specific Embodiment approach 1

[0017] Specific embodiment 1: In this embodiment, a wide volume fraction layered gradient boron carbide aluminum matrix composite material is composed of a panel, a back panel and a transition intermediate layer; the transition intermediate layer is arranged between the panel and the back panel; the panel It is made of 70%-90% boron carbide and 10%-30% aluminum-containing material by volume fraction; the back plate is made of 0%-40% boron carbide and 60%-100% aluminum-containing material by volume fraction; The transition intermediate layer is a multi-layer boron carbide aluminum matrix composite material, and the volume fraction of boron carbide in each layer of boron carbide aluminum matrix composite material decreases equigradiently from the face plate to the back plate; the aluminum-containing material is aluminum or aluminum alloy.

specific Embodiment approach 2

[0018] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the panel is made of 70% to 90% boron carbide and 10% to 30% aluminum-containing materials by volume fraction; The volume fraction of boron carbide in the boron-aluminum matrix composite material is reduced layer by layer until the volume fraction of boron carbide in the back plate is 0-15%. Others are the same as the first embodiment.

specific Embodiment approach 3

[0019] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the panel is made of 70% boron carbide and 30% aluminum-containing materials by volume fraction; each layer of boron carbide-aluminum matrix is ​​composited from the panel to the back plate The volume fraction of boron carbide in the material is reduced layer by layer until the volume fraction of boron carbide in the back plate is 15-20%. Others are the same as those in Embodiment 1 or 2.

Abstract

A wide volume fraction layered boron carbide aluminum matrix composite material and a preparation method thereof, which relate to a layered functionally graded boron carbide aluminum matrix composite material and a preparation method thereof. The invention aims to solve the problems of poor bulletproof effect of single volume fraction homogeneous aluminum matrix composite material, low bulletproof panel volume fraction in bulletproof layered gradient aluminum matrix composite material and low interface bonding strength of simple laminated protective structure. The panel is made of 70% to 90% boron carbide and 10% to 30% aluminum-containing materials according to the volume fraction; the transition middle layer is composed of multi-layer boron carbide aluminum matrix composite materials, and each layer of boron carbide aluminum matrix composite materials is from the panel to the back panel The volume fraction of boron carbide in the medium gradually decreases layer by layer; method: preparation of prefabricated body powder; second, laying out layer by layer to prepare prefabricated body; third, molten aluminum liquid; In the body gap, hold the pressure, release the mold, and obtain the layered gradient B 4 C / Al composites. The invention is used for preparing armor structure materials.

Description

technical field [0001] The invention relates to a layered functional gradient boron carbide aluminum matrix composite material and a preparation method. Background technique [0002] With the development of science and technology, the power of anti-armor weapons is increasing day by day, and the requirements for armor protection are getting higher and higher. Improving the protective effect simply by thickening the armor protection layer is bound to seriously affect the combat mobility and rapid response capabilities of the weapon system. In order to meet the high mobility and strong defense requirements of combat weapons in the future battlefield, all military powers in the world today are committed to developing armor with high strength, high hardness, high toughness and low density (that is, "three highs and one low"). [0003] At present, the most widely used armor structural material is ceramic / metal composite armor. Although this kind of armor has relatively excellent...
