preparation example Construction

[0032] The present invention also proposes a method for preparing the empennage-stabilized shell-piercing projectile carrier as described above, comprising:

[0033] S1: According to the force analysis results of the spring holder, divide the spring holder into tooth buds and outer casings, and design the layer angle and layer thickness of the tooth buds;

[0034] According to the limitations of the process conditions, the tooth bud is divided into several sections along its axial direction and prepared separately;

[0035] S2: Choose carbon fiber prepreg as the layering material of the tooth bud, prepare the carbon fiber prepreg according to the layer thickness of the tooth bud, and prepare the carbon fiber prepreg (resin mass content is 25-35%) according to the layering angle of the tooth bud Lay layers on a flat mold according to the thickness of the layer, heat and pressurize, solidify, demould, and process to obtain a tooth bud shape block;

[0036] S3: Repeat step S2 to...

Embodiment 1

[0062] The present invention provides a kind of empennage stabilizing armor-piercing projectile receptacle, and described receptacle is made up of 3 pieces of 120 ° carbon fiber composite clasp by hoop combination, and described clasp comprises tooth bud 2 and outer casing 1 (such as figure 1 and 2 As shown), the outer shell 1 is covered on the outer surface of the tooth bud 2, and the tooth bud 2 is processed and combined by several carbon fiber molded plates with different layup angles and layup thicknesses; the outer shell 1 is made of chopped carbon fiber prepreg yarn Molded.

[0063] The present invention also provides a method for preparing the above-mentioned tail-stabilized shell-piercing armor-piercing projectile carrier, comprising:

Abstract

The invention discloses an empennage stable shelling armor-piercing projectile support and a preparation method thereof. The projectile support is formed by combining three 120-degree carbon fiber composite clamping petals through hoops, a thread of the projectile support is formed by machining and combining a plurality of carbon fiber mold pressing plates with different laying layer angles and laying layer thicknesses, and an outer shell is formed by short carbon fiber prepreg yarns through mold pressing. The preparation method comprises the steps of projectile support design, thread preforming, clamping petal forming and the like. The preparation method provided by the invention is simple in process, the prepared projectile support is light in mass and small in inert mass, and compared with a projectile support made of a metal material, the initial velocity of ammunition is higher and the firing range is farther under the same working condition. In addition, the thread of the projectile support is formed by the continuous carbon fibers in advance, the thread is high in strength and good in consistency, a bullet core can be better supported during launching in a chamber, and the projectile support has the advantage of being higher in reliability.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an empennage-stabilized shell-piercing shell and a preparation method thereof. Background technique [0002] The bullet holder is an important part of the tail-stabilized shell-piercing projectile. At present, most of the bullet holders used are saddle-shaped structures divided into three or four flaps along its longitudinal axis. When the armor-piercing projectile is launched, three or four The clasp can hold the projectile tightly so that it can obtain the best initial velocity, support and guide the flight. After being ejected from the chamber, the bullet holder is subjected to the resistance of the oncoming airflow and the aftereffect of the gunpowder gas, and the combined valve opens and separates from the bullet body. During this process, the tooth bud is the main bearing part. [0003] At present, the material of the bullet holder of the armor-piercing bullet ...
