Embodiment 1

[0029] This embodiment relates to a preparation method of bulletproof composite armor, comprising the following steps:

[0030] S1, take several sheets of ultra-high molecular weight polyethylene UD cloth (area density 16kg / m 2 ), according to the axial 0° / 90° cross-lamination and laying, to obtain the laminate 4, the thickness of the laminate 4 is 10mm, and then fix the outer edge of the laminate with a clamp;

[0031] The pressure-resistant rubber pad 3, the bulletproof ceramic plate (0.08m 2 Single soldier chest plate) 7 and aramid cloth 6 coated with adhesive 5 on both sides are aligned and stacked and then placed on the lower thermal head 2, such as figure 2 As shown; the lower thermal head 2 is heated, and the temperature is maintained at 150 ° C; the upper thermal head 1 is heated to 150 ° C, and then the laminate 4 is pressed down in the direction of the downward thermal head 2, and the pressing pressure is 5 MPa, so that the laminate 4 Deformation occurs, and the l...

Embodiment 2

[0035] This embodiment relates to a preparation method of bulletproof composite armor, comprising the following steps:

[0036] S1, take several sheets of ultra-high molecular weight polyethylene UD cloth (area density 16kg / m 2 ), according to the axial 0° / 90° cross-lamination and laying, to obtain the laminate 4, the thickness of the laminate 4 is 10mm, and then fix the outer edge of the laminate with a clamp;

[0037] Such as Figure 4 As shown, the aramid cloth 6 coated with adhesive 5 on both sides and the bulletproof ceramic plate (0.08m 2 Individual chest plate) 7 bonded, then aligned and placed on the composite 4, then stacked on the top of the bulletproof ceramic plate 7 pressure-resistant rubber pad 3, and then aligned and placed on the lower thermal head 2, the upper thermal head 1 Move downward to the direction of the thermal head 2 until the upper thermal head 1 is bonded to the pressure-resistant rubber pad 3; the lower thermal head 2 is heated to 150°C and pres...

Embodiment 3

[0041] This embodiment relates to a preparation method of bulletproof composite armor, comprising the following steps:

[0042] S1, take several sheets of ultra-high molecular weight polyethylene UD cloth (area density 16kg / m 2 ), according to the axial 0° / 90° cross-lamination and laying, to obtain the laminate 4, the thickness of the laminate 4 is 15mm, and then fix the outer edge of the laminate with a clamp;

[0043] The bulletproof ceramic plate (0.5m 2 Equipment bulletproof plate) 7 and aramid cloth 6 coated with adhesive 5 on both sides are aligned and stacked and placed on the lower thermal head 2, the lower thermal head 2 is heated, and the temperature is kept at 150°C; the upper thermal head 1 is heated After reaching 150°C, press down on the laminated product 4 in the direction of the thermal head 2, and the pressing pressure is 5Mpa, so that the laminated product 4 is deformed, and the lengths of the laminated product 4 in the X direction and the Y direction are st...

Abstract

The invention discloses bulletproof composite armor and a preparation method thereof, and belongs to the technical field of composite materials. The preparation method of the bulletproof composite armor comprises the following steps that S1, multiple layers of ultra-high molecular weight polyethylene UD cloth are stacked, the outer edge of a stacked object is fixed through a clamp, and then the stacked object is heated and stretched in the horizontal direction to generate prestress; and S2, under the condition that the heating state and the stacked object stretching state are kept, a bulletproof ceramic plate, an adhesive, a crack arrest layer, an adhesive and the stacked object are vertically pressurized, hot-pressed and compounded in the Z direction, finally cooling is conducted to the room temperature, and the bulletproof composite armor is obtained. The prepared bulletproof composite armor is of a ceramic layer/crack arrest layer/ultra-high molecular weight polyethylene UD cloth stacked layer structure, the ultra-high molecular weight polyethylene UD cloth stacked layer has certain prestress, the sinking degree can be reduced after the bulletproof composite armor is stuck by a bullet, and therefore a better protection effect is achieved.

Description

technical field [0001] The invention relates to a technology in the field of composite materials, in particular to a bulletproof composite armor and a preparation method thereof. Background technique [0002] The traditional composite method of bulletproof inserts is to apply glue on the bonding surface of ceramic and PE laminates, and then bond bulletproof ceramics and PE laminates together by applying external force and keeping the glue dry. This composite process method may cause gaps or cavities between the bulletproof ceramics and PE laminates due to the slight difference in curvature. The bulletproof performance of the bulletproof insert that is not completely formed as a whole will decrease or even fail. The stability and reliability of the product cannot be guaranteed. Therefore, in order to improve the stability and reliability of bulletproof board composites, bulletproof ceramics, adhesive film and PE laminates are placed together in an autoclave, and the product ...
