Problems solved by technology

[0003] However, due to the low bonding strength of the adhesive, the armor-piercing process of the warhead will easily cause the plate structure between two adjacent layers to separate, making the ballistic performance of the composite armor plate low

Embodiment

[0018] Please refer to the attached Figure 1-2 , this embodiment provides a composite armor plate with a ceramic rod 100 as a sandwich, including:

[0019] The armor plate layer 200 and the ceramic rod 100, the armor plate layer 200 wraps the ceramic rod 100, and the ceramic rod 100 itself includes the ceramic rod core 110 and the outer composite layer 120, which are formed by integral hot pressing and sintering.

[0020] The composite layer structure is a multi-layer superposed composite structure of titanium carbide and aluminum oxide.

[0021] Wherein, in the direction away from the ceramic core, the content of titanium carbide in the multi-layer composite ceramic layer increases, and the content of alumina decreases.

[0022] Among them, the ceramic rod 100 is in the shape of a round rod.

[0023] The number of ceramic rods 100 is several layers, each layer is several, and several ceramic rods are arranged at intervals along the thickness direction of the armor plate la...

Abstract

The invention discloses a composite armor plate with an aluminum oxide ceramic rod as an interlayer and a preparation method of the composite armor plate. The composite armor plate comprises an armor plate layer and the ceramic rod. The ceramic rod is formed by compounding pure aluminum oxide ceramic at the core part and an aluminum oxide ceramic and multiphase ceramic composite layer on the surface layer of the pure aluminum oxide ceramic through hot pressing sintering. Wherein the composite layer is formed by sintering titanium carbide and aluminum oxide. The wettability of titanium carbide in the composite layer and molten steel is good, and welding with the poured molten steel is facilitated. The aluminum oxide core part and ceramic in the composite layer are made of the same material, and sintering formability is good. According to the composite armor plate with the aluminum oxide ceramic rod as the interlayer and the preparation method of the composite armor plate, the connecting strength between the ceramic rod and the armor plate layer is high, and the bulletproof performance of the composite armor plate is good.

Description

technical field [0001] The invention relates to the technical field of armor protection, in particular to a composite armor plate with a ceramic rod as an interlayer and a preparation method thereof. Background technique [0002] As a common armor protection equipment, composite armor plate is required to have excellent anti-ballistic performance. The existing composite armor plates are generally multi-layer flat plate structures stacked in sequence along the thickness direction, and most of the adjacent two-layer plate structures are glued together. [0003] However, due to the low bonding strength of the adhesive, the armor-piercing process of the warhead will easily separate the plate structure between the two adjacent layers, resulting in low elastic resistance of the composite armor plate. SUMMARY OF THE INVENTION [0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a composite armor plate with a ceramic rod as ...
