The helmet warehouse offer fewer material options as they are intended for lower cruising speeds.
At certain speeds, thermoplastic helmets may be as secure as premium composite fiber ones. To provide the same level of protection, thermoplastic helmets have to be thicker and more substantial. Helmets of lighter weight are better for riding, especially if your riding is aggressive.
Composite Materials
The process of creating composite fiber helmets involves placing layers of fiber strands in a mold, adding resins, or other fillers, and heating it. The process can be repeated using strands at different angles until a weave pattern is established and very high strength is achieved. Composite fiber helmets are much more expensive than traditional helmets because they require a lot of labor and cost more materials.
Composite fiber helmets come in a range of materials, such as Kevlar fiber, fiberglass, and carbon fiber. Remember that helmets described as “fiberglass”, carbon fiber, etc. may include a mixture of different fiber types.
Unless otherwise indicated, official helmet designations will follow the most predominant material in any composite mix. As an example, a carbon fiber helmet will include more carbon material than other helmets.
Fiberglass
Although fiberglass materials are generally inexpensive, they can easily be molded into strong and lightweight forms. The fiberglass material has a lot of admirers who appreciate its ability to balance flexibility with hardness.
Many helmets with fiberglass weave patterns include high-strength materials such as carbon fiber or Kevlar. Helmet costs rise when more of these types of materials are added.
The advantage of fiberglass composite helmets over traditional steel helmets is their greater flexibility under impact. This allows shock waves to spread out more evenly. Because of its brittleness, the helmet shell is more susceptible to cracking from impact. In these cases, the helmet shell will crack and a larger part of the Styrofoam layers can help it collapse. Your head won’t be in direct contact with the hard shell. This allows for a lighter helmet and a smaller overall size.
Because carbon atoms can bond to each other in crystal formations, it is possible for a naturally occurring high-strength link to form. A reinforced “carbon fiber” is a fabric made from thousands of these high-quality fibers.
Carbon fiber boasts the advantage of being very strong yet extremely lightweight. It is strong in tensile strength and has great compression strength. These characteristics make helmet shells that have high shock deflection very strong and will not break. This helps to distribute the helmet’s impact force evenly, allowing the Styrofoam layer to do its job better.
Carbon fiber helmets will often have some Kevlar mixed into the weave for strength. Carbon fiber helmets will be made almost entirely of carbon fiber material.
Carbon fiber helmets absorb shocks more effectively than helmets made of less durable materials. This means that they can provide excellent protection against helmet failure or head injury during high-speed motorcycle racing. This is especially important if a carbon fiber helmet is dropped accidentally, as it is more resistant to cracks and scratches.
Kevlar
The helmet warehouse created Kevlar to describe a composite material made with an are the mid type of fiber weave base. This material is produced using the same weave processes as fiberglass, then mixed in a very strong plastic substance. For increased tensile strength, carbon fiber helmets often have Kevlar added.
Kevlar’s molecular structure naturally forms in parallel lines. This gives it a much greater tensile load than fiberglass. Kevlar’s strength is so great that bulletproof vests are made from it. Kevlar’s added strength allows the weaves to be lighter, allowing for helmet weights as low as 20% compared to fiberglass.
Kevlar materials have high strength but are not strong enough to withstand compression. To overcome this problem carbon fiber is commonly added to the weave.
Synthetic Reinforced Shell
Synthetic Reinforced shell (SRS), helmets consist of a heat-cured thermoplastic rubber resin, and multiple layers of organic fibers and glass fibers. The result is a helmet shell lighter in weight and with better elasticity under impact than a standard-type thermoplastic resin helmet.
No matter, Shoei Helmets are expensive but it gives more comfort to you. Shoei word means “premium” so it is a better quality product.
