- the fibers are unidirectional, depending on the plate -45 ° / +45 ° or unidirectional cutting available in 0 ° / 90 ° / 0 ° / 90 °.
- DE 724 202 A describes body protection with a movable protective device that does not hinder body movements.
- a protective compound made of a metal ring mesh consisting of light metal wire is sewn into the garment on a layer of fabric or cotton wool or into the fabric itself, which is adapted to the shape of the garment part and in which the wire ends of the individual ring links are connected by welding.
- Disadvantages of the invention mentioned include, among other things, that the metal rings are too large for optimal protection against cutting weapons, stabbing weapons and projectiles.
- the wire ends must be welded. This means that there are irregularities in the structure.
- a protection against strong forces such as B. from long weapons, or from thin weapons, such as. B. a stylet or a syringe is not available.
- the spatial design is also limited by the metal rings.
- the steel chain net can be formed as a flexible, stable mat by embedding it between two layers of thermoplastic material, which are fused together under pressure under the influence of heat.
- the steel chain net can be formed as a flexible, stable mat by embedding it between two layers of fabric coated with thermally activated glue, which are glued together by pressure under the influence of heat.
- the soft ballistic solutions such as those made from multi-layer textiles, only protect against handguns, but not against long weapons.
- plate solutions e.g. B. made of metal or ceramic.
- Plates are rigid, inflexible and very heavy in the higher protection classes, such as those required against long weapons. There are fewer protected areas between the plates. The breathability is almost non-existent. When you fall, get into position or come into contact with objects, plate solutions make noises, which can be caused by: B. can have an unfavorable effect in combat. Shaping is difficult with plate variants.
- EP 000002384248 Bl relates to a three-dimensional wire structure in lightweight construction, which consists of several wires that cross and are connected to one another to form a large number of cells in three-dimensional space.
- the invention is used, for example, in medical technology, vehicle and mechanical engineering as well as in construction.
- WO 2015/026258 Al refers to the area of wire mesh structures as well as fabrics with a special arrangement of threads.
- a three-dimensional network that includes a set of neighboring layers. Each layer is formed by two mutually orthogonal families of threads or rods. The axes of the threads or rods have the form of helixes twisted in opposite directions relative to the axes of the threads or rods of the other family. They are arranged in such a way that each thread or rod of one family encloses a thread or rod of the other family with every rotation and at the same time also adjoins it. enclosing bared threads or rods of his own family.
- the threads or rods of each layer are intertwined with the threads or rods of the adjacent layers. It is possible to form a combined net that additionally contains threads or rods arranged in the cavities of the net, the threads or rods being provided individually or by a conventional binding, such as. B. a plain weave, connected to each other.
- the invention can be used in the production of composite materials, in a number of building structures and original machine parts, as well as in the production of a number of consumer products: providing cool summer mattresses, eternally dry mats for baths and swimming pools, naturally convection-ventilated car seats and others.
- the object of the invention is to propose a flexible protective composite against cutting, stabbing and shooting weapons as well as splinters, consisting of a composite of soft-ballistic and hard-ballistic protective materials. This should have a low weight, a high level of flexibility and a low level of noise and should be easy to manufacture and use effectively with an easily possible and universal shape.
- the flexible protective composite according to the invention against cutting, stabbing and shooting weapons as well as splinters consists of a composite of soft-ballistic and hard-ballistic protective materials.
- the soft ballistic protective material is a multi-layer fabric made of high-strength textile materials.
- the hard ballistic protective material consists of a three-dimensional wire structure in lightweight construction, which consists of several cells that form a large number of three-dimensional cells. dimensional space crossing and interconnected wires.
- the three-dimensional wire structure (2) is formed in each level from interlocking transverse spirals (3) and longitudinal spirals (4). There are at least 2 levels provided, which are also connected to each other. The connection takes place in certain nodes, which again occurs through the interlocking of the transverse spirals (3) and longitudinal spirals (4), analogous to interlocking in a plane.
- the soft-ballistic and hard-ballistic protective materials are connected to each other in such a way that the individual layers are kept stable in their position.
- a sandwich structure is formed that is particularly flexible and universally applicable for a wide range of applications, especially for all types of protective vests.
- a further embodiment describes that the shape of the flexible protective composite is adapted to the external shapes of the people or objects to be protected, or at least parts thereof.
- the flexible protective composite can be dimensioned differently and thus offers people, animals and objects protection against harmful influences, such as punctures, cuts, splinters, handguns, long guns and the like.
- the solution offers a clear weight advantage, is not rigid and does not offer any weak points in the overall structure.
- the shape can be any desired without affecting the protection.
- the flexible protective composite obtained has a low weight, high flexibility and low noise and can be used with an easy and universal shape.
