Description

A NOVEL BULLET PROOF COMPOSITE TEXTURE AND THE PRODUCTION

METHOD THEREOF

Subject Matter of the Invention and Technical Field

The invention relates to a novel bullet proof composite texture and the production method thereof. The invention relates to a production method of composite fiber fabric or plate which is bullet proof against both small caliber pistols and large caliber rifles, which is comprised by combining materials such as UD (unidirectional) basalt, UD (unidirectional) fiber glass, polyethylene fiber DYNEEMA (trademark), aramid fiber KEVLAR (trademark), ceramic fiber and polyester vinyl ester resin at certain proportion and criteria, and layer number which can be increased or decreased according to its protection level, and relates to the material obtained by this method. The invention also relates to a second alternative configuration and production steps of said composite texture. With said alternative configuration, the same fiber contents in general terms are used in a different order, and the lamination of the layers is provided by epoxy and phenolic resins.

State of the Art In the international arena, defense industry is one of the factors determining the power of countries in the economic and political fields. Along with the technological developments, innovation and modernization are continuously needed in the defense industry. Defense industry is in interaction with many sectors. These can be classified as; aviation and space, military shipbuilding, rocket and missile, weapons and ammunition, electronics, military automotive and armored vehicle, military clothing.

The use of advanced composites in liquid armors, unmanned aerial vehicles, tank and aircraft armors, wing and tail elements of aircrafts and landing and take-off runways, contributes significantly to the development of the defense industry. Composite material; is a group of materials that is formed by combining at least two different substances for a specific purpose. In this three-dimensional combination, the aim is to achieve a property that does not exist alone in any of the components individually. In other words, it is aimed by the intended direction to produce a material with superior properties than its components.

As the varieties of weapon and ammunition is advanced, the protection technology required to counteract them is advanced at the same speed. The usage areas of ballistic protectors are increasing and studies are conducted on such protectors.

The materials used in ballistic protector production can be divided into three main groups, namely hard materials, soft materials and resins. Composite protectors are obtained with different combinations of these three main material groups. Ceramics, glass and metals are used as hard protective materials. Para-aramid, polyethylene, glass fiber are used as soft protective materials.

The most commonly used type of hard materials is ceramic. The ballistic performance of any type of ceramic is determined by the hardness of the ceramic. The density of ceramics determines the weight of the ceramic required for any area of use. Ceramics with low density and high hardness have higher ballistic performance.

Steel plates with high hardness can also be used in ballistic protectors instead of ceramic plates. However, ceramics are generally preferred in body protectors, and since it is heavier, steel is used in areas where the weight does not affect the use due to its cheapness.

One type of hard protective materials is glass and polycarbonate plate combination. Transparent protectors can be obtained with glass and polycarbonate combinations.

The most commonly used types of soft materials are para-aramid and polyethylene.

The types of aramid fabrics derived from aromatic polyamide are para aramid fibers used in ballistic applications. Especially, kevlar(Trademark) in ballistic field is used widely in personal dress, boot production and in advanced composite production and is known for its high mechanical properties. Twaron(Trademark) fiber is another aramid class material used in the production of ballistic protective equipment. Twaron's tensile strength and elasticity module are lower than those of Kevlar.

High molecular weight polyethylenes (HMWPE) are known on the market as Spectra(Trademark) and Dyneema(Trademark). They are the lightest materials used in the armor industry with their low density. The production details of both products are different while they are produced by different manufacturers, whereas both are made of high performance polyethylene fiber.

Since Dyneema fiber is made of polyethylene and contains no aromatic chains or amides, it exhibits excellent resistance to water, moisture, many chemicals, UV rays and various microorganisms. Unlike other ballistic fibers, they do not swell or become hydrolyte in water, seawater or humid environments. Dyneema, also known as engineering fiber, has very high erosion resistance. The fact that the amount of energy required to pierce Dyneema fiber is higher than the energy amount required to pierce other fibers indicates that it is a suitable fiber for ballistic applications. At the same time, its sound transmitting rate is also excellent compared to other fibers. The ability to transmit sound at high speeds results in the distribution of impact energy over a wider area, in other words it leads to the reduction in trauma.

