Definitions

  • Ceramic has been used for many years in combination with other materials as ballistic protection of persons and objects.
  • the decisive advantage of a ceramic armor is a significant weight saving of the ceramic composite systems of more than 50% compared to conventional armor steels.
  • the properties of a ceramic material for ballistic or similar protection applications can be varied by the choice of the raw materials used, their composition and the process parameters during production (hardness, strength, toughness, density).
  • optimum protection, especially with multi-hit stress can only be achieved through a combination of materials with high hardness (front) and high toughness (behind).
  • the hard layer in the front area has the task to deform or break the projectile.
  • the underlying layer or layers serve to intercept the projectile or its debris and the splinters of the destroyed ceramic.
  • the invention has for its object to propose a component for ballistic protection applications, which ensures more effective protection over the prior art.
  • the invention has for its object to propose a method for its production.
  • the object is achieved by a component for ballistic protection applications with front and back, consisting of a multilayer Function composite or a functional composite of the front and back has a material gradients achieved in that therhythmskomposit introduced mechanical stress states.
  • the object is achieved by a method for producing a front and back component for ballistic protection applications, wherein two or more ceramic or non-ceramic materials are layered or in the form of a material gradient in the manufacturing process, such that the front side functionally has high hardness and compressive strength for erosion and reduction of the penetration depth of a projectile and the underlying layer towards the back to trap the remnants of the projectile and the material splitter was formed in that targeted mechanical stresses are induced in the layer structure.
  • the advantages achieved by the invention are that the first layer of material facing the stress (e.g., projectile) has high hardness and results in deformation, fragmentation and erosion of the impacting body.
  • the underlying material or materials have a higher toughness and thus hinder the crack propagation and thereby limit the damaged volume of the armor.
  • Shaping may be by uniaxial dry pressing or other conventional molding techniques (e.g., casting, tape casting, spraying, isostatic pressing, printing).
  • the various materials can be separated or successively added to the tool or the mold and simultaneously formed into a green body.
  • the production can also be carried out by two or more successive shaping processes.
  • All or individual layers of the composite may alternatively be prepared by joining molded articles or sheets of different materials by sintering, soldering or gluing.
  • the introduced stresses can be used during sintering or during joining processes to form curved contours of the finished molded bodies.
  • the resulting geometry contributes to the targeted impulse deflection.
  • FIGS. 1 to 3 are shown components with different layer structures.
  • the component consists of a first layer 1, a second layer 2 and a third layer 3.
  • First layer 1 and third layer 3 consist of different ceramic materials.
  • the second layer 2 consists of a mixture of the materials of the first layer 1 and the third layer 3.
  • the first Layer 1 is functionally the particularly hard layer that destroys the projectile and the following layers catch the splinters.
  • the component according to Fig. 2 has in addition to the structure according to Fig. 1 a connected via a joining zone 4 porous layer 5, which is filled with a plastic.
  • the stresses are introduced in such a way that a curved geometry of the layer structure is generated. The geometry designed in this way contributes to targeted impulse deflection.
