The DOT has established a number of design requirements for a helmet to be considered safe for use in the event of an accident. There are a number of materials that are considered acceptable, including fiberglass and or plastic. The strength of a skull crush carbon fiber half helmet is not acceptable to the standards of the DOT due to it's slim low-profile design.
In addition to the strength of the DOT shell, the inner lining of expanded polystyrene foam plays an important role. EPS linings are developed to aid in the prevention of brain injuries. The material is developed to limit the effects of an impact on the soft brain tissue.
It is a common misconception that that purpose of head gear is to protect the head from injury. The fact is that fractures to the skull by themselves are usually not the cause of serious harm. The protection is instead aimed at the brain.
An accident can include impact to the head in a number of different angles. The incident can fracture the bone, but the concern is the movement of a person's brain within the head which can force it to slam against the sides. This movement is one of the primary reason the brain is damaged, and the key factor to the guidelines from the DOT for linings to cushion the action.
EPS is provided in many different densities. The thicker the lining, the greater the protection to the individual wearer is the principle on this material. The material is made to crush when there is an impact trauma, much like a person jumping into an airbag from heights. The lining that is placed into the helmets is reported to be more impact resistant that standard foams that are used.
The hard outer shell must also be pliable. These materials need to be able to bend to the force of the impact, displacing the force and minimizing the overall effect of an incident. Plastic and other fiber material have been found to be sturdy enough to withstand the brunt force and provide the necessary absorbing properties to deliver the necessary results.
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.
With the combination of these high quality features for these helmets people often wonder why the DOT does not recommend them. The answer is simply a matter of size. The low profile design does not comply with DOT's bulky styrofoam specifications.
The strength of a skull crush carbon fiber half helmet is undeniable, but the style does not meet the thick size requirements set by the DOT. The quality of these helmets is well recognized by the motorcycle community. Individuals who choose to use this style need to understand that the safety rating has not been tested by DOT, but have great quality.
