Bulletproof plate of high strength polyurethane/fiber/ceramic structure

Abstract

The invention relates to the field of bulletproof equipment and discloses a bulletproof plate of a high strength polyurethane / fiber / ceramic structure. The bulletproof plate comprises an inner layer and a coating layer. The inner layer comprises a ceramic bulletproof plate (1) and a fiber cloth laminated plate (2). The coating layer coats the outer side of the inner layer. Polyurethane coating layers (4) of different thicknesses are coated to different surfaces of a fiber cloth coating layer (3). Human tissues and bones of a wearer are prevented from being damaged effectively. The adjacent bulletproof plates fit tightly, so that local weakness caused by gaps among the bulletproof plates is prevented effectively. The polyurethane material coated to the outer surface resists atrocious weatherand environments effectively, so that the service performance of the buffet plate is improved.

Description

technical field [0001] The invention relates to the field of bulletproof equipment, in particular to a high-strength polyurethane / fiber / ceramic structure bulletproof plate. Background technique [0002] At present, the composite method of bulletproof inserts is mostly made by directly bonding the whole ceramic plate and the high-performance fiber fabric laminate through an adhesive, or directly bonding small pieces of spliced ​​ceramics to the fiber fabric laminate; After the impact, it is very easy to cause the overall fragmentation of the ceramic plate, which affects the bulletproof effect; and the bulletproof insert prepared by the latter is partially weak due to the gap between the ceramic sheets. When the bulletproof insert is impacted by the bullet, it is easy to cause the bullet. run through. [0003] In combat operations, individual protective plates need to be worn on soldiers to enter and exit various battlefield environments. It is easy to encounter harsh weather...

[0002] At present, the composite method of bulletproof inserts is mostly made by directly bonding the whole ceramic plate and the high-performance fiber fabric laminate through an adhesive, or directly bonding small pieces of spliced ​​ceramics to the fiber fabric laminate; After the impact, it is very easy to cause the overall fragmentation of the ceramic plate, which affects the bulletproof effect; and the bulletproof insert prepared by the latter is partially weak due to the gap between the ceramic sheets. When the bulletproof insert is impacted by the bullet, it is easy to cause the bullet. run through

[0003] In combat operations, individual protective plates need to be worn on soldiers to enter and exit various battlefield environments. It is easy to encounter harsh weather and environments such as high temperature, high humidity, soaking water, rain, snow, freezing, and sun exposure. Bulletproof ceramics, metals, etc. 1. When the polymer fiber is in this environment for a long time, its structure and performance will undergo some changes, such as aging, rust, etc. At the same time, problems such as water absorption, weight gain, and cold surface will also affect the wearing experience of soldiers.