- Fig. 1 shows a flexible protective composite, which is designed in a sandwich construction and in which the soft ballistic protective material arranged on both sides is a multi-layer fabric 1, which consists of high-strength, textile materials.
- High-strength polyethylene threads serve as the basis. The threads are stretched and placed parallel to each other without being connected to each other.
- a layer 9 is created consisting of a group of threads. The fixation takes place through material connection or mechanically through friction and/or positive connection. Depending on the intended use, additional layers 9 are placed on this group of threads according to the same principle. To achieve a certain property in several directions, the thread sheets are laid at different angles to the production direction.
- Figure 2 shows the manufacturing process schematically with fixation by sewing using a needle 10 and a sewing thread 11.
- 50 layers can be connected to one another by sewing on a saddlery machine, a sewing needle with a thickness of Nm 200 of the needle system 70, 4, using a sewing thread with a fineness of Nm 20/3 and a stitch length of 5 mm.
- a hard ballistic protective material is provided between the two soft ballistic surfaces. This is formed from a three-dimensional wire structure 2 in lightweight construction.
- the hard ballistic layer consists of several metal meshes made of wires 8 that cross over each other to form a large number of cells in three-dimensional space.
- a wire 8, e.g. B. made of stainless steel 1. 4567, with a wire diameter of, for example, 0.63 mm, formed into spirals and connected to each other by screwing. At the end there is a braid that is shifted three times into one another.
- Figs. 3 and 4 show the three-dimensional wire structure in lightweight construction. This consists of a large number of helically wound, crossing each other to form cells 7 in three-dimensional space. of the connected wires 8, which are arranged in alternating orientation of their axes and different planes.
- Fig. 3 shows a wire structure composed of two levels, which can be expanded to include additional levels in the third direction.
- helical wires 8 running parallel with their axes to one another are designed as a transverse spiral 3 by overlapping at their respective crossing points to form a wire mesh positively connected in the x and y directions, in which two adjacent wires pass over a crossing point 13 each turn is connected.
- the wire mesh can be expanded as desired in the y direction. The length of the wires used results in the expansion in the x direction.
- transverse to the axes of the transverse spirals 3 several helical wires 8 running parallel to one another with their axes are provided as longitudinal spirals 4, which overlap each other within the first plane at their crossing points as well as with the crossing points of the transverse spirals 3.
- longitudinal spirals 4 which overlap each other within the first plane at their crossing points as well as with the crossing points of the transverse spirals 3.
- four wires are in contact with each other at four crossing points, each of which forms a fully-fledged crossing point in the sense of this structure.
- a cell 7 of this level is bounded by four nodes.
- connection points are created by intertwining the transverse spirals of one level with the longitudinal spirals of the other level(s). These connection points form a small knot 6.
- the wire mesh of the first level is thus connected to the wire mesh Braid of the second levels connected congruently in the z direction.
- This structure is reinforced by adding additional levels. This causes the inserted cells to shift into one another in such a way that the cell sizes become smaller because there is more material.
- a further multi-layer fabric 1 made of high-strength polyethylene threads can be used as a third component. This is also cut into pieces measuring 500 mm x 500 mm to produce a flexible protective composite with the settings listed. 110 cuts of the HB 210 fabric are placed on top of each other and the individual cuts are rotated by 45 °. Viewed individually, the 110 blanks are stacked alternately at 0°, 45°, 90° and 135° on top of each other. This ensures the same properties of the fabric in all directions.
- the flexible protective composite according to the invention can be used universally against cutting, stabbing and shooting weapons as well as splinters.
- the positions of the segments and their size depend on the application. Shaped segments, such as those suitable for the shoulder, among others, can be produced in a simple manner due to their flexible formability. Larger segments up to a complete vest are also possible without the need for plate carriers, over vests and the like. Since a protective composite produced is very flexible and lightweight, it can be made larger than conventional, rigid plate solutions, especially for protective vests. This means that the possible body protection can also be extended to more lateral parts of the body without the people being protected having to experience any restrictions on movement. Depending on the desired protection class, the segments can be thinner and more flexible or thicker. In the case of armored vehicles for land, water and air use as well as drones, the armor can also be done using a protective composite according to the invention.
- segments When used to protect walls, tents, containers or mobile garages against projectiles or splinters, e.g. B. 2.50 m x 2.00 m segments are produced. If necessary, these segments are provided with a carrying handle. This structure serves as a portable protective wall or shield and can also be of other sizes. Mobile garages or containers can be made from several of these segments. To do this, the segments are set up as walls and one is used as a roof. These can then be firmly connected to each other using adhesives or other connection technologies. The individual segments can also be used directly as a tent, tarpaulin or cover.
- the flexible protective composites are low in weight and highly flexible. When used, these are characterized by low noise levels. They are easy to manufacture with a universal shape and can be used simply and effectively. Reference symbol layout
