preparation example Construction

[0050] The present invention also provides a preparation method of the above-mentioned composite material long-rod projectile with high penetration ability, the preparation method comprising:

[0051] 1) arranging the tungsten fiber on the outside of the secondary diameter tungsten rod, and filling the zirconium-based metallic glass between the tungsten fiber and the secondary diameter tungsten rod;

[0052] 2) The system is successively vacuumized, heated, pressurized, pressure-maintained, heat-preserved, and cooled.

[0053] In the above preparation method, the technology of "pressure-penetration-rapid solidification" can make the combination between tungsten fiber, zirconium-based metallic glass and sub-diameter tungsten rod more stable, thereby improving the penetration ability of long rod projectile .

[0054] Wherein, in the above preparation method, the vacuum degree of the system after the vacuuming can be in a wide range, but in order to further improve the penetrati...

Embodiment 1

[0061] according to Figure 1-2 As shown, 7 circles of the first tungsten fiber layer 1 are sequentially sleeved on the outside of the first diameter tungsten rod 3 from the inside to the outside, and then the zirconium-based metallic glass is filled in the first tungsten fiber layer 1 and the first diameter tungsten rod. 3 and between adjacent first tungsten fiber layers 1 to form a first zirconium-based metallic glass layer 2 .

[0062] The first diameter tungsten rod 3, the zirconium-based metallic glass and the first tungsten fiber layer 1 are all fixed in the mold, the mold is put into the crucible and sealed, and then the crucible is evacuated to 1×10 -3 MPa, then heat up from 293K to 1123K, then pressurize to 0.6Mpa, then keep the pressure for 10min, and finally cool with the furnace to make uniform long-rod bombs.

[0063] Wherein, the diameter of the tungsten fiber is 300um, and along the direction from the center to the outer edge of the first diameter tungsten rod ...

Embodiment 2

[0065] Carry out according to the method of embodiment 1, the only difference is:

[0066] The first diameter tungsten rod 3, the zirconium-based metallic glass and the first tungsten fiber layer 1 are all fixed in the mold, the mold is put into the crucible and sealed, and then the crucible is evacuated to 1×10 -4 MPa, then heat up from 293K to 1120K, then pressurize to 0.5Mpa, then keep the pressure for 15min, and finally cool with the furnace to make uniform long-rod bombs.

Abstract

The invention discloses a composite material long-rod projectile with high penetration ability and a preparation method thereof. The composite material long-rod projectile comprises a sub-diameter tungsten rod, a zirconium-based metal glass layer and a multi-circle tungsten fiber layer; the zirconium-based long-rod projectile The metal glass layer covers the outside of the secondary diameter tungsten rod, the multi-circle tungsten fiber layer is arranged in the zirconium-based metal glass layer, and the multi-circle tungsten fiber layer is sequentially sleeved inside and outside the secondary diameter. Outside the diameter tungsten rod, the outer edge of the second diameter tungsten rod is in contact with the tungsten fiber layer of the innermost circle; each circle of the tungsten fiber layer includes a plurality of tungsten fibers that are in contact with each other and connected end to end. The composite long rod bullet solves the technical problems of the bending deformation of tungsten fibers and the softening of the metal glass matrix existing in the penetration process of the existing tungsten fiber metal glass matrix composite materials.

Description

technical field [0001] The present invention relates to a long-rod bullet, in particular, to a composite material long-rod bullet with high penetration ability and a preparation method thereof. Background technique [0002] As a typical kinetic energy weapon, armor-piercing projectile has developed rapidly and become an effective anti-tank projectile due to its advantages of high power, good anti-bounce performance, ideal after-effect effect and effective destruction of composite armor. However, with the development of protective armor and the energy level limitation of the current launch system, the damage ability of armor-piercing projectiles is gradually declining. [0003] In order to improve the penetration ability as much as possible under the limited launch ability, tungsten or depleted uranium are mostly used as materials for armor-piercing projectiles in the military field. Compared with the "mushroom head" of tungsten alloy, depleted uranium will have a self-sharp...
