Definitions
- the present invention relates to a structure for making ballistic protections, in particular, a multilayer structure that combines separate rigid elements.
- textile structures that stop bullets fired from a gun; they are mainly made of fibers having high breaking strength and textile structures that include, for example: weft-and-warp fabric, unidirectional fabric, multiaxial fabric etc. These structures can be used for making rigid or flexible ballistic protections, in accordance with the type of the bullet to be stopped.
- Flexible structures are mainly used in civil or para-military fields for the protection against the bullets fired by hand-guns. Such bullets are easily deformable and consequently, are easier to be stopped, also the correlated energy and speed are generally lower than about 1500 Joules and 500 m/sec.
- the trauma is controlled by the soft structure, where only the rigid structure is used, the trauma induced by the bullet fired from a rifle widely exceeds the prescribed value.
- a ballistic protection comprising a plurality of separate rigid elements, cooperating and not joint with each other, each of the rigid elements including a plurality of layers of high molecular weight polymers, wherein at least a part of the plurality of layers of high molecular weight polymers of at least one of the rigid elements includes laminates of high molecular weight polyethylene tapes or strips in the form of unidirectional leaves; at least a part of the plurality of layers of high molecular weight polymers of at least one of the rigid elements includes resin-impregnated fibrous laminates made of high molecular weight polyethylene fibers; characterized in that: the weight per unit of surface area of the first rigid element with respect to the direction of the incident bullet is greater than the weight per unit of surface area of the rigid element or rigid elements that follow the first one; and the value of specific bending modulus of the first rigid element with respect to the direction of the incident bullet is smaller than the specific
- the weight per unit of surface area of the rigid elements is decreasing starting from the first rigid element with respect to the direction of the incident bullet. Furthermore, advantageously, the value of the specific bending modulus of the rigid elements is increasing starting from the first rigid element with respect to the direction of the incident bullet.
- the ballistic protection according to the present invention has the advantage that the structures composed of elements which are poorly performing from the ballistic point of view, such as, for example, elements made of high molecular weight polyethylene strips or tapes, if introduced in non monolithic structures, allow a drastic reduction of the value of trauma without jeopardizing the bullet stopping capability.
- the value of trauma induced by the bullet impact is at least 20% lower with respect to the value of trauma induced by the bullet to a structure having the same composition, but monolithic.
- the use of elements which are less performing from the ballistic point of view brings about another advantage that derives from the cost reduction due to better efficiency in the production of tape or strips as compared with the yarn production costs.
- the rigid element including fibrous laminates made of high molecular weight polyethylene fibers is located on the side facing the direction of an incident bullet.
- the laminates of high molecular weight polyethylene tapes or strips in the form of unidirectional leaves are placed in such a way that the unidirectional leaves of one layer are inclined at about 90° with respect to the leaves of the next layer, and the single layers have at least one adhesive-covered face.
- each element in order to obtain the necessary rigidity, is individually pressed with a pressure between 1 and 300 Bar and at a temperature of between 50°C and 200°C.
- the textile elements are wholly or partially impregnated with one or more of the following: thermoplastic, thermosetting, elastomeric, viscous or viscoelastic polymers.
- the ballistic protection includes at least one ceramic element, likewise integrated in a polymeric structure and located outside and before the first rigid element with respect to the direction of the incident bullet.
- a ballistic protective article including the above described ballistic protection.
- the present invention allows a ballistic protection structure to be produced with a high resistance to piercing and reduced deformation (with consequent trauma), but at the same time, having a limited weight, by elimination of non ballistic elements. Furthermore, a protective element according to the invention achieves a trauma reduction without compromising the incident bullets stop capability and, at the same time, allows the protection weight and cost to be reduced.
- Figure 1 is a schematic, vertical section view of a structure for making ballistic protections according to a possible embodiment of the present invention
- Figure 2 is a schematic, vertical section view of a structure for making ballistic protections according to a possible alternative embodiment.
