Description
technical fieldthe present invention relates to a kind of armour plate, relate in particular to a kind of steel plate that improves the bullet-proof car ballistic performance.
background technologybullet-proof car is a kind of special-purpose vehicle that new development is got up, bullet-proof car series is numerous, different uses has different specific requirements, shellproof is common basic demand, and the ballistic performance that how to improve bullet-proof car is the core research topic in this field, at present, improve the ballistic performance of bullet-proof car generally by two approach: the one, by increasing the thickness of bullet resistant material, can prevent bullet penetration bullet-proof car, but the thickness of raising bullet resistant material simply, will inevitably increase the quality of automobile, thereby reduced the dynamic property of automobile, bullet-proof car can not be sailed out of fast dangerous on-the-spot, increased the danger of occupant's life and property, the 2nd, the performance of raising bullet resistant material, but improve the intensity of bullet resistant material simultaneously, also increased the fragility of bullet resistant material, be unfavorable for that bullet resistant material absorbs the kinetic energy of bullet, and be also very difficult by the ballistic performance that the performance that improves bullet resistant material promotes bullet-proof car.
summary of the inventionthe drawback that the object of the present invention is to provide a kind of performance that not only overcomes to increase the thickness of bullet resistant material and improve bullet resistant material to bring, take to change the structure of bullet resistant material, reach the purpose that improves ballistic performance, reduce the input of manpower, financial resources, and simple in structure, be convenient to manufacture low cost of manufacture, effective armour plate.
The present invention is mainly the composite plate be composited by multilayer steel plates, and concrete technical scheme is as follows:
The present invention mainly includes lamina rara externa, nexine plate, sandwich plate, filler, dish spring and external piece, wherein lamina rara externa is plain plate, one side of this lamina rara externa is established nexine plate in parallel, this nexine plate is plain plate, establish the plate body that two axis all are parallel to the nexine plate between above-mentioned nexine plate and lamina rara externa, i.e. sandwich plate I and sandwich plate II, described sandwich plate I and sandwich plate II are all that cross section is corrugated steel plate, wherein the sandwich plate I is near the nexine plate, and the sandwich plate II is near lamina rara externa; Described nexine plate and sandwich plate I link together by upper and lower two external pieces between them, the upper/lower terminal between nexine plate and sandwich plate I is established respectively external piece, this external piece is bent plate, one end and the sandwich plate I of each external piece weld together, and the other end and nexine plate weld together; Above-mentioned lamina rara externa and sandwich plate II link together by upper and lower two the dish springs between them, the upper/lower terminal between lamina rara externa and sandwich plate II is established respectively the dish spring, an axial end and the lamina rara externa of each dish spring weld together, and axially the other end and sandwich plate II weld together; Between above-mentioned nexine plate and sandwich plate I, between sandwich plate I and sandwich plate II and establish respectively filler between sandwich plate II and lamina rara externa, this filler is the complex fiber material with bulletproof ability, for example: WB-212 type PEUD shellproof without latitude cloth (surface density: 150 ± 8g/ ㎡, thickness: 0.16mm) or FT-102 type aramid fiber UD shellproof without latitude cloth (surface density: 230～240g/ ㎡, thickness: 0.2 mm) or the TYZWB-211 type shellproof without latitude cloth (surface density: 305 ± 15g/ ㎡, thickness: 0.34 ± 0.02 mm).
Wherein preferred: the thickness of lamina rara externa is 1.8～2.2mm, preferred: the thickness of lamina rara externa is 2mm.
Wherein preferred: the thickness of nexine plate is 0.6～1.0mm, preferred: the thickness of nexine plate is 0.8mm.
Wherein preferred: the thickness of sandwich plate is 1.3～1.7mm, preferred: the thickness of sandwich plate is 1.5mm.
The present invention is adding man-hour, to stagger mutually in two summits of the chamfered transition with bevelled sandwich plate, like this, preventing from after bullet from running through lamina rara externa acting directly on this point, avoid puncturing this to the sandwich plate with inclined-plane, play good protective action, the inclined-plane of sandwich plate and horizontal plane have an angle, when bullet is vertically invaded sandwich plate, penetrativeness resolves into along the tangential force on inclined-plane with perpendicular to the normal force on inclined-plane, in addition, two exist friction with relative displacement between the sandwich plate on inclined-plane, decayed under effect together at them kinetic energy of bullet, bullet velocity is descended rapidly, weaken the penetrability of bullet, filled the complex fiber material with anti-resilience energy power between each layer of steel plate of the present invention, they also can play the effect of the kinetic energy of decay bullet, have reduced the speed of bullet, have weakened the penetrability of bullet.
The present invention compared with prior art has following advantage:
1, overcome to increase the thickness of bullet resistant material and improve the drawback that the performance of bullet resistant material is brought, taking to change the structure of bullet resistant material, reaching the purpose that improves ballistic performance;
2, reduce the input of manpower, financial resources, low cost of manufacture;
3, simple in structure, to be convenient to manufacture, bulletproof effect is good.
the accompanying drawing explanationfig. 1 is that master of the present invention looks the section simplified schematic diagram.
