Definitions

  • the invention relates to a projectile with a splinter-forming outer shell and one on the inside adjoining the outer shell plastic film, in which a Explosive charge is arranged.
  • the invention further relates to methods of manufacture of such a floor.
  • Such a projectile is known for example from DE-AS 1 812 462. It points the plastic film has a structured area with several circumferential sides evenly distributed and inward-facing roof-shaped indentations is provided, wherein the indentations of adjacent rows are arranged offset from one another are. At least the structured area of the plastic film is laterally connected a smooth area of the film with which the film is form-fitting on the inner wall fits the outer shell. As far as the applicant is aware, is used as material for the total, i.e. plastic film covering both areas an elastic propylene (propylene, which is provided with an elastic addition).
  • the invention has for its object in a projectile of the type mentioned ensure that it is safe even when using plastic-bound explosives no cracking of the explosives during the acceleration phase of the projectile comes. Methods for producing such a projectile are also to be disclosed become.
  • the invention is essentially based on the idea that a film is a plastic film to be used, which have at least two areas of different strength properties consists.
  • the plastic film consists of a deformation-resistant Material, which impresses the roof-shaped indentations during the acceleration phase of the projectile prevented by the explosive.
  • the plastic film consists of an elastic plastic material, so that the film in this area is elastic and form-fitting against the inner wall the outer shell is pressed.
  • the areas can be used to produce the plastic film for the projectile according to the invention made of rigid plastic material and elastic plastic material be produced separately by blow molding and then together welded, glued or melted together when blowing.
  • Polypropylene has again been found to be advantageous as the base material for the plastic film proved.
  • Appropriate additives on the one hand result in a very rigid deformation Material and on the other hand (e.g. by a rubber-elastic additive) a corresponding elastic material.
  • the side view is of an artillery weapon lockable explosive bullet before the introduction of an explosive charge and the closure of the front mouth hole with an impact igniter.
  • the floor is designated by 1, which comprises a splinter-forming outer shell 2 Steel covered. Inside the shell 2 is a plastic film 3, in which the explosives, not shown, is arranged.
  • the plastic film 3 has a central one with roof-shaped indentations 4 structured area 5.
  • This structured area 5 adjoins the front and on the rear side each with a positive fit on the inner wall 6 of the outer casing 2 adjacent smooth area 7, 8.
  • the structured area 5 of the plastic film 3 consists of a deformation-resistant Plastic material, e.g. made of polypropylene, possibly glass fiber reinforced, during the smooth areas 7, 8 of the plastic film 3 each made of an elastic plastic material, e.g. from a polypropylene with an elastic addition, consist.
  • a deformation-resistant Plastic material e.g. made of polypropylene, possibly glass fiber reinforced, during the smooth areas 7, 8 of the plastic film 3 each made of an elastic plastic material, e.g. from a polypropylene with an elastic addition, consist.
  • the plastic film 3 for the invention Floor 1 from separate sub-films corresponding to areas 5, 7, 8 assembled and in the areas designated 9, 10 with each other, e.g. with help by ultrasound, welded.
  • the invention is not based on the embodiment described above limited.
  • a material for the plastic film instead of polypropylene another base material can be used, in which by appropriate Additions the required strength requirements can be set.

Claims (5)

  1. Projectile comportant une enveloppe extérieure (2) du type à fragmentation et une feuille plastique (3) adjacente à l'enveloppe extérieure (2) du côté intérieur, dans laquelle est agencée une charge explosive, la feuille plastique (3) comportant une zone structurée (5), munie de creux (4) en forme de toit, et au moins une zone lisse (7, 8) aboutée à la zone structurée (5) et s'appuyant par conjugaison de forme sur la paroi intérieure (6) de l'enveloppe extérieure (2), la zone structurée (5) de la feuille plastique (3) étant formée par une matière plastique résistant à la déformation, caractérisé en ce que la zone lisse (7, 8) est formée par une matière plastique élastique.
  2. Projectile selon la revendication 1, caractérisé en ce que la matière plastique élastique est un polypropylène, auquel est ajouté un complément élastique.
  3. Projectile selon la revendication 1 ou 2, caractérisé en ce que la matière plastique résistant à la déformation est un polypropylène.
  4. Procédé de fabrication d'un projectile (1) selon l'une quelconque des revendications 1 à 3, caractérisé en ce que pour, la réalisation de la feuille plastique (3), la zone (5) en matière plastique résistant à la déformation et la zone (7, 8) en matière plastique élastique sont réalisées séparément et en ce que les feuilles partielles correspondant à ces zones (5, 7, 8) sont assemblées les unes aux autres par soudage, collage ou par thermofusion au cours du soufflage.
  5. Procédé de fabrication d'un projectile (1) selon l'une quelconque des revendications 1 à 3, caractérisé en ce que, pour la réalisation de la feuille plastique (3), on réalise tout d'abord, par extrusion-soufflage de corps creux à partir de matières conformément différentes et de même base, un tuyau flexible d'un seul tenant, auquel on confère ensuite son contour définitif dans un moule de soufflage.
