Description
Technical field
Bulletproof ceramic sheet equipment technical field is the utility model is related to, more particularly to a kind of heat safe shellproof pottery of carbonization
Tile.
Background technology
The bullet-proof mechanism of ceramics and metal is very different, and metal is due to be plastically deformed and absorb the kinetic energy of projectile,
And ceramics are due to its rupture and absorb the kinetic energy of projectile.In general, ceramic armour system is by layered ceramic or Ceramic-to-Metal
Compound simultaneously forms (glass fibre also can) covered with the nylon cloth layer that high-tensile organic fiber combines.Bulletproof ceramic will
The performance asked is more, such as:Density and the porosity, hardness, fracture toughness, Young's modulus, the velocity of sound, mechanical strength etc., Ren Heyi
A performance cannot all have direct and conclusive relation with overall ballistic performance, thus fracture mechanism is sufficiently complex, and crackle is formed
Be as caused by many factors, and occur time it is very of short duration.The porosity of bulletproof ceramic should be as far as possible low, to improve hardness
And Young's modulus, to Al2O3For porcelain, its porosity should be close to zero, and water absorption rate is no more than 0.02%.The hardness of ceramics will
Ask very high, the hardness of flight bullet is should be higher than that, to Al2O3For ceramics, hardness Hv should be more than 1220~1250.Sound is in ceramics
The speed of middle propagation, represents the ability of consumed energy on ceramic shock surface, it is desirable to have the high velocity of sound, the high velocity of sound also secondary indication
Ceramics have good densification and low sealed porosity.However, these material manufacturing methods use expensive hot pressing, it is not easy
Industrialization.But hot pressing can improve the mechanical performance of bulletproof ceramic, this point is also apparent.Ceramic matrix composite is prevented with high
Elastic energy, this is because there is high mechanical performance, is particularly fracture toughness.After ballistic impact, compared with layered ceramic, pottery
Porcelain base complex has preferable integrality.
The ballistic resistant sheet that China uses at present is mostly metal ballistic resistant sheet, but metal ballistic resistant sheet is since its density is larger,
Quality is larger under same volume, has seriously affected the flexibility of wearing ballistic resistant sheet soldier's movement, while when by bullet hits
Easily by metal melt, soldier is caused to be burnt.
