Abstract
The present invention pertains to the field of the arms industry and metallurgy, and also to the fields of materials engineering and chemical engineering. More specifically, the present invention refers to a novel ammunition cartridge comprising reinforced polymer and the manufacturing process thereof. The ammunition cartridge serves for receiving the gunpowder so that explosion can occur inside the weapon barrel. The technology proposed reduces the quantity of components to be pre-manufactured and assembly processes on the product, producing a full cartridge, directly upon injecting the thermoplastic, and can also use bi-component injection. With this, the portion of the collar ring can be made entirely of fiber-reinforced polymer material, which reduces the weight of the item and is beneficial for the useful life of the weapon in the bolt region.
