrounding layer for camouflage and shrapnel containment purposes. The force disperser is made of ceramics wired, meshd, or woven metal and attached to a metal backing plate using a shrink-fit technique. The stresses in the material created during this process significantly improve the armor's performance and help contain shrapnel, preventing it from scattering and harming others or the surrounding environment. The force disperser can be used as an insert or combined with the shock-absorbing layer. The adhesive used is a high-strength, special adhesive. By selecting appropriate materials and improving the armor's properties to be lightweight, capable of withstanding various levels and multiple rounds of ammunition, and by reducing manufacturing costs, this bulletproof armor is beneficial for protection against bullets and other ballistic weapons. The bulletproof composite armor described in this invention consists of a force disperser and a force absorber bonded together with a special adhesive and encased in a surrounding layer. For camouflage and shrapnel absorption purposes, force-diffusing plates are made of ceramics bonded to a metal backing plate using a metal wire, mesh, or woven metal structure. The plates are then wrapped using a shrink-fit technique. The stress generated during this process significantly improves the plate's performance and helps to contain shrapnel, preventing it from scattering and harming others or the surrounding environment. These force-diffusing plates can be used as individual pieces or integrated with shock-absorbing plates. A high-strength adhesive is used for bonding. By selecting appropriate materials and improving the properties of the bulletproof armor to make it lightweight, capable of withstanding various bullet calibers and rounds, and by reducing production costs, such plates are beneficial for protection against bullets and other ballistic weapons.

Claims (8)

Revised 10/07/58 1. Composite bulletproof armor consisting of a force-distributing plate made of specially arranged ceramic material combined with metal, heat-treated to create compressive stress across the entire plate, and a force-absorbing plate made of polymer composite, bonded to the force-distributing plate with a high-strength adhesive used for bonding polymer to metal, and encased in a polymer fiber layer. A unique feature is that the force-distributing plate has a thin metal cladding on the sides to help absorb impact force dispersed from the bullet to the next ceramic plate. This metal cladding extends to the surface of the ceramic plate to facilitate bonding during both heating and bullet impact absorption. The force-distributing plate is then encased in a shrink-fitting metal covering, made by cutting and/or folding sheet metal of the required thickness and wrapping it around the ceramic plate. Metal wire, mesh, or woven metal is then used to secure the ceramic plate to the covering. 2. Composite bulletproof armor as per claim 1, where the force-distributing plate is made of high-hardness ceramic material. and lightweight. 3. Bulletproof composite armor under claim 1 in which the force distribution plate is ceramic-encased with at least one type of thin metal side covering of a choice of thin foil or metal tape. 1. The composite bulletproof armor consists of a force-distributing plate made of specially arranged ceramic material combined with metal, heat-treated to create compressive stress across the entire plate, and a force-absorbing plate made of polymer composite. These are bonded to the force-distributing plate with a high-strength adhesive used for bonding polymer to metal and further encased in a polymer fiber layer. A unique feature is the thin metal sheath on the sides of the force-distributing plate, which helps absorb shock waves radiating from the bullet to the next ceramic plate. This metal sheath extends to the surface of the ceramic plate, facilitating both heating and impact absorption. The force-distributing plate is then wrapped with a shrinkable metal sheet of the required thickness, cut and/or folded, and secured to the ceramic plate using metal wire, mesh, or woven metal. 2. Bulletproof composite armor under claim 1, in which the force distribution plate is made of high-strength, lightweight ceramic material. 3. Bulletproof composite armor under claim 1, in which the force distribution plate is encased in ceramics with at least one thin metal side covering that is covered by a thin foil or metal tape. 4. Bulletproof composite armor as per claim 1, where metal tape has a thickness of 0.01-2.00 millimeters. 5. Bulletproof composite armor under claim 1, in which a force-distributing plate is encased in ceramics with a thin metal layer on the sides, welded in linear fashion, then pulled apart to form a honeycomb structure, and ceramic plates are inserted into the honeycomb cavities. 6. Bulletproof composite armor under Reservion 1, in which at least one of the following metals of choice shall be used: aluminum, aluminum alloy, titanium alloy, nickel alloy, stainless steel, or amorphous metal. 7. Bulletproof composite armor under Reservion 1 where at least one type of strong adhesive is selected to bond the polymer material to the metal, from epoxy adhesives requiring a catalyst or adhesives that are cured by ultraviolet light. 8. Bulletproof composite armor under claim 1 that can be used as inserted sheets for deployment, or painted/coated for camouflage purposes, or adapted to existing applications or structures, such as use in automobiles.