- a ballistic protection for personal protection includes a plurality of rigid structures, separated from one another, in which at least one rigid element includes layering of leaves made by high molecular weight polyethylene tapes arranged in parallel and unidirectional fashion, wherein these leaves are cross- plied and pressed at high temperature with adhesive polymers being laid down on at least one face of the single leaves, and in which at least another rigid element includes a layering of unidirectional resin-impregnated yarns, wherein each layer of unidirectional yarn is crossed with the subsequent one and subjected to a temperature and pressure action.
- the rigid structure which is the first to be impacted by the bullet, is made of a rigid element composed of ultra high molecular weight polyethylene yarn.
- the values of trauma obtained by the bullet impact are considerably reduced with respect to a monolithic layering of the same weight.
- the ballistic protection according to the present invention includes at least two rigid layers, separated, cooperating and not joint one with another.
- the weight per unit of surface area of the rigid element placed as first on the direction of the incident bullet i.e. which is the first to be impacted by the bullet
- the weight per unit of surface area of the rigid element placed as first on the direction of the incident bullet is greater than the weight per unit of surface area of the other subsequent rigid element or elements;
- the specific bending modulus value of the rigid element, which is the first to be impacted by the bullet is smaller than the specific bending modulus of the subsequent rigid element or elements.
- the ballistic protection includes at least two separate rigid elements, in which the weight per unit of surface area of the first element, which is impacted by the bullet, is greater than the specific weight per unit of surface area of all the other elements: the specific weight per unit of surface area of the element that follows the first one is comprised between 95% and 5% with respect to the first one.
- Figure 1 represents a ballistic protection according to an embodiment of the present invention which includes a first rigid element 101 and a second rigid element 103.
- a possible alternative embodiment, including three rigid elements 101 , 103 and 105 is represented in Figure 2 ( Figure 2 also shows an optional ceramic element which will be discussed in the following).
- the weight per unit of surface area of the rigid element that follows the first one is between 70% and 20% with respect to the weight per unit of surface area of the first element.
- the thickness of the first element is higher than the thickness of all the others.
- the weight per unit of surface area of the second rigid element is between 95% to 5% of the weight per unit of surface area of the first element, preferably between 70% and 20%; the weight per unit of surface area of the third rigid element is between 95% and 5% with respect to the weight of the first rigid element.
- the weight per unit of surface area of the first element is 13 kg/m 2
- the weight per unit of surface area of the second element is 3.5 kg/m 2
- that of the third element is 2.5 kg/m 2 .
- the weight per unit of surface area of the first element is 13 kg/m 2
- the weight per unit of surface area of the second rigid element is 1.5 kg/m 2
- the weight per unit of surface area of the third rigid element is 3.5 kg/m 2 .
- the specific bending modulus of the rigid element which is the first to be impacted by the bullet, is at least 10% lower than the specific bending modulus of the subsequent element or elements.
- the specific bending moduli are increasing beginning from the first element up to the last one.
- Typical values of the modulus of rigid laminates based on fibrous materials are in the range of 50 to 150 ksi, typical values of specific bending modulus of laminates based on tapes or plates are in the range of 200 to 400 ksi.
- the first rigid element is formed by a textile element made of yarns having tensile strength higher than 10 g/den, elongation to rupture higher than 1 % and tensile strength modulus higher than 40 GPa.
- Such first rigid textile element preferably includes UHMW polyethylene fibers, such as, for example, fibers of Spectra or Dyneema type, having the molecular weight greater than 500,000. In a preferred embodiment, the molecular weight is higher than 2,000,000 (two million).
- These fibers are preferably impregnated with thermoplastic elastomeric resins, for example, of Kraton ® type and then laminated to realize a continuous sheet with bidirectional structure, cross-plied, for example at 0 90° or +/- 45°.
- These laminates include laminates known as, for example, HB50 Dyneema ® or Spectra 3137 ® . Some of these leaves, also mixed as to weight and quality, are superimposed and consolidated with a pressure generally comprised between 1 and 300 Bar and preferably at a temperature in the range of 50 to 200°C.
