Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to protection scope of the present invention.
The Ceramic Composite the armour below embodiment of the present invention being provided is described in detail.
As shown in Figure 1 to Figure 3, a kind of Ceramic Composite armour, its concrete structure can comprise: shellproof backboard 1 and be located at the bulletproof ceramic piece 2 on shellproof backboard 1; Bulletproof ceramic piece 2 forms by plane plate 21 and for the curve tab 22 that changes bullet impact direction; Curve tab 22 is located at the upper surface of plane plate 21; The lower surface of plane plate 21 is fixed on shellproof backboard 1 in the mode of face contact.
Particularly, this Ceramic Composite armour can comprise following specific embodiments:
(1) curve tab 22 can adopt the various shapes such as spherical crown, cylinder, circular cone, prism or irregular curved surface, but preferably adopts the curve tab 22 of spherical crown shape; This is because the impact kinetic energy that weakens bullet is not only in the effect of curve tab 22, the more important thing is the impact direction that changes bullet, thereby makes bullet a large amount of consumed energies in migration process, to obtain the bulletproof effect far above existing shellproof equipment; Each position on spherical crown surface is all to have certain radian, all can there is certain deviation from the curve tab 22 of all angles contact spherical crown shape in bullet, and all there is certain dead angle in the curve tab 22 of other shapes, bullet can not be offset contact the curve tab 22 of other shapes during from dead angle, and this just cannot obtain good bulletproof effect.
In actual applications, the spherical crown height of the curve tab 22 of spherical crown shape is preferably between 1mm～8mm, and the radius of this spherical crown place spheroid is preferably between 1mm～25mm, can make like this base area of spherical crown be of moderate size, can, for bullet penetration provides a good resistance, can effectively change again the impact direction of bullet.Because the base area of spherical crown is larger, corresponding centre of sphere angle, spherical crown surface is less, the bending degree on spherical crown surface is less, the deviation angle of bullet is also just less, therefore in the time that the base area of spherical crown is excessive, probably cause bullet that skew or seldom skew do not occur, this can reduce the ballistic performance of whole bulletproof ceramic piece 2 greatly.And in the time that the base area of spherical crown is too small, the volume of spherical crown is too small, the good resistance that prevents bullet penetration not only cannot be provided, and cannot provide enough support forces to make bullet change impact direction, this also can reduce the ballistic performance of whole bulletproof ceramic piece 2 greatly.
(2) the set curve tab 22 of the upper surface of plane plate 21 can comprise following layout type:
1. curve tab 22 is a spherical crown, and the edge of the upper surface of the edge of this spherical crown and plane plate 21 is tangent.The bulletproof ceramic piece 2 of this layout type can make the impact direction generation certain deviation of bullet, therefore can play the bulletproof effect that is better than prior art, but its degrees of offset is not very large, and two bulletproof ceramic piece 2 joints can not be offset, therefore the bulletproof effect of this layout type is lower than following layout type described in 2..
2. curve tab 22 is multiple, and each complete curve tab 22 is all spherical crowns that size is identical; These curve tab 22 are distributed on the upper surface of plane plate 21, and are staggered between adjacent two row's curve tab 22; If curve tab 22 rankings are in the edge of the upper surface of plane plate 21, and space herein cannot arrange complete curve tab 22, and the curve tab 22 of part is only set so herein.
Wherein, thus part curve tab 22 refer to complete spherical curve tab 22 by the side of plane plate 21 cut formation, a part of curve tab 22 that the space of the edge of the upper surface of plane plate 21 can be placed.
Due in each bulletproof ceramic piece 2, the edge of the upper surface of plane plate 21 is equipped with the curve tab 22 of complete curve tab 22 or part, therefore in the time that two bulletproof ceramic pieces 2 engage, its joint has at least the edge of a side bulletproof ceramic piece 2 to be provided with curve tab 22, and this curve tab 22 can make the local thickness of stitching portion increase, thereby increase caking property and stress wave transitivity between bulletproof ceramic piece 2 and bulletproof ceramic piece 2, reached the object that improves two bulletproof ceramic piece 2 joint ballistic performances.
(3) preferably elder generation's one in mould is compressing for the plane plate 21 of bulletproof ceramic piece 2 and curve tab 22, then the integral structure that sintering forms, this can improve the support force of plane plate 21 to curve tab 22, thereby has improved the bulletproof effect of whole bulletproof ceramic piece 2.
(4) bulletproof ceramic piece 2 is multiple, and these bulletproof ceramic pieces 2 are preferably closely arranged on shellproof backboard 1 regularly, this can make shellproof backboard 1 all be covered by bulletproof ceramic piece 2, and can not leave space, therefore can make each position of whole Ceramic Composite armour all there is good ballistic performance.These bulletproof ceramic pieces 2 can be fixed on shellproof backboard 1 by adhesive 3, and the lower surface of the plane plate 21 of bulletproof ceramic piece 2 is preferably fixed on shellproof backboard 1 in the mode of face contact, this can make whole bulletproof ceramic piece 2 obtain the powerful support of shellproof backboard 1, thereby can change largely the impact direction of bullet, and effectively weaken the penetration power of bullet.
(5) can to adopt bottom surface be the prism of rectangle, trapezoidal, rhombus or parallelogram to the plane plate 21 of each complete bulletproof ceramic piece 2, but preferably all adopting bottom surface is square or orthohexagonal prism, and on same shellproof backboard 1, the shape of the plane plate 21 of each complete bulletproof ceramic piece 2 is preferably all identical, this contributes to bulletproof ceramic piece 2 layout on shellproof backboard 1, so that shellproof backboard 1 all covers by bulletproof ceramic piece 2, and do not interspace.
If 2 rankings of bulletproof ceramic piece are in the edge of shellproof backboard 1, and space herein cannot arrange complete bulletproof ceramic piece 2, the bulletproof ceramic piece 2 that part is only set so herein, this is in order to ensure that shellproof backboard 1 is all covered by bulletproof ceramic piece 2, and does not interspace.Wherein, thus part bulletproof ceramic piece 2 refer to complete bulletproof ceramic piece 2 by the edge of shellproof backboard 1 cut formation, a part of bulletproof ceramic piece 2 that the space of the edge of shellproof backboard 1 can be placed.
In actual applications, the thickness of shellproof backboard 1 is preferably between 4mm～24mm, this not only can make shellproof backboard 1 have an ability that prevents preferably bullet penetration, and can provide strong support force for bulletproof ceramic piece 2, thereby make bulletproof ceramic piece 2 weaken preferably the impact kinetic energy of bullet, and farthest changed the impact direction of bullet.The bottom surface length of side of the plane plate 21 of each bulletproof ceramic piece 2 is preferably all between 25mm～100mm, the thickness of the plane plate 21 of each bulletproof ceramic piece 2 is preferably all between 4mm～15mm, this not only can make surface plate piece 21 have an ability that prevents preferably bullet penetration, and can provide strong support force for curve tab 22, thereby make curve tab 22 weaken preferably the impact kinetic energy of bullet, and farthest changed the impact direction of bullet.
