Definitions

  • the invention relates to an insert for shaped charges or penetrators or balancing bodies for projectiles made of a high-density material.
  • Inserts for shaped charges are made of tough metals of relatively high density, such as copper, iron, tantalum.
  • the quality of the beam or projectile depends on the geometrical accuracy and the homogeneity of the explosives and the insert material.
  • the material properties such as strength, crystalline structure, electrical conductivity, change in every direction, such as height, radius and circumference. The strength values differ from point to point. Accordingly, undesirably strong disturbances in the insert geometry are obtained even under otherwise ideal conditions.
  • the inserts consist of a composite material formed from tungsten and copper.
  • the individual tungsten grains are brought together to form a homogeneous structure by a binder.
  • the grain size of the tungsten is between 2 to 90 ⁇ m.
  • the object of the invention is to propose an insert for shaped charges or a balancing body which has an improved penetration through improved homogeneity.
  • the insert or the balancing body according to the invention has a homogeneous structure and an isotropic material behavior with any load and deformation. For the shaped charge, this results in a significant increase in the performance of the particle beam in its final ballistic form, either as a beam, as a splinter or as a projectile. Due to the strong mechanical deformation, there is a firm material structure in the insert or the balancing body due to the adhesion. This applies in particular to a material association in which the grains stick together without a binder by means of adhesion.
  • the grains of the material according to the invention are in a matrix material, such as copper, the properties of the thin matrix layer are largely negligible, so that such an insert or balancing body achieves almost the same effects as when using the material according to the invention without a matrix material.
  • the stress-strength distribution is symmetrical in all levels and the effects of the insert or the balancing body are reproducible.
  • the invention is suitable for rotationally symmetrical shaped charges as well as for flat shaped charges, namely cutting loads and their splinter-forming varieties.
  • Projectiles from projectile-forming inlays are symmetrical and therefore fly straight ahead, so misses are avoided.
  • the sintering method known per se is also suitable for less efficient deposits or balancing bodies.
