Description
Technical field
Patent of the present invention relates to a kind of passive type anti-bullet of pottery unit, especially relates to a kind of knockdown anti-bullet unit, can be applicable to the protection of armored vehicle, naval vessels and helicopter.
Background information
From the historical development of armour material, from traditional metal material as steel, aluminium, advanced ceramic material, composite till now, armour material is always towards the efficient future development of light weight.And the bulletproof ceramic, the bulletproof composite material that occur subsequently, with its lighter quality and the excellent ratio of performance to price, have replaced metal armor in popular field gradually.In numerous bullet-resistant ceramic materials, that be most widely used is Al

3ceramic material has improved approximately 40%, and material range of application is wide, is particularly suitable for armor facing field.Although reduced ceramic density, improved specific strength, the preparation condition of this material and sintering process are complicated, are unsuitable for promoting on a large scale.
Summary of the invention
For addressing the above problem, the present invention discloses a kind of passive type anti-bullet of pottery unit, it is characterized in that external structure is comprised of open tubular column aluminium oxide ceramics, and internal structure is filled by boron carbide ceramics stem stem, is binding agent between internal structure external structure.The aluminium oxide ceramics 10 of external structure adopts the open tubular column shape of a head face hump, and outer surface cylindricality diameter is 12～24mm, and the non-bossing height of cylinder is 15～28mm, and protruding cambered surface Partial Height is 3～6mm, and hollow ceramic post thickness is 3～6mm.The aluminium oxide ceramics of external structure adds wild phase, and the second-phase adding is ceramic particle, ceramic whisker carborundum, zirconia.The boron carbide ceramics stem stem 30 of internal structure is filled in open tubular column inner space completely, and contour structures is consistent with aluminium oxide ceramics post inner surface structure.Adhesive thickness is 1～30um.
The present invention is intended to the anti-bullet ceramic unit by being comprised of outside corundum ceramic and inner boron carbide ceramics, reduces the density of former aluminium oxide ceramics post, and boron carbide ceramics ballistic performance is better than aluminium oxide simultaneously, thereby improves the bulletproof performance of ceramic unit.And, in aluminium oxide ceramics and boron carbide ceramics, add second-phase composition, can greatly improve the toughness of system.Although reduced the compressive strength of system, resultant effect is that the anti-resilience energy power of system has been improved.Can be used as the protection ceramic unit of 7.62mm and above middle-size and small-size bore armor-piercing incendiary thereof.
The invention has the advantages that: (1) cambered surface projection ceramics pole is easy to meet bullet and makes bullet driftage; (2) combination of hollow alumina ceramics pole and boron carbide ceramics stem stem reduces density and the weight of system; (3) add the toughness that second-phase wild phase is summarized system greatly.
