Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention will be further described

[0017] A lightweight composite cartridge suitable for low to medium chamber pressures such as figure 1 As shown, it includes a base layer 1, a reinforcement layer 2 and a surface coating 3. The base layer 1 uses epoxy resin as the base material and is formed by gas mold casting. The uniform infiltration volume fraction of the epoxy resin is 2%. SiO 2 Nanoparticles and a small amount of curing agent, the mouth of the base layer 1 is provided with protrusions 4, which cooperate with the grooves on the bullet to improve the pull-out force when the bullet is fired, and the reinforcing layer 2 is carbon fiber, such as figure 2 As shown, the carbon fiber is at 60-63 degrees (60 O -63 O ) is wound on the outside of the base layer 1, the surface coating 3 is sprayed on the outside of the reinforcing layer 2, and the surface coating 3 is polytetrafluoroethylene; the thickness of...

Abstract

The invention provides a light composite material cartridge case suitable for medium and low chamber pressures specific to problems in the conventional cartridge case. The light composite material cartridge case comprises a substrate layer, a reinforcing layer and a surface coating, wherein the substrate layer is prepared by casting epoxy resin serving as a substrate material with a gas mold; 2 percent SiO2 nanoparticles and a small amount of curing agent uniformly permeate into the substrate layer; the reinforcing layer is made of carbon fibers; the carbon fibers are wound outside the substrate layer at the winding angle 60-63 degrees; the surface coating is made from polytetrafluoroethylene, and is coated outside the reinforcing layer. The cartridge case has the characteristics of high strength, light weight, stable chemical stability and the like, the working efficiency and high-radio-frequency firing rate are increased, and the consumption of metal resources is lowered.

Description

technical field [0001] The invention relates to a cartridge structure, in particular to a lightweight composite cartridge suitable for medium and low chamber pressures. Background technique [0002] The cartridge is the basic support of the bullet, and its main functions include: loading gunpowder inside; fixing and supporting the bullet at the mouth of the barrel; the outer shape plays a role in positioning the bullet; the cartridge can also protect the chamber and reduce the impact of gunpowder gas on the chamber. Ablation, while ensuring gas-holding, to prevent gunpowder gas from ejecting from the rear of the barrel. [0003] At present, most of the cartridge materials of small and medium caliber conventional weapon ammunition are metal materials such as copper and steel. Metal cartridges have the characteristics of high reliability, easy storage and high safety; however, with the development of high-speed weapons Due to the demand for larger ammunition during developmen...
