Definitions
- the invention relates to a hollow or flat charge lining or projectile charge assignment.
- Such explosive charges which essentially have a mostly conical cavity with a more or less large opening angle on their side directly facing the target, are known per se in numerous embodiments.
- DE-OS 29 13 103 discloses a flat cone charge with a cavity which is provided with a metal insert which consists of an alloy which has such a high tantalum content that a density is achieved which is greater than that of the copper. Tungsten is also proposed for this alloy, as well as various other alloy metals. It has now been shown, however, that all of these copper alloys to date have a relatively insufficient homogeneity due to the widely differing properties of the metals used in terms of density and structure, which reduce the performance of the explosive charge.
- DE-PS 27 24 036 proposes to produce an insert from a copper bismuth alloy in the pressing process. The above also applies to this proposal, too there is insufficient homogeneity here.
- the present invention has for its object to provide a lining or covering for explosives of the type mentioned, which has an improved homogeneity and thus an improved penetration.
- the cutting performance and depth of cut of a shaped charge is a first approximation of the sum of the length of the spines at the bottom of the crater multiplied by the root of the ratio of the lining material density to the target material:
- the invention proposes that the lining or covering be made from a composite material formed from tungsten and copper put.
- the individual tungsten grains with a binder such. B. nickel or palladium combined with the copper to form a homogeneous structure.
- the good elasticity of the copper is combined with the heavy particles of tungsten on the one hand to form a spike of high density and thus an optimal composite material is obtained for this purpose.
- the proportion of tungsten is said to be between 50 and 95% and is to be produced in the desired form as a homogeneous composite material by pressing, sintering and post-pressing with the copper. It has been shown that a tungsten content of 60 to 80% results in an optimal material for many possible uses.
- the tungsten particles are embedded in the copper as a matrix.
- Another possibility for producing the composite material provides for tungsten and copper powder to be hot-isostatically pressed together with the binder, for example nickel or palladium, the temperature during the operation being above the melting point of the copper.
- the binder for example nickel or palladium
- Another method provides for mechanical pressing of pure tungsten material with suitable binders and subsequent sintering and then, in the second step, the infiltration of the copper material portion, the pressing process also producing the desired funnel or lining shape. This not only saves material but also processing time. It is also proposed to select the grain size of the tungsten for the production of the composite material in the range from 2 to 90 ⁇ . Grain sizes in the range from 30 to 60 ⁇ have proven particularly advantageous.
