US12536347 - Helical patterning on a curved surface for additive manufacturing of a fragmentation device

Methods of creating geometry for a fragmentation device are presented. The geometry may be generated using computer-aided design tools. An inner body with a curved surface may be generated. An intersection line may be generated on the curved surface by tracing a helical path. A fragment comprising a fragment surface tangent to the curved surface may be generated and aligned with the intersection line. A pattern of fragments may then be generated based on the fragment, the intersection line, and the curved surface. The geometry of the fragmentation device may be stored for manufacture of the fragmentation device by additive manufacturing.

US12379195 - Method for manufacturing an ammunition cartridge and ammunition cartridge

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.

US12339106 - Fiber reinforced bullet and method of manufacture

Bullet constructed from FRP, preferably basalt. The method includes the step of forming pultruded basalt strands positioned co-axially before milling to form a conventional bullet shape. The process uses a 10 mm FRP rod held by a revolving collet that is interfaced with an upper diamond OD grinder and a lower diamond profile wheel. Gravity allows the rod to rest on a Teflon coated cut off wheel. The upper grinder draws the rod to an exact outer dimension and the lower grinder cuts the bullet to a perfect dimension. Linear slides move the cut off wheel and grinders in for the cutting process and out to allow the finished bullet to pass.
