Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below to specific reality of the invention
The mode of applying is described in detail.In the following description, numerous specific details are set forth in order to facilitate a full understanding of the present invention.But
The invention can be embodied in many other ways as described herein, and those skilled in the art can be without prejudice to this hair
Similar improvement is done in the case where bright intension, therefore the present invention is not limited to the specific embodiments disclosed below.
A kind of embodiment of novel ballistic material of the invention, as depicted in figs. 1 and 2, by fibrage nitride layer 3, shearing
Thickening liquid layer 2, aerogel material layer 1 and protective case 4 are constituted, and there are three cavity, the fibrous braids for the tool of protective case 4
Layer 3, shear thickening liquid layer 2, aerogel material layer 1 are sequentially filled in three cavitys of protective case 4.
In this way, using specific weaving manner (such as polyaxial laying system, the laminated laminated cloth of one-way tape), obtained fibre
When tieing up fabric experience bullet, is extracted using fiber from fabric and the behaviors such as fiber tearing reduces bullet velocity, bullet is stopped to run through,
But the shellproof grade of the flak jackets for being single use fabric is low, and fabric is thick;
Shear thickening liquid is that a kind of non-newtonian fluid is cut in the case where low strain dynamic rate (when such as wearer does proper motion)
Cutting thickening liquid has soft mobility, and in the case where high strain-rate (when such as by ballisticimpact), shear thickening liquid
The quick retrogradation of meeting becomes hard, and is not affected by temperature;
Increase by one layer of shear thickening liquid layer behind fibrage nitride layer, fiber when meeting with bullet can be improved and pulled out from braided fabric
Out or energy needed for fiber tearing, projectile impact power dissipation region is widened, is effectively transferred to the impact force that bullet generates
Entire shear thickening liquid layer, and shear thickening liquid layer can continue to stop the bullet or son across fibrage nitride layer
The protrusion that bullet generates;
Aeroge is a kind of solid inorganic material with three-dimensional network skeleton structure and nanoscale hole hole, has high hole
Rate and specific surface area, extremely low density and solid content, chemical inertness, noninflammability show excellent lightweight, insulation, fire prevention, prevent
The characteristics such as quick-fried, damping energy-absorbing, bullet velocity can be effectively reduced, and (bullet has to pass through countless hole walls, energy when entering aeroge
Rapid decay), absorb the impact force and shock wave (spread speed of the shock wave in the nanoscale hole hole of aeroge that bullet generates
Very slow, spread speed of the sound wave in aeroge is about 110m/s), reducing the weight of bullet resistant material, (density of aeroge is
100kg/m3), the heat that barrier bullet generates (thermal coefficient of aeroge is 0.013W/mK);
Therefore, aeroge has with fibrage nitride layer, shear thickening liquid layer cooperates with anti-bullet effect, if bullet is through shearing
Thickening liquid layer, aeroge can protrusion caused by secondary blocking bullet or bullet, bullet or while protruding out into aeroge be necessary
Across countless hole walls, energy rapid decay avoids shock wave or the raised sense of discomfort caused by human body, shear thickening is effectively reduced
The thickness of liquid level and fibrage nitride layer, and aeroge can be blocked with efficient absorption bullet and the shock wave that is formed, keeps away
Exempt from that human body secondary injury is caused (if the shock wave that bullet generates effectively is not dispersed and absorbed, tissue to be easy to cause to frustrate
Wound and fracture, seriously affect the mobility of army and police), while aeroge can mitigate the weight of flak jackets significantly, assign flak jackets
The characteristic of heat-insulation and heat-preservation.
In the present embodiment, the fiber is aramid fiber, in carbon fiber, ultra high molecular weight polyethylene fiber, metallic fiber
One or more, preferably aramid fiber, carbon fiber, ultra high molecular weight polyethylene fiber.
In this way, aramid fiber density is low, intensity is high, good toughness, high temperature resistant, easy to process and molding, intensity is same
5 times of quality steel;
It is 20 times of steel that carbon fiber, which has characteristics, the intensity such as intensity is big, modulus is high, density is low, linear expansion coefficient is small,;
Ultra high molecular weight polyethylene fiber has high specific strength, high ratio modulus, and specific strength is more than ten times of same section steel wire, than
Modulus is only second to carbon fiber.
In the present embodiment, the weaving manner of the fibrous braid is one of tatting, knitting, non-woven or a variety of.
In this way, carrying out fibrous braid that different weaving manners obtains to identical fiber has different density, no
Flexibility together, different bulletproof performances select suitable weaving manner according to shellproof grade and required taking.
