This is Carapace Armor. Carapace armor includes two types of protection at once, the carapace itself, it has a purple color, is made of high-strength and at the same time light alloy, and also from scales, the scales are made of carbon fiber with numerous titanium filaments, due to which such scales are elastic and very durable at the same time. This type is advanced, since it is very light and durable, but such armor, firstly, is expensive, and secondly, its manufacture is very difficult due to the production of special scales and alloys.
