Composition of helmet

The modern helmet is mainly composed of the helmet shell, lining and suspension system. Due to the different requirements for the use of various activities, the structure and style of the helmet are many.

Typically, the helmet's shell is made of a higher strength material, such as metal, engineering plastic, Kevlar fiber, etc., through its deformation to absorb most of the impact; The lining material has the functions of absorbing sweat, keeping warm and absorbing shock, and the military helmet often has the function of further slowing the impact force and preventing the shell fragments from injuring the head. The suspension system is the part between the shell and the lining, which can usually be adjusted to accommodate the wearer's different head shape.

Some special purpose helmets are also equipped with headphones, microphones, and jacks for installing cameras, lighting torches and other additional equipment.
