Description

SPECIFICATION Protective shields This invention relates to protective shields.
Co-pending Application No. 2061089 disclosed a protective shield to be used in front of a person's body to protect such person against injury by a bullet or other missle, said shield comprising a supported layer of a rigid, brittle material having a high degree of hardness and a penetration-resisting and impact-absorbing backing structure on that side of the said supported layer which in use faces the person's body.
The specification of said Application specifically describes a relatively lightweight shield which can be worn by a person and is capable of providing effective protection against high velocity rifle bullets.
An object of the present invention is to provide a shield capable of providing even better protection with a relatively lightweight structure and which may be suitable for use, for example, as armour in military vehicles, for protecting against high energy missiles such as armour-penetrating bullets and shells.
According to the invention therefore there is provided a protective shield which comprises at least one laminated structure having a front lamina and a back lamina fixed together in superimposed relationship; said front lamina comprising a supported layer of a rigid, brittle material having a high degree of hardness and a penetration-resisting and impact-absorbing backing structure on the rear side of the said supported layer; and said back lamina comprising an energy-dispersing structure which is preferably a relatively rigid, readily disruptible structure.
With this arrangement, when a high energy missile strikes the said supported layer of the front lamina, energy can be absorbed as the brittle material shatters and the missile can be broken up due to the hardness of the material. The resulting fragments can then enter the backing structure to be stopped or at least slowed by the action of the penetration-resisting material. Fragments which have passed through this backing structure reach the back lamina which acts to disperse widely and dissipate remaining kinetic energy.
Thus, effective protection can be provided against high energy missiles. Moreover the diverse nature of the action of the shield is such that it may be capable of providing effective protection against different kinds of missiles; and, further, the construction of the shield is such that effective protection can be attained with a relatively low weight compared for example with conventional steel plate armour. Still further effective protection can be achieved without necessitating the use of large quantities of materials, such as metals, which can themselves produce dangerous spoil or shrapnel due to the heat and/or impact of the missile.
The protective shield of the invention may be used for any suitable purpose in any suitable context, although it is visualised that the shield will find particular application as armour for vehicles, especially military vehicles. When used as armour for vehicles, the shield may be attached to the outer or inner surface of the vehicle or alternatively and preferably may be incorporated in the vehicle surface for example by inclusion between inner and outer skins thereof.
With regard to the said front lamina of the shild, this may be constructed wholly or largely as described in the aforesaid Application No. 2061089.
Thus, the brittle material of the supported layer may comprise a glass or ceramic material preferably in the form of edge-to-edge plates and this may be supported by bonding or by otherwise holding same against a stiff or semi-stiff sheet made up of one or more layers of a closely-woven fabric which is made from aramid fibres of high tensile strength and high stretch resistance such as to be capable of resisting penetration by a bullet, particularly the aramid material sold by Du Pont under the trade name KEVLAR. The said backing structure may be in the form a sheet made up of one or more layers of such aramid fabric alone or if desired backed with one or more polycarbonate sheets and/or one or more sheets of impact-absorbing plastics material.In a particularly preferred embodiment of the present invention the support for the brittle material and the backing structure are formed by a common, stiff sheet made up of multiple layers of said aramid fabric laminated securely together for example by means of an adhesive.
With regard to the said back lamina of the shield of the present invention, this may have any suitable structure and may be formed from any suitable material. In one embodiment a contained layer of hard granular or particulate material is used, for example, a layer of ceramic fragments or chips. In an alternative embodiment a rigid cellular structure is used, for example, a self-supporting sheet of honeycomb material, or rigid foamed plastics or the like. It is even possible to use as said structure of said back lamina a hollow construction providing an air gap between spaced walls which can act as a disruptible expansion chamber.
The laminae of the shield of the invention may incorporate or be used in conjunction with auxiliary materials and structures as desired. Also, it is to be understood that the shield of the invention may comprise multiple said laminated structures arranged one behind the other.
The invention will now be described further by way of example only and with reference to the accompanying drawings, Figures 1 to 3, which are diagrammatic sectional views of different forms of protective shields according to the invention.
