Definitions
- the technical field of the present invention is that of the splinter coatings that we place behind the wall of an armored vehicle to decrease his vulnerability.
- the splinter coatings are mainly used today in vehicles armored personnel carriers or combat vehicles Infantry. Their function is to decrease the angle of the cone of flakes generated during the perforation of the armored vehicle with anti-tank projectile kinetic energy (arrow projectile) or especially jet of hollow charge. Having regard to the technical field concerned, we understands that there is very little data bibliographies describing these coatings.
- the object of the present invention is to offer a lightened splinter coating, offering a efficiency equivalent to that of solid coatings, but with a greatly reduced thickness, using materials with a density much lower than that metals.
- the subject of the invention is therefore a splinter-proof coating for armored vehicles comprising in particular a layer adherent of solid organic material arranged against the inner wall of the vehicle, an adjacent layer of a composite material with organic matrix and mineral reinforcement or organic placed in the immediate vicinity of the layer adherent, characterized in that it is inserted between the adherent layer and the adjacent layer an area of thickness dispersion between about 5 and 30 mm filled with a liquid or gaseous fluid, or a foam polystyrene or polyurethane.
- the adherent layer of solid organic material is chosen in the group consisting of polyethylene, the polypropylene, a plate of polyethylene filaments or of aramid, a rubber, and having a thickness between 2 and 45 mm.
- the splinter-proof coating comprises a absorbent layer of particles chosen from the group consisting of a matrix and binder composite material organic and a plastic film of thickness included between about 1 and 5 mm.
- the layer adjacent has a thickness of between about 2 and 30 mm.
- An advantage of the present invention lies in absorbing the splinters generated during the perforation of the vehicle wall without production secondary flakes and simultaneously reducing or total suppression of the phenomenon of flaking at the opposite side of the structure to the attack.
- Another advantage is the reduction in the size of the coating inside the vehicle.
- Another advantage is the capacity of the coating according to the invention to reduce the neutron flux, and absorb the heat flux transmitted by them projectile fragments brought to high temperature to thereby ensuring a flame retardant effect.
- FIG 1 there is shown in section the wall 1 of an armored vehicle or structure any splinters when it is damaged by a projectile coming from outside as this is symbolized by the arrow F.
- a first adherent layer 2 made of a material known chosen from the group constituted by the polyethylene, polypropylene, a plate of filaments of polyethylene or aramid, a rubber. Membership can for example be made by gluing using a glue or bolting.
- the thickness of this layer 2 is advantageously between 5 and 45 mm.
- the function of this layer due to the thickness chosen, is to limit and / or stop the large flakes produced behind wall 1 and get a first reduction of the dispersion angle of the this armored wall.
- this layer 2 ensures a decrease in the neutron flux inside of the vehicle in the event of a nuclear attack.
- the layer 2 is in the form of a plate of organic polyethylene or aramid filaments, we plays on the large dynamic deformation capacity of this material.
- This first layer is followed by a layer adjacent 3 which in combination with layer 2 stops the secondary flakes generated by the first layer and further reduces the scattering angle of the shards of the armored wall 1.
- This layer 3 consists of a composite material with organic matrix and mineral reinforcement with a thickness between 5 and 30 mm. The combination effects of layers 2 and 3 achieves with a markedly reduced thickness equivalent efficiency even higher than each of these layers taken in isolation, but with significantly more space important.
- This layer 4 is made up of composite materials organic matrix and organic binder and / or film plastic with high mechanical characteristics such as bi-stretched polyethylene.
- the thickness of this layer 4 is weak compared to that of the other two, for example from 1 to 5 mm.
- This layer 4 is applied, for example by gluing, on layer 3.
- This layer 5 can be a gas or a liquid, a foam polystyrene or polyurethane, including thickness between 5 and 30 mm approximately. The presence of this layer 5 is conditioned by the level of threat you want reduce.
- Figure 3 illustrates a variant of realization of the splinter-proof coating in which the layer 2 is replaced by two sublayers 2a and 2b.
- the sublayer 2b is of the same nature as layer 2 previous, that is to say that it is constituted by polyethylene, polypropylene, filament board of polyethylene or aramid, a rubber. This material has a good shock impedance. She can present a thickness between 2 and 30 mm.
- the underlay 2b consists of an organic matrix composite with reinforcements of mineral or organic fibers. The thickness of this layer 2b is of the order of 2 to 20 mm.
- the layer 5 which constitutes a dispersion zone can be made of polystyrene foam or polyurethane.
- the other two layers 3 and 4 remain identical to the previous ones.
- Puncture tests with a shaped charge have shown the excellent behavior of the splinter-proof coating obtained.
