Embodiment 1

[0031] In this example, see figure 1 , a lightweight functionally graded composite bulletproof armor plate, mainly comprising a bulletproof ceramic plate (1), a shape memory alloy layer (2) and an ultra-high molecular weight polyethylene plate (3), wherein the shape memory alloy layer (2) is arranged on the bulletproof Between the ceramic plate (1) and the ultra-high molecular weight polyethylene plate (3), the shape memory alloy layer (2) is used as the core plate to form a composite structural plate, see figure 1 , between one side surface of the shape memory alloy layer (2) and the bulletproof ceramic plate (1), and between the other side surface of the shape memory alloy layer (2) and the ultra-high molecular weight polyethylene plate (3) Between them, there is an adhesive adhesive layer (4) composed of two-component fireproof adhesive. The adhesive adhesive layer (4) can connect the two layers of the shape memory alloy layer (2) to the bulletproof ceramic plate (1) and th...

Embodiment 2

[0048] This embodiment is basically the same as Embodiment 1, especially in that:

[0049] In this embodiment, bulletproof ceramics select B 4 C ceramics, the thickness of the bulletproof ceramic plate (1) is 10mm, the ultra-high molecular weight polyethylene plate (3) is made by hot pressing of ultra-high molecular weight polyethylene without weft cloth, and the thickness of the ultra-high molecular weight polyethylene plate (3) is 10mm, The shape memory alloy layer is made of 1:1 nickel-titanium alloy, and the thickness of the shape memory alloy layer is 1mm. In each embodiment of the present invention, the surface size of the lightweight functionally graded composite bulletproof armor plate is 300×300mm 2 .

[0050] In this embodiment, a method for manufacturing a lightweight functionally graded composite bulletproof armor plate of this embodiment includes the following steps:

[0051] a. Preparation of shape memory alloy layer:

[0052] Prepare a 1mm thick nickel-titani...

Abstract

The invention discloses a lightweight functionally graded composite bulletproof armor plate and a preparation method thereof. The lightweight functionally graded composite bulletproof armor plate comprises a bulletproof ceramic plate, a shape memory alloy layer and an ultrahigh molecular weight polyethylene plate, and the shape memory alloy layer is arranged between the bulletproof ceramic plate and the ultrahigh molecular weight polyethylene plate; the shape memory alloy layer serves as the sandwich plate, the hyper-elastic effect of the shape memory alloy layer is exerted, the composite plate with a sandwich structure is formed, the defects of an existing bulletproof armor material are overcome, the weight is greatly reduced compared with bulletproof steel under the condition of the sameprotective capacity, and then the high practical value of the bulletproof composite armor plate is achieved. The bulletproof composite armor plate can be used as a preparation material of armor equipment, and is applied to the fields of armor equipment including armored vehicles, naval vessels, bulletproof clothes, bulletproof helmets and the like.

Description

technical field [0001] The invention relates to the technical field of special armor materials, in particular to a lightweight functional gradient composite bulletproof armor plate and a preparation method thereof. Background technique [0002] The armor protection structure is the key to restricting the survivability of the battlefield. Whether it is an individual soldier, or a battlefield assault weapon such as an armored combat vehicle or an armed helicopter, the protection performance is the most basic and critical performance in its survivability. Modern warfare requires troops to have rapid maneuverability, which has become one of the core indicators of weaponry and equipment development. Improving armor protection performance by increasing the thickness will seriously reduce the maneuverability of weapons and equipment. In addition, ceramic, metal, and composite material protection structures have reached their performance limits, making it difficult to further reduce...