Apart from these, glass fibers, carbon fibers and basalt fibers are also widely used in ballistic structures.

Glasses are very sensitive to cracks and fractures because of their highly fragile character. However, when they are produced in small sizes and in fiber form, they lose above mentioned adverse features and have very good mechanical characteristics. They are cost efficient and their production process is very simple. Different types of glasses have different characteristics. E-glass is one of the most used materials in practice, it contains very little alkali and has superior electrical and mechanical characteristics. S-glass is a type with higher aluminum and magnesium oxide compared to E-glass, which brings along further superior mechanical characteristics. Carbon fibers are more expensive than glass fibers, but they significantly improve the tensile, creep, fatigue, abrasion resistance and toughness of the material. Furthermore, despite the fact that they have a lower expansion coefficient and molding shrinkages, their strength/weight and rigidity/weight ratios are quite good. Basalt fibers have higher chemical fastness compared to glass fibers and can be processed at high temperatures. The heat, sound and electrical insulation properties of these fibers are quite good. They have extremely high strength. According to the Mohs scale, it has high hardness such as from 5 to 9. This provides the basalt with a high abrasion resistance. With its high heat resistance and extremely good mechanical properties, basalt fiber has the characteristic to take the places of asbestos or expensive carbon fibers.

Another group of materials used in ballistic production apart from soft and hard materials are resins. Resins are; substances that are solid or semi-fluid, non crystalline, water insoluble; however, dissolvable in organic solvents, softened when heated, and are carrier systems. Each resin has different properties, these properties reflect the main characteristics of the composite by gaining strength when combined with other products used in composite systems.

Today, bullet proof plates or textiles produced for security purposes are very diverse. Basically the materials used are bullet resistant steel, industry ceramics, glass or fiber based materials. These materials are generally used in armored vehicles, armored shields, bullet proof vests. Bullet proof plates used in armored vehicles are usually made of steel or industrial ceramics. However, these materials need to be used in a very high thickness to resist high-caliber bullets, which leads to problems of high costs and taking up large space. The use of the same materials (steel and ceramic) in shields and bullet proof vests is not much preferred since they are heavy, bulky and expensive. Majorly fiber textiles, glass fiber reinforced plates, carbon fiber containing plates or similar fiber structure materials are used in the bullet proof vests. In the use of this type of composite structure, the first problem encountered is lifetime, the second one is not being resistant to high caliber bullets, and the other one is the need to use very thick material, which increases the bulkiness and decreases its usefulness. On the other hand, this type of materials is single use only. It is not possible to use them once and again.

In the state of the art, a USA patent with application number US2014/0060302 is encountered. Said patent discloses a structure which not only functions as bullet proof vest but also decreases the bullet impact speed for not reflecting the speed and momentum of the bullet to the user as a stiff impact.

In the state of the art, a USA patent with number US4413357 is encountered. Here disclosed is a structure trying to reduce the shock effect exerted by the flexible layer bullet to the ballistic layers.

In the state of the art, a USA patent with number US9644923 is encountered. In this patent, a protective glove or a similar garment is designed with fiber materials and steel mesh-wise materials.

In the state of the art, a USA patent with application number US2016/0187102 is encountered. It is seen in here that a bullet proof suit design in which plastic derivatives such as PET, PVC, PE, PP containing air gaps are used is disclosed.

In the state of the art, an international patent with application number W02009/047617 is encountered. Here disclosed is obtaining a separate bullet resistant plate or structure by combining layers in the fiber structures with different densities.

In the state of the art, an international patent with application number

W02006/103400 is encountered. In said patent, a structure where ceramics is used and also shock is absorbed by creating mechanical vibration is provided.

Technical Problems Intended to be Solved by the Present Invention In the subject matter bullet proof texture, a structure which is lighter relative to those in the state of the art, but able to resist to bullets of higher caliber fired arms is aimed to be achieved by combining different types of fiber structures with resin of materials such as basalt, ceramic fiber and UD fiber glass at different layers. A feature of the subject matter bullet proof texture is that the tissue is both wearable and can be used as a plate by using different types of fibers.