With reference to Figure 1, a protective shield incorporated between inner and outer skins 1, 2 of a vehicle comprises multiple laminated structures 3, 4, one behind the other. Each such structure 3, 4 comprises a front lamina 5 and a back lamina 6.
Only two structures 3, 4 are shown in the drawing but in practice more structures may be used as appropriate.
The front lamina 5 comprises a front layer of ce ramic plates 7 held securely in contact with a stiff backing layer 8, both such layers 7, 8 being enclosed within a sealed wrapping or bag 9.
The ceramic plates 7 are separate rectangular plates placed edge-to-edge and bonded to the backing layer 8 so as to define a rigidly supported substantially continuous ceramic sheet. The plates 7 may be about 7mm thick and may be formed from a silicon carbide or alumina or boron carbide ceramic, particularly a self-bonded silicon carbide manufactured and sold under the name REFEL by British Nuclear Fuels Limited. The plates 7 may be bonded to the backing layer 8 with a thick silicone rubber such as Berger Silicone 381.
The backing layer 8 is formed from multiple superimposed layers of the aramid fabric KEVLAR (say Kevlar 29 to 49 woven with 31-31 warp and weft picks per inch (2.54 cm) from 1000 to 1500 denier yarn). The layers are bonded together, for example, with the above-mentioned adhesive, to give a stiff board-like structure. Alternatively, it is possible to use aramid fabric containing thermoplastic yarns whereby the layers can be united by head-bonding.
The bag or wrapper 9 is formed from a single flexible sheet of nylon fabric or KEVLAR fabric of the kind described above and may be sealed and also fixed to the layers 7, 8 by bonding or heatsealing.
The back lamina 6 comprises a layer of looselyor tightly-packed fragments or chips 10 formed from a ceramic material such as that described above. These fragments or chips may be contained with a bag 11 or other container which bag is united, for example, by bonding with the bag or wrapper 9, or by enclosure of both the bag or wrapper 9 and the bag 11 within a common container. Alternatively the wrapper or bag 9 may also be used to contain the chips or fragments 10.In any case, the chips or fragments 10 of the front laminated structure 3 are contained between the backing layer 8 of such structure and the front lamina 5 of the next rearmost structure 4, and the chips of fragments 10 of the rearmost structure 4 are contained between the front lamina 5 of such structure 4 and a final backing layer 12, it being understood that all components of the shield are sandwiched securely and tightly together by virtue of an outer enclosing bag (not shown) and/or due to the mode of incorporation thereof between the skins 1,2 of the vehicle.
The final backing layer 12 may comprise an assembly of KEVLAR layers of stiff board-like structure of like form to the layers 8.
With this arrangement, when a high energy missile strikes the protective shield, the cermaic plates 7 of the foremost structure 3 shatter and act to fragment the missile. The resulting, slower moving fragments pass through the backing structure 8 and are much slowed by same. The slowed frag ments emerging from the structure 8 are further broken up and widely dispersed by the layer of ce ramic chips 10. This procedure is then repeated in the further layers of the shield.
The shield thereby provides effective protection against high energy missiles and it will be noted that this is achieved with a relatively lightweight structure (relative to steel armour of equivalent effectiveness) which when struck by a missile does not tend to produce hot or penetrating fragments (as can be the case with steel armour).
The arrangement of Figure 2 is similar to that of Figure 1 except that layers of hard, rigid plastics foam 13 are used in place of the ceramic chips or fragments, such foam, like other components of the shield being formed from a suitably flameproof material.
The arrangement of Figure 3 differs from that of Figure 1 in that air gaps 14 are utilised in place of the ceramic chips or fragments, such air gaps being defined between front and back walls with suitable spacing arrangements or materials 15 therebetween. Such walls may be defined by the pertaining layers 7, 8, 12 or, alternatively by specially provided structures.
It is of course to be understood that the invention is not intended to be restricted to the details of the above embodiments which are described by way of example only.
Thus, for example the shield of the invention is not restricted to use with armoured military vehicles but may also be used with caravans, or building structures or for any other suitable purpose.
Moreover, reference is made to Application No.
2061089 and also prior UK Patent 1,556,245 for further details of materials and structures which can be used in the present invention.
