Abstract
The invention relates to a double-layer corrugated ceramic composite structure armor and a preparation method thereof. Upper and lower parts of corrugated metal which are arranged in parallel or in a staggered way are respectively and fixedly arranged among three metal panels in a welding way to form metal structure sandwich plates, a triple prism-shaped ceramic core material is placed in a triple prism-shaped groove of a corrugated core body, and a liquid resin material is filled in a pore of the metal structure sandwich plate in which the triple prism-shaped ceramic core material is inserted. The structure of the light composite material structure armor is favorable for integrally playing roles of reducing the impact of a projectile and deflecting the projectile by the ceramic core material, the performances that the ceramic core material has high hardness and high strength, and effectively resists the impact of the missile projectile can be better played, and the defect that a single-layer composite structure armor is easily punctured by the missile projectile to lose a protective effect is overcome; and the double-layer structure composite material armor still has the lightweight characteristic, so that the defect that the maneuverability of a vehicle is affected by large weight is overcome.
Description
Technical field
The invention belongs to armoring production technical field, relate to structure armor and preparation method thereof, be specifically related to a kind of double-deck ripple ceramic composite construction plate armour and preparation method thereof.
Background technology
Because ceramic material has wear-resisting, heat-resisting, resistance to compression, the characteristics of high rigidity and stable chemical performance, a large amount of ceramic materials that use are in order to resist the impact of various external bullets in the present composite structure plate armour, dual mode is specifically arranged in application: a kind of is the positive layer that adopts ceramic wafer more than four layers or the direct overlapping placement of ceramic block to be used as structure armor, the impact that such structure armor can effectively be resisted various external bullets in the early stage plays a protective role, but directly that ceramic material is cracked easily at the various external bullet impacts of resistance as the positive layer of structure armor, and local action is obvious during whole plate pottery penertration resistance, can not give full play to armoring whole capability of resistance to penetration, therefore just can't effectively resist the especially impact of fly bomb of external bullet in this later stage, add that ceramic wafer more than four layers or ceramic block cause quality too heavy and affect the mobility of vehicle; Another kind is to be that skeleton, triangular prism shape ceramic material are that the individual layer composite structure that consists of of core and the gap potting resin material between the two is armoring by the metal structure sandwich plate; such structure armor its whole capability of resistance to penetration when resisting common bullet impact is strong; and quality gently can not affect the vehicle mobility energy; but the impact of bullet of resisting fly bomb is but very not enough; particularly be accompanied by a large amount of utilizations of individual soldier's anti-tank missiles weapon, such composite construction plate armour is very easily to be punctured by the fly bomb bullet and lose protective effect.
Summary of the invention
The deficiency that exists in order to overcome above-mentioned prior art; the object of the present invention is to provide a kind of globality that is conducive to bring into play the impact that ceramic core corrodes bullet; the effect of deflection bullet; and more can give play to ceramic core high rigidity; the performance of the bullet impact of high strength and effective anti-fly bomb; remedied that individual layer composite construction plate armour is very easily punctured by the fly bomb bullet and the defective of losing protective effect; and double-deck this composite structure plate armour has still kept the characteristics of lightweight, can't cause quality too heavy and affect the double-deck ripple ceramic composite construction plate armour and preparation method thereof of the mobility defective of vehicle.
For achieving the above object, preparation method of the present invention is as follows:
1) sheet metal after the annealing in process is carried out smooth after, bending acquisition angle is the ripple core body of θ again, then order arranges three metal deckings from top to bottom, and between adjacent two metal deckings the ripple core body is set, per two adjacent metal deckings are fixed together with the top of ripple core body and bottom respectively consists of the double-layer metal structure sandwich plate;
2) insert respectively the corresponding with it pottery of falling triangular prism shape core and regular triangular prism shape pottery core in all grooves of falling the triangular prism of double-layer metal structure sandwich plate and in the regular triangular prism groove;
3) filling liquid resin material in the slit between double-layer metal structure sandwich plate and regular triangular prism shape pottery core and the slit between metal structure sandwich plate and the pottery of falling the triangular prism shape core, then the metal structure sandwich plate of having filled liquid resin material is encapsulated, curing resin material obtains the double-layer composite material structure armor behind the curing molding.
Described step 1) detailed process is as follows:
Adopt planisher smooth sheet metal after the annealing in process, adopting hydraulic press mold pressing or forming mill bending to obtain angle is the ripple core body of θ again, subsequently to the oil removing that eliminates rust of two ripple core bodys and three metal deckings, and oven dry, and adopt welding manner will per two adjacent metal deckings respectively with the top of ripple core body and the bottom formation double-layer metal structure sandwich plate that is fixed together.
Described up and down two corrugated metal core bodys are parallel or be staggeredly placed.
It is carbon steel steel plate, corrosion resistant plate, aluminium sheet, titanium plate or the armour plate of 0.5mm～5mm that described sheet metal adopts thickness.
The thickness of slab of described metal decking is 1mm～10mm.
The angle θ of described ripple core body is 15 °～85 °.
The described pottery of falling triangular prism shape core and regular triangular prism shape pottery core use Al
2O
