Composite armor plate containing titanium alloy packaging and splicing ceramic panel and preparation method of composite armor plate

The invention provides a composite armor plate containing a titanium alloy packaging and splicing ceramic panel and a preparation method of the composite armor plate. The composite armor plate comprises a panel layer, a first transition layer, a second transition layer and a PE back plate layer which are sequentially connected in an overlapped mode. The panel layer is composed of at least one layer of ceramic panel packaged by titanium alloy, each layer of ceramic panel is formed by splicing and bonding a plurality of large and small ceramic blocks which are isosceles trapezoid hexahedrons according to a certain splicing rule, and the side, facing the human body, of each layer of ceramic panel forms a flat plane. A plurality of isosceles trapezoid protrusions and a plurality of isosceles trapezoid recesses which are arranged at intervals in the transverse line direction and the longitudinal line direction are formed in the bullet facing side. The armor plate is easy to machine and assemble and low in process
