Definitions

  • the invention relates to a composite material for Armor Piercing Incendiary (API) and Incendiary projectiles, and a corresponding manufacturing method.
  • API projectiles have been part of the state of the art for a long time and are described, for example, in US Pat. No. 1,380,773 A. They are used to hit the mark by light and to set fire to flammable objects. So when a projectile hits, it should emit a flash of light. Particularly well-known are four different systems:
  • FAP Frangible Armor Piercing
  • an ammunition that has a multi-part construction, but in particular does not consist solely of metal powder.
  • This metal powder titanium or zirconium
  • This metal powder is embedded in epoxy resin and thus forms a combustible part which emits a bright light upon impact (such as in US 5299501 A).
  • Pyrotechnic systems are widely used for larger calibers (military mid-caliber). They contain a pyrotechnic set, which is initiated upon impact and emits a bright light. These pyrotechnic charges usually consist of a proportion of magnesium or aluminum and a proportion of oxygen suppliers in solid form (see, for example, US 3,028,808 A).
  • Multi Purpose bullets are also among the pyrotechnic systems, but in addition to a glowing pyrotechnics, they also have a set of exploded. This achieves a combination of target mark, fire set, shrapnel production and penetration effect.
  • this type of projectile has the great disadvantage that the required multi-layer structure is additionally associated with relatively high production costs (US Pat. No. 5,648,870 A).
  • API projectiles in the small caliber area are usually built in three parts.
  • the shoe preferably consists of a rotating part of a brass alloy. This shoe is in contact with the barrel. Therefore, a high ductility is required here. The shoe must not damage the steel barrel.
  • a hard core is inserted in the center of a preferred designed projectile. This consists of a steel or tungsten alloy. The purpose of the hard core is to ensure penetration.
  • the incendiary share in these projectiles is provided by the titanium tip.
  • the titanium tip is usually made of solid material and often has a relatively complex construction, as it is at the top and still provide enough space for the long hard core. However, it is also conceivable to manufacture incendiary projectiles without a hard core.
  • the present invention therefore had the object of finding a material that is less expensive and to find a method that is more material-saving.
  • the starting material consists of a mud-like structure that can be easily processed into powder. This is also the reason why the powders (precursor material) of the respective materials are comparatively inexpensive. Therefore, according to the invention, it is particularly optimal to use a method in which the tips of the projectiles are made so that powder material can be used. This significantly reduces waste, although the contours can still be complex.
  • the matrix of the composite can be used to permanently bond the bullet and core sections. To keep the bullet as low as possible, the tip should be directly available in the previously defined and desired color without the need for additional dyeing.
  • a metal powder preferably titanium or magnesium powder is embedded in a polymer matrix.
  • the polymer composite material can be formed by transfer molding or other suitable molding techniques.
  • a thermoset or thermoplastic can be used as the matrix polymer.
  • the metal powder fulfills the function of the set of fire, the matrix serves as a carrier and at the same time as a mounting material for the other two parts (hard core and bullet shoe).
  • a connection between the main projectile and the polymer composite material is conceivable, but this only comes into consideration for the Incendiary variant.
  • the structure of a projectile according to the invention is shown in FIG. 1.
  • the polymer-metal composite preferably consists of at least 50% by volume of a metal powder.
  • the metal powder is preferably selected from the group consisting of titanium, magnesium, aluminum, zirconium or any mixtures thereof, preferably the metal powder is titanium or magnesium.
  • the polymer matrix preferably consists of a thermoplastic industrial plastic, for example polyether ketone (PEEK) or another industrial plastic. PEEK is particularly suitable for the application because of the wide temperature band in which the product can be used.
  • the tip of the projectile is sprayed directly onto the bullet shoe and the hard core.
  • bullet core and bullet shoe can be provided with a rough surface, notches or radial grooves.
  • the precursor piece (FIG. 2) consisting of a bullet shoe with the core located therein, can be inserted into the injection molding tool and encapsulated from the tip.
  • the pressing is no longer necessary with a press fit to obtain the precursor piece.
  • the placement of the bullet tip also falls away and the injection molding of the bullet tip an additional seal is obsolete.
  • a modular design may be considered.
  • the individually produced composite polymer projectile nose can be fastened with a snap closure, a bayonet closure or a press fastener on the precursor. This becomes a decentralized Production possible.
  • An embodiment with a missile configuration which can be modified shortly before use is thereby also possible. It is possible in a particularly noteworthy embodiment to use either a plastic tip without metal content or a tip with different mixtures. This allows a single projectile design to be used as an AP ammunition or API ammunition.
  • the operating principle for the flash of light can be explained as follows. Due to the short-term dynamic impact of the tip, the plastic reacts brittle-fracture-prone, so that the plastic-metal composite breaks up like a ceramic. The metal powder particles are released. Due to the impact friction, the particles are also warmed up and ignite z. The magnesium needs more energy until the auto-ignition temperature is reached, which is why a changed fire pattern is shown, but an ignition on impact is still possible. In metal powder mixtures, therefore, a desired effect can be achieved, for example, a flame coloring by addition of other elements is conceivable. In particular, the alkali and alkaline earth metals come into consideration, which often have a characteristic flame color. Particularly suitable are additives of potassium, sodium, barium, calcium, lithium, boron, strontium.
