Motorcycle helmet manufacturer Said that the motorcycle helmet looks simple, but there are some independent component designs in the gorgeous shell. These components work together to protect your head from accidents. Modern motorcycle helmets are far from beautiful shells glued to foam. It is a complex and multi-level technical system. The enclosure is the first line of defense to absorb and disperse impact energy. The two main structures are glass fiber and polycarbonate. More specifically, the glass fiber shell can be made of any fiber reinforced material, including glass fiber and carbon fiber. Different materials are constructed in different order to produce thin and hard shells. In these cases, the shell can be made thicker or thinner by increasing or reducing the number of layers of material.

The composite shell is high-density, which is why cheap helmets are made of peelable polycarbonate plastic. The enclosure can usually withstand a small impact, such as falling off the seat when parking, without affecting your protection. Small bumps or scratches will not affect it. Anything more serious than a small bump will cause invisible damage, so send the helmet back to the factory for inspection, and then trust it. Any sufficiently strong impact will terminate the service life of the helmet.
