Penetration blasting warhead with titanium alloy matrix containing active fragment inclusions and preparation method

Abstract

The invention provides a penetration blasting warhead with a titanium alloy matrix containing active fragment inclusions and a preparation method. A partition plate is arranged between a warhead and a shell; the warhead is internally provided with front-section explosive; the shell is internally provided with rear section explosive; the shell comprises a titanium alloy matrix and active fragments, wherein the titanium alloy matrix comprises a titanium alloy thin-wall cylinder framework and titanium alloy metal powder, array empty grooves are formed in the cylinder wall of the titanium alloy thin-wall cylinder framework, and the active fragments are bonded in the array empty grooves; the titanium alloy thin-wall cylinder framework, the active fragments and the titanium alloy metal powder are made into the shell by pressing; the front end of the shell is provided with internal threads connected to external threads at the tail of the warhead; and the tail end of the shell is in threaded connection with a body connecting sleeve and an end cover, and the body connecting sleeve is filled with a fuse. According to the penetration blasting warhead with the titanium alloy matrix containing active fragment inclusions and the preparation method, the 3D printing thin-wall framework is adopted for filling and fixing the active fragments, convenience is provided for design and manufacturing, a framework material is the same as the powder metallurgy shell base material, the interior of the shell has good compatibility, and the structural strength of the shell is guaranteed.

Description

technical field [0001] The invention belongs to the field of fragment warheads, and in particular relates to a penetrating blast warhead whose titanium alloy matrix contains active fragment inclusions and a preparation method. Background technique [0002] Active structural materials are a new class of multifunctional materials that have emerged in recent years to meet the needs of national defense engineering. Foreign countries generally call this material ReactiveMaterials (reactive materials), also known as Impact-initiatedEnergeticMaterials (impact-initiated energetic materials), (hereinafter Collectively referred to as active materials), the fragments prepared by using active materials (hereinafter collectively referred to as active fragments) can not only have enough kinetic energy to penetrate the target but also produce additional chemical reactions and release energy to generate greater damage to the target during the penetration process of the target.
