The liner and outer shell of a helmet are tuned together to give an optimal crash response. Research with military helmets is producing new materials, including ultra-high-molecular-weight polyethylene or UHMWP that are more effective for preventing bullets from penetrating than the …
When you are wearing a ,helmet, during a fall or crash, the force of impact is distributed over the surface of the ,helmet,, rather than concentrated on the head. In addition, the thick plastic foam (firm polystyrene) ,inside, the hard outer shell of a ,helmet, provides protection that cushions the blow.
Cloth and leather helmets were then the safety standard, but deaths from football-related head injuries were common. Hardshell football helmets were invented in the 1930s and significantly reduced the amount of impact the skull and brain endured during gameplay.

Unvented ,helmets, are better for use in areas where you require protection from chemicals and liquids with many unvented ,helmets, protecting against molten metal and electric shocks of 440V ac.
Materials Used in Motorcycle Helmets Motorcycle helmets consist of a shell, a foam layer and padding. The shell disperses the impact across a wide area, while also preventing anything from piercing the helmet. Meanwhile, the foam absorbs as much of the impact as possible, so your head doesn't have to.
The middle layer of the helmet is what should absorb the majority of the impact from a fall or accident. Liners can be made from expanded polystyrene—which is a very lightweight product made of expanded polystyrene beads—made of more than 95 percent air and only about 5 percent foam.
