Helmets made to meet the standards of the DOT can be found in materials such as plastic, fiberglass, and polycarbonate. These tough outer shells are designed to protect the head from impact trauma. However,s novelty half helmet does not match the DOT requirements due to their smaller size.
The interior of a DOT approved product is as important as the shell. Expanded polystyrene foam, or EPS, is the standard liner for helmets it is used to prevent brain injury from occurring. The foam is used to aid in absorbing the impact force of a crash. Skull Crush uses a typeof memory foam used by Nasa to protect space vesels.
Most people believe that the need to wear head gear is to prevent injury to the head, this is incorrect. The majority of fractures to the bones of the skull are not fatal by themselves it is the damage to the soft tissue that develop the health concerns. The brain is the primary focus for protection.
During an accident the head can be subject to impact. The impact itself may fracture the bones of the head, but the result of this jerking motion sends the brain slamming against the interior of the head and causes damage. For this reason the DOT requires an inner lining to the head gear that will absorb and cushion the blow.
Lining density varies widely. The idea behind the lining is the thicker it is, the higher the protective ability. The foam crushes with the impact of an accident, this provides protection for injury in much the same way as a person jumping into an airbag. Skull Crush helmets are lined with a higher quality memory type foam in comparison to standard EPS.
There are specific requirements of its hard outer shell. The material must not only protect, but also disperse the blunt force of the impact site. Plastic and fiber materials are known to be the strong enough to withstand the hit while also delivering the pliable properties to lessen the effects of any impact.
A crushing action is considered the best way to address the force of an accident this has been performed with the use of carbon fiber and Kevlar. The use of these specific materials provides a lighter product than plastic or fiberglass. Concerns over the strength of these lighter materials disappear once a person understands these helmets are recognized as some of the hardest available.
The great features of these helmets cause people to wonder why the DOT does not accept this design. The answer lies not in the quality of its materials, but the amount of coverage a person receives when wearing this head gear. The low profile style while fun and well-liked does not fall in line with DOT's bulky helmet standards.
The DOT will not consider the strength of a skull crush carbon fiber half helmet as a regulation protective device. The materials are not in question, since they are top tier, but the low profile which this style provides does not coincide with the thick styrofoam design that DOT prefers.
