Almost all Motorcycles can travel the same speeds or faster than an cars but there is nothing between the motorcyclist and the environment except proper clothing and safety appliances. This means that the potential is high for heavy injury or fatality in head impact accidents. Helmets are intended to give protection to the head from unexpected impact against hard surfaces and sharp objects. Some types of helmets do a better job than others.
The majority of sports helmets are made of fiberglass. While offering some protection, in most situations fiberglass isn't powerful enough to withstand the kind of shattering impact that can come from a motorcyclist's head hitting pavement. {However , a helmet made of carbon fiber is a different story.
Carbon fiber is very fine strands of carbon that can be twisted together and then woven. Even though each strand of carbon fiber is thinner than a human hair, it is extremely strong. Carbon fiber is five times as strong as steel but only about one in three as heavy. It also has excellent tensile strength. This implies that carbon fiber can 'give' or stretch quite a lot before it comes apart. All of these features indicate that carbon fiber helmets are better able to absorb more of the force of an impact than most other helmet materials. It's also a lot less likely that sharp things can penetrate a carbon fiber helmet shell.
Carbon fiber helmets are sometimes manufactured by placing layers of carbon fiber in a helmet shell mold and then coating the fibers with an acrylic resin or some other sort of plastic. In a few cases, this process is done under high pressure to make an even stronger laminate. The resulting products are helmets that are lightweight, extremely strong barriers between heads and hard surfaces.
All States with helmet laws on the books require motorcyclists to wear helmets that meet safety standards established by the U.S. Department of transport ( DOT ). These standards include things like minimum visibility, impact force assimilation, and amount of face/head covered. Before the appearance of carbon fiber helmets, helmets that met all the licensed DOT factors could be quite bulky and heavy. The use of carbon fiber has allowed more latitude among helmet designers to form some smaller, more streamlined styles that are cushty for the rider but still supply the safety the DOT requires.
