Problems solved by technology

[0003] However, casting, forging and powder metallurgy can only realize the manufacture of layered titanium matrix composite armor, and it is impossible to prepare armor layers with complex structures between layers.
Compared with titanium alloys, titanium-based composite materials have higher strength, but less toughness. After being hit by a single bullet, the compressive stress wave generated quickly spreads to the surroundings, and the surrounding materials are pulverized and damaged, and the crack expansion area is large, which makes the armor material resistant to multiple bullets. Significantly reduced strike capability

Abstract

The invention provides a titanium-based composite armor and a manufacturing method thereof. The titanium-based composite armor comprises an upper layer, a middle layer and a lower layer, wherein the upper layer and the lower layer are titanium alloy layers, the middle layer is a titanium alloy and ceramic composite layer and is provided with a titanium alloy space lattice structure, and the titanium alloy and ceramic composite layer is divided into a plurality of unit modules by the space lattice structure. The manufacturing method of the titanium-based composite armor comprises the steps of designing a sandwich structure with the space lattice structure through CAD software and forming the sandwich structure through the electron beam selective melting technology; filling the formed sandwich structure with titanium alloy and ceramic mixtures; carrying out hot isostatic pressing for obtaining the titanium-based composite armor. The titanium-based composite armor is of a multilayer structure, the middle layer is provided with the titanium alloy space lattice structure, titanium-based composite modularization is realized, and therefore the destruction range of shooting of a single bullet can be limited, and the multiple bullet shooting resistance of armor material can be improved.

technical field [0001] The invention relates to a titanium-based composite material armor and a manufacturing method thereof, belonging to the technical field of composite material components. Background technique [0002] At present, the preparation methods of titanium matrix composites mainly include casting, forging and powder metallurgy. In the titanium alloy smelting stage, ceramic powder is added to the melt, or ceramic powder and titanium alloy powder are mixed for powder metallurgy molding, so as to adjust the strength and toughness of titanium-based composite materials for armor protection. [0003] However, the casting, forging and powder metallurgy methods can only realize the manufacture of layered titanium matrix composite armor, and cannot prepare armor layers with complex structures between layers. Compared with titanium alloys, titanium-based composite materials have higher strength, but less toughness. After being hit by a single bullet, the compressive str...
