Problems solved by technology

Due to the influence of their own physical and mechanical properties and economic costs, ceramics and FRP materials, for example, ceramics have high hardness, but low tensile strength, and are easily broken under external influences. In addition, the economic cost is high, and its application range has been limited. limit

Abstract

The invention discloses an iron-based alloy reactive armor shell with low collateral damage. The shell comprises a reactive armor housing and a reactive armor chamber shell positioned in the reactive armor housing, and is prepared by iron powder of 70-97 parts by weight, copper powder of 2-30 parts by weight and graphite powder of 0.3-1 part by weight through a powder metallurgy method and a subsequent processing technology. A preparation method adopts the powder metallurgy method, and comprises such processes as powder mixing, compression molding, sintering, shaping, oil containing, cleaning, surface treatment and welding. The reactive armor shell prepared by the method is lower in fragment collateral damage effect after the reactive armor effect, and has such advantages as high strength, low cost, controllable shape and batch production.

Description

technical field [0001] The invention relates to the field of armor protection of armored vehicles, in particular to an iron-based alloy reactive armor shell with low incidental damage and a preparation method thereof. Background technique [0002] Reactive armor, also known as explosive reactive armor, is widely used in the protection of modern armored vehicles due to its advantages of high protection efficiency, light weight, convenient loading and unloading, and low cost. The traditional explosive reactive armor structure is a "sandwich" structure composed of two layers of symmetrical or asymmetrical homogeneous steel plates sandwiching explosives, that is, it is composed of a front plate and a back plate sandwiching explosives. When the incoming jet hits the reactive armor with a certain inclination angle at high speed, the middle explosive layer will be detonated. Under the action of high-pressure and high-speed detonation products, the homogeneous steel plate moves at h...
