Bulletproof glass structure

Bulletproof glass is first explained in many articles, for example, at least three layers or more of ordinary glass glued together; the structure shown in the figure below is glass + film + glass + film + glass. Therefore, only after we understand the structure of the bulletproof glass that can we know the approximate weight of the bulletproof glass under a fixed size.

Density of bulletproof glass

The density relationship of bulletproof glass also needs to start by understanding ordinary glass. Since it is composed of ordinary glass or PC composite materials, we roughly calculate the density of ordinary glass (2.5g/c㎡), such as 25mm bulletproof glass 8+ The weight of the 8+8 structure is 2.5 (density/g/c㎡)*25 (thickness/mm)=62.5kg/㎡. Therefore, we have mentioned the self-weight of bulletproof glass in the application and guidance and suggestion process. If the size is too large, it will be difficult to handle manually during the installation process; the size of the bulletproof glass of the bank is also standardized within the range of 1200*1800mm Is the best.

Bulletproof glass weight

After understanded the density and structure of bulletproof glass, the weight calculation formula: KG=2.5*thickness*square. So for example, 1.8*1.2m bulletproof glass with 32mm thickness in GA165-2016 latest bulletproof glass standard weight is: 1.8*1.2*2.5*32=172.8 kg, the total weight is nearly 385 pound, which is close to the weight of three adults. Therefore, we try our best to ensure the application of glass installation design in the design process to avoid affecting subsequent material installation.