Another characteristic of the subject matter bullet proof texture is that the fibers used are in the form of fabric and are also shock absorbent since no metal plate is used.

The subject matter bullet proof composite texture will be produced by generally adding polyester vinyl resin and the following materials in it, and by using woven or non-woven fabric and glass fiber having high resistant. Production method and layers will generally be described for the production of a bullet proof plate. However, if desired, the material can be produced for clothing by making it thin and flexible or as plate or thick block by making it thicker. According to the shape of the material to be produced, preferably the production will be made with steel mold. In order that the composite materials do not stick to the mold, mold release agent should be applied to the mold, and after curing the resin (generally between 10-20 minutes), it will be removed from the mold. Mold dimensions will not be limited by the size since they vary from product to another product.

The subject matter bullet proof texture is treated by a process which is subjected to the operation specified in the following steps in accordance with the flow chart in Figure-1 .

- Resin preparation and application into the mold (10)

- First UD basalt fiber layer application (20)

- First UD glass fiber layer application (30)

- Ceram ic fiber fabric layer application (40)

- Aramid fiber layer application (50)

- Polyethylene fiber Layer application (60)

- Second UD glass fiber layer application (70)

- Second UD basalt fiber layer application (80)

- Keeping under pressure (90)

- Baking (100)

- Outer cover coating (110)

The texture shown schematically in Figure-2 will be obtained by applying the above production process of the subject matter bullet proof composite texture. This texture is generally bullet proof plate. However, it can be produced as wearable or it can be produced in the form of plate for armor.

A detailed description of the process steps is given below. In the description, the percentage and per thousand indications will be as 100:x and 1000:x. Such as 100:5, 100:10, 1000:15.

Resin mixture preparation and application into the mold (10)

At this stage, ilkalem (trademark name) PV-300 vinyl ester resin is mixed with P- 1020 polyester resin in a ratio of 100:7-100:15, preferably 100:10, for 2 to 10 minutes, preferably 5 minutes. Then nanographen is added in the ratio of 100:3- 100:7, preferably 100:5, and mixed again for 2 to 10 minutes, preferably 5 minutes. Liquid cobalt is added to this mixture in a ratio of 1000:2-1000:10, preferably 1000:2, and mixed for 3 to 8 minutes, preferably 5 minutes, and then waited for 2 to 7 minutes, preferably 5 minutes. After said process, a freezer accelerator mek is added into the resin in a ratio of 100:1-100:10, preferably 100:2, and mixed for 3 to 8 minutes, preferably 5 minutes. The resin is left to stand until foaming of it stops, this process takes between 5 and 15 minutes, preferably 10 minutes. At the end of this process, the resin to be used in production becomes ready. Said resin is applied into the mold on which mold release agent is already applied. First UD basalt fiber layer application (20)

Basalt fiber cut as the mold size is put into the mold and the resin prepared earlier is spread with a brush. After the basalt fiber has finished absorbing the polyester vinyl ester resin mixture, the next step is performed.

First UD glass fiber layer application (30) Glass fiber cut as the mold size is laid in the mold and resin is applied on it and fed. Herein, preferably S Glass glass fiber will be used. Absorption of polyester vinyl ester resin is ensured. Ceramic fiber fabric layer application (40)

Ceramic fiber fabric is cut as the size of the mold and laid on the glass fiber, which is laid previously, and polyester vinyl ester resin is applied and fed on it. Absorption of the resin is ensured.

Aramid fiber layer application (50)

Aram id fiber fabric type material is cut as the mold size and laid on the ceramic fiber fabric layer. It is preferred to use KEVLAR (Trademark) on the market as aramid fiber fabric. Herein, material types known as aramid softsteel will preferably be used as aramid. Polyester vinyl ester resin is applied and fed on aramid fiber fabric. Absorption of the resin is ensured.

