Description
Technical field
The present invention relates to a kind of flak jackets, especially a kind of aeroge flak jackets.
Background technique
Flak jackets is called bulletproof jacket, keeps away ballistic vest, and bullet-proof vest keeps away bullet clothes, individual soldier's watch box harness etc., for protecting bullet
The injury of head or elastic slice to human body.Flak jackets is mainly made of clothing set and burster course two parts.Clothing covers common chemical fibre fabric production.
Burster course is with metal (special steel, aluminium alloy, titanium alloy), potsherd (corundum, boron carbide, silicon carbide, aluminium oxide), glass
Steel, nylon (PA), Kevlar (KEVLAR), ultra high molecular weight polyethylene fiber (DOYENTRONTEX Fiber), liquid-state protective
The materials such as material constitute single or compound safeguard structure.Burster course can absorb the kinetic energy of bullet or elastic slice, to low speed bullet or
Elastic slice has apparent protection effect, can reduce the injury to human body chest, abdomen when controlling certain recess.Flak jackets packet
Include infantry's flak jackets, aircrew's flak jackets and artilleryman's flak jackets etc..Bullet-proof vest can be also divided into according to appearance, full protection is shellproof
Clothing, the types such as Ms's flak jackets.
In terms of the ballistic performance of flak jackets is mainly reflected in following two:
(1) ballistic resistant sheet: the high speed fragments that the explosions such as various explosives such as bomb, land mine, shell and grenade generate are war
One of chief threat on field.According to investigations, the threat size order that the soldier in a battlefield is faced is: elastic slice, bullet, quick-fried
Fried shock wave and heat.So extremely to emphasize the function of ballistic resistant sheet.
(2) anti-non-through damage: bullet can generate great impact force after hitting the mark, this impact force action in
Human body injury produced is often fatal.This injury does not show penetrability, but will cause internal injury, and severe one jeopardizes life
Life.So preventing non-through damage is also to embody and examine an importance of flak jackets ballistic performance.
Aeroge is that have porous, spongelike structure solid, wherein about 95% volume is air, is had ultralow close
Degree, super large hole, super large internal surface area, ultralow thermal conductivity, the ultralow velocity of sound and excellent thermal stability and mechanical performance, anti-
Bullet field is also widely applied.The patent document of CN1981925B is by surfactant-modified silicon dioxide gel and two
Titanium oxide sol mixing, is made titania/silica aeroge, but the intensity of the aeroge and flexibility are very poor, and
Expensive starting materials, higher cost.The patent document of CN 103203206B discloses a kind of Cellulose/titanium dioxide/silica gas
Gel can be applied to flak jackets, and as existing all aeroge flak jackets, in the presence of burster course
Ballistic performance it is bad.
There is also some flak jackets based on armour at present, such as publication No. is the patent document of 103234389 A of CN
Disclose a kind of elastic body armor, elastic ballistic structure includes armour and elastic fabric, muti-piece armour it is arranged in parallel by
Elastic fabric package, multilayer elastic ballistic structure are staggered front to back arrangement.However this flak jackets is too simple and weight is big, it is such hard
Board-like flak jackets effectively cannot can be carried out buffering to sub- springing when by bullet impact, thus the indirect wound caused by human body
Evil can be larger.If directly by shellproof plate (or lath) and aerogel layer simple composite, although its ballistic performance is improved,
But it is far from satisfying for the ballistic requirements of armored vehicle flak jackets.
It can be seen that how by shellproof plate improved in conjunction with aeroge flak jackets ballistic performance become it is shellproof now
The problem of collar domain urgent need to resolve.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of aeroge flak jackets, use unique texture will
Aeroge is combined together with foam metal plate, and ballistic performance is effectively improved on the basis of with certain compliance, and
Overall quality is lighter.
The technical solution adopted by the present invention to solve the technical problems is: a kind of aeroge flak jackets, by from outside to inside according to
The ballistic fiber layer of secondary setting, the first armour layer, the first aerogel layer, the second armour layer, the second aerogel layer composition, respectively
Interlayer passes through adhesive bond together；The first armour layer and the second armour layer by several pieces of shellproof piece of splits and
At shellproof piece of the first armour layer is open cell foam metal block, and shellproof piece of the second armour layer is closed-cell foam metal block；
The porosity of second aerogel layer less than the first aerogel layer porosity, first aerogel layer with a thickness of 3~
The thickness of 5mm, the second aerogel layer are greater than 8mm.
Embodiment as a further preference, described shellproof piece is square, thickness be greater than 2mm, side length be 0.8~
1cm。
The aperture of embodiment as a further preference, the open cell foam metal block and closed-cell foam metal block is small
In 0.1mm, porosity is 40~50%.
Embodiment as a further preference, described several pieces shellproof piece is wrapped up with elastic fabric and being connected.
Embodiment as a further preference, the aeroge are silica aerogel.
Embodiment as a further preference, the ballistic fiber are aramid fiber.
Embodiment as a further preference, the adhesive are epoxyn.
The positive effect of the present invention: ballistic fiber layer of the invention is initial buffer layer, is carried out to the bullet of injection preliminary
Kinetic energy decaying, while the design of the aerogel layer of its internal layer is so that ballistic fiber layer has sufficient deformation space, its by by
The direction of motion that bullet can also be changed while gradually penetrating to a certain extent, the bullet contact first for penetrating this ballistic fiber layer are anti-
Diving board layer, bullet are directly beaten on certain shellproof piece, and the aperture hole and macroporous first aerogel layer in this shellproof piece are again
For its deformation provide adequate space (if between bullet has got to adjacent shellproof piece of gap within the scope of minimum probability, then two
Shellproof piece of side can be deformed extrusion friction consumption bullet energy to bullet and change bullet direction), what is gradually punctured
It can integrally be pressed in the first aerogel layer simultaneously, this process can consume big energy, and further change the bullet direction of motion,
Bullet can directly contact the second armour layer, the first armour layer and second before not puncturing the first armour layer completely simultaneously
Shellproof piece of armour layer deforms in the second gel layer together, and works with the second gel layer one of fine pore sharply to decline
Subtract bullet travel speed, reaches shellproof purpose.The present invention designs to reach good ballistic performance using unique structure, wherein
Foam metal is utilized, it is well known that common foam metal has no bulletproof function, but we have found under study for action, will steep
Foam metal block can greatly promote ballistic performance when aeroge is used alone after combining in this way in conjunction with aeroge, this is obtained
It is combined beneficial to the dominant rigidity (intensity is big) of metallic foam block with dominant flexible (intensity is relatively small) of aeroge and foam
The recessiveness flexible (numerous small spaces offer deformation spaces) of metal block is combined with the recessiveness rigidity (resistance to pressure is strong) of aeroge,
Compared with existing aeroge flak jackets, the ballistic performance of this product is more preferably, it might even be possible to as armored vehicle flak jackets.
