There are several types of hard armor. Most of them are made of rigid, reinforced plates and are worn by combat soldiers and police tactical units. These plates are designed to protect the wearer against deadly weapons such as knives. However, these types of armor are not easy to conceal, and not all hard armor is rifle-rated. Regardless of the type of hard armor you wear, you should know what to look for before you buy one. Here are a few things to look for in hard armor.
Pure Polyethylene plate is the weakest form of hard armor. It can withstand a single round of M855 or 7.62×39 Mild Steel Core, but will be damaged if struck by another projectile. The reason it doesn’t tear is because it’s made of twisted fibers that provide extra strength and density. The fibers are also covered in plastic, resin, or other materials. These materials are made of multiple layers of aramid fibers.
Another type of hard armor is made from composites. Polyethylene is a popular choice among armor makers because it’s cheap and versatile. It can withstand heat, cold, and other extreme conditions, but is still relatively lightweight. Polyethylene also weighs a lot less than steel, which makes it less expensive. Further, if you’re interested in purchasing hard body armor, be sure to ask your military supplier about the certifications for your equipment.