Polyethylene fiber layer application (60)

In the mold, polyethylene fiber is applied on the aramid fiber layer. Application of DYNEEMA (Trademark) is preferred as polyethylene fiber in the market. Preferably, commercially available UHMWPE Dyneema (Trademark) fabric is laid and the polyester vinyl ester resin process is repeated.

Second UD glass fiber layer application (70)

After the polyethylene fiber layer applied to the mold in the previous stage, glass fiber is applied for the second time and again the resining process is carried out. Namely, polyester vinyl ester resin is applied and fed on the fabric.

Second UD basalt fiber layer application (80)

As the last layer for the mold, the second basalt fiber is added to the mold in a manner to be cut as the size of the mold, and it is completed by the last resining process, that is, by applying polyester vinyl ester resin on it. Then, the mold onto which mold release agent is applied is closed.

Keeping under pressure (100) By closing the upper part of the mold, a sufficient pressure, preferably an average pressure of 125 kg for a plate sized 25x30, can be applied depending on the desired wall thickness, weight and protection coefficient. A pressure that varies according to this size and thickness is applied on the mold. The mold is kept at a temperature of 24-30 centigrade degrees, preferably at 25° degrees for 10 to 15 hours, preferably 12 hours, to complete the curing process.

Baking (100)

After the layers are combined by means of resin and kept under pressure, they are kiln-dried at 100 C° and 400 C° for 5-25 minutes. In this process, different temperature and time is used depending on the volume and surface area of the product. For example, for Kuyag (Trademark) Breast Protection Plate, approximately temperature of 150-300 centigrade, preferably 200 degrees and a time period of 10-20 minutes, preferably 15 minutes are applied.

Outer cover coating (110)

When a structure that becomes a bullet proof composite texture is desired, an outer cover coating can be applied as a preference. This application can be performed by resin as well as baly or byson derivatives, preferably byson, and also strong fabric and leather adhesive types can be applied. For example, if an armor is made for personal use, leather coating or other patterned or plain fabric or plastic, composite or metal coating is applied. Flerein, hard leathers such as pork, iguana or ray can preferably be used here as vegetal. In the outer cover coating, if the armor to be produced is designed to be on a material, all these steps are performed on the material without using a mold. Furthermore, if they are provided to be produced as a clothing product, they can be obtained by sewing the fabrics used in said order. The weaving density, yarn twist and basis weight in centimeter square of all fabrics used vary depending on the type of armor and protection to be produced. Furthermore at the end of the step of keeping under pressure (90), carbon fiber coating can be made optionally and then baking (100) step can be started. Carbon fiber coating (b) is performed by coating the portions, having wall thickness, of the product taken out of the mold, as shown in Fig. 2, with the carbon fiber fabric by heating with polyester vinyl ester resin. We need to wait 10 to 15 hours (preferably 12 hours) for the resin to dry. Carbon fiber coating (b) is optional and its purpose is to increase the resistance of the lamination.

Perspective top view of the bullet proof composite texture (a) obtained according to the above-mentioned steps is shown in Figure-2. Figure-3 shows a side cross section of the subject matter bullet proof composite texture (a). As shown in Figure- 3, the subject matter bullet proof composite texture (a) comprises (contains), respectively, the first UD basalt fiber layer (d), the first UD glass fiber layer (e), ceramic fiber fabric layer (f), Aram id (Kevlar) fiber fabric layer (g) the polyethylene fiber (Dyneema) layer (h), the second UD glass fiber layer (i) and finally the second UD basalt fiber layer (j). When desired, coatings such as leather coating can also be made for the appearance. But, this is optional. Of course, these layers are combined with the prepared polyester vinyl ester resin. Therefore, there is resin between them. The subject matter bullet proof composite texture (a) includes at least one of each said layers. Although each layer is shown as one layer in the illustration of Figure- 3, it may be possible to use more than one layer according to the level of protection. The subject matter bullet proof composite texture (a) is preferably suitable to be maximum 28 layers. Flaving more than 28 layers will bring the state of the art problems such as weight, bulkiness and taking up much space.

The maximum number of layers that can be used for each layer is given in the table below.

