Kevlar helmets are used by more than just soldiers. Kevlar is used in motorcycle helmets and police officer headgear as well. The process of manufacturing a Kevlar helmet consists of layering strips of Kevlar over a lightweight frame.
History of the Kevlar Helmet
The Kevlar helmet was first used by the United States military in 1976 during the Vietnam War. The development team that created the Kevlar helmet initially wanted to make it lighter than the steel helmet used by soldiers in previous wars. When the helmets were finished they ended up having the same weight, but offered greater protection and balance.
The lightweight material that forms the foundation of a Kevlar helmet is usually a synthetic ballistic material. Layer upon layer is then grafted to this foundation until the helmet is sufficiently durable to protect the wearer from cranial damage from shrapnel, bullets or other heavy impact.
Benefits of Kevalr
The primary advantage of Kevlar is that it is lighter and more flexible than steel. It offers high tensile strength and is also considerably more flexible.
