We all have questions in mind about the process and engineering behind body armor and bulletproof clothing. Below is the process step by step that how the raw material turn in to a bulletproof vest.
The very first step for making a bulletproof vest is the fiber which actually plays an important role as it gives the base to be bulletproof. These extremely durable fibers are weaved through a special machine that wraps and stretches them into yarn. .
At this step large spools of the basic fibers are weaved into cords and yarn. The yarn is a long in length of interlocked fibers, which are suitable in the production of fabrics and sheet material. The threads that make bullet proof textiles are produced by spinning a solid fiber from a liquid chemical blend.
The yarns are woven into a sheet material and make it capable of stopping bullets. This is also used to make the bulletproof panels. After this the sheet material are put on rolls around in length like rolls of any other textile. A soft vest is made of many layers of woven or laminated fibers, which are lightweight but strong. The fabric absorbs impacts from gun-fired projectiles and shrapnel fragments from explosions.
Cutting The Material
With the help of large patterns or cutting machines multiple layers of ballistic sheets are cut at once. Bulletproof vest is consists of front and rear panels that are different shape and size than a normal garment. The ballistic panels used in bulletproof clothing are made of multiple layers and have passed the extensive testing to identify the proper thickness. The thickness is depends on what level of protection is required.
Sewing of Panels
The fabric layers are stitched together to manufacture the ballistic panel. To sew the layers together, a stencil is placed on top of the layers and the chalk is rubbed to expose the areas of the panel to cut and sew.
After stitching of the layers of ballistic material they need to put in a protective cover. The cover can be heat-sealed or ultrasonic sealed in order to protect the ballistic material from water and humidity. This is called the basic ballistic panel which has bullet resistant qualities.
The ballistic panels are then fitted into the carrier made of strong Aramid fabric. A ballistic carrier has pockets inside to insert the panels. Also these carriers are designed in such manner which hold the panels in proper position on the body.