According to the above table, the first UD basalt fiber layer (d) and the second UD basalt fiber layer (j); can be used such that their number of layers will be in total maximum 5. It is preferred that the weight is on the first UD basalt fiber layer (d). The reason of this is that the side receiving the bullet is the first UD basalt fiber layer (d).

The first UD glass fiber layer (e) and the second UD glass fiber layer (i); can be used such that their number of layers will be in total maximum 11. Analogously, it is preferred here that the first UD glass fiber layer (e) is the weighted one. The first UD glass fiber layer (e) is the side receiving the bullet.

It is preferred to use ceramic fiber fabric layer (f) at maximum of 2 layers, Aramid fiber layer (g) at maximum of 7 layers and polyethylene fiber layer (h) at maximum of 3 layers.

A second alternative bullet proof composite texture (k) consists of the ceramic plate layer (I), UD basalt fiber layer (m), UD glass fiber layer (n), Aramid fiber layer (o), Polyethylene fiber (Dyneema) layer (p), second UD glass fiber layer (q) and the second UD basalt fiber layer (r) which are generally combined with phenolic resin.

A subject matter secondary alternative bullet proof composite texture embodiment (k) can be achieved by the following steps given in Figure-4. In this process, the aramid fiber layer (o) is in the form of multiple layers. The aramid layer (o) may consist of 10 to 20 sublayers (s). Other layers are one layer.

- Preparation of phenolic resin and epoxy resin (120)

- Ceramic plate layer application (130)

- First UD basalt fiber layer application (140)

- First UD glass fiber layer application (150)

- Aramid fiber layer application (160)

- Polyethylene fiber layer application (170)

- Second UD glass fiber layer application (180)

- Second UD basalt fiber layer application (190)

- Keeping under pressure (200)

- Baking (210)

- Outer cover coating (220)

The production process for a subject matter secondary alternative bullet proof composite texture embodiment (k) is examined in detail below.

Preparation of phenolic resin and epoxy resin and applying phenolic resin onto the mold (120) In the subject matter secondary alternative bullet proof composite texture embodiment (k), two different resins as epoxy resin (t) and phenolic resin will be used. The epoxy resin (t) will be used for the lamination of the aramid layer (o) between itself, and the phenolic resin for the lamination of the other main layers. Phenolic resin mixture to be prepared for the subject matter secondary alternative bullet proof composite texture embodiment (k) contains; phenolic resin in the ratio of 100:30-100:35, hardener in the ratio of 100:2-100:5, accelerator in the ratio of 100:2-100:5, thickener in the ratio of 100:2-100:3. Furthermore, in the preferred embodiment of the invention, the mold release agent is also added in the ratio of 100: 1 -100:2. Zinc stearate will be used as mold release agent; Magnesium hydrate, calcium hydrate, calcium oxide and magnesium oxide will be used as thickener.

Epoxy resin mixture (t) will be prepared such that it contains epoxy resin in the ratio of 100:25-100:30, hardener in the ratio of 100:1-100:3, accelerator in the ratio of 100:2-100:5, filler in the ratio of 100:5-100:10, thickener in the ratio of 100:1-100:2. The accelerator and hardener are first mixed together homogeneously and added to the epoxy resin. Then other additives are added to the said mixture. Unlike the phenolic resin; the mold release agent will not be added and the thermoplastic hollow microspheres (u) will be used as filler.

Thermoplastic hollow microspheres (u) are thermoplastics surrounding gas molecules. When heated, gas molecules (w) expand by the influence of temperature, and the thermoplastic (v) softens. This causes microspheres (u) to grow in volume. Advantage of this is that there is an increase in volume while there is no increase in terms of mass. Figure-7 and Figure-8 show representative images of thermoplastic microspheres (u) before and after heating. Phenolic resin prepared as the first stage in the production process of a secondary alternative bullet proof composite texture embodiment (k) is applied onto the mold.

Ceramic plate layer application (130) In the ceramic plate layer application step, the ceramic plate layer (I) is put into the mold. The previously prepared phenolic resin is fed onto it with the help of a brush and proceeded to the next step. Tile or monolithic ceramics can preferably be used in ceramic plate layer application. First UD basalt fiber layer application (140)

In the first UD basalt fiber layer application step, basalt fiber (m) cut as the size of the mold is laid on the ceramic plate layer (1) and phenolic resin is applied and fed on it.

First UD glass fiber layer application (150) In the first UD glass fiber layer (n) application, glass fiber cut as the size of the mold is laid in the mold and phenolic resin is applied and fed on it. Glass fiber of type S glass will be used here.

Aramid fiber layer application (160)

Aram id fiber fabric (o) type material is cut as the mold size and laid on the the first UD glass fiber layer (n). Epoxy resin (t) is applied and fed on it and then again a new aramid fiber (o) fabric is added. In this way, aramid fiber fabric sublayer (s) from 10 to 20 pieces are laminated with epoxy resin (t). In said structure, Kevlar (Trademark) will be used as aramid. Herein, material types known as aramid softsteel will preferably be used as aramid. Phenolic resin is applied and fed on the last aramid fiber sublayer (s). The resin is absorbed.

Polyethylene fiber layer application (170)

In the mold, polyethylene fiber (p) is applied on the aramid fiber layer (o). Application of DYNEEMA (Trademark) is preferred as polyethylene fiber in the market. Preferably, commercially available UHMWPE Dyneema (Trademark) fabric is laid and the phenolic resining process is repeated.

Second UD glass fiber layer application (180) After the polyethylene fiber layer (p) applied to the mold in the previous stage, UD glass fiber is applied for the second time and again the resining process is carried out. Namely, phenolic resin is applied and fed on the fabric. Second UD basalt fiber layer application (190)

As the last layer for the mold, the second basalt fiber is added to the mold in a manner to be cut as the size of the mold, and it is completed by the last resining process. Then, the mold onto which mold release agent is applied is closed.

Keeping under pressure (200) By closing the upper part of the mold, a sufficient pressure, preferably an average pressure of 125 kg for a plate sized 25x30, can be applied depending on the desired wall thickness, weight and protection coefficient. A pressure that varies according to this size and thickness is applied on the mold. The mold is kept at a temperature of 24-30 centigrade degrees, preferably at 25° degrees for 10 to 15 hours, preferably 12 hours, to complete the curing process.

Baking (210)

Outer cover coating (220)

When a structure that becomes a bullet proof composite texture is desired, an outer cover coating can be applied as a preference. This application can be performed by resin as well as baly or byson derivatives, preferably byson, and also strong fabric and leather adhesive types can be applied. For example, if an armor is made for personal use, leather coating or other patterned or plain fabric or plastic, composite or metal coating is applied. Wherein, hard leathers such as pork, iguana or ray can preferably be used here as vegetal. In the outer cover coating, if the armor to be produced is designed to be on a material, all these steps are performed on the material without using a mold. Furthermore, if they are provided to be produced as a clothing product, they can be obtained by sewing the fabrics used in said order. The weaving density, yarn twist and basis weight in centimeter square of all fabrics used vary depending on the type of armor and protection to be produced.

A secondary alternative bullet proof composite texture embodiment (k) obtained according to the above mentioned steps is shown as a representation in Figure-5. Side cross section of a secondary alternative bullet proof composite texture embodiment (k) layers of which can also be seen is shown in Figure-6. Accordingly, the subject matter secondary alternative bullet proof composite texture embodiment (k) consists of, respectively, the ceramic plate layer (I), first UD basalt fiber layer (m), first UD glass fiber layer (n), Aramid fiber layer (o), Polyethylene fiber layer (p), second UD glass fiber layer (q) and finally the second UD basalt fiber layer (r). When desired, coatings such as leather coating can also be made for the appearance. But, this is optional. Of course, these layers are combined with the prepared resins. Therefore, there is resin between them. Phenolic resin is used between the main layers. Aramid layer consists of 10 to 20 aramid sublayers (s), lamination of these sublayers (s) is ensured by epoxy resin (t).
