Motor racing team safety helmets require firmness, light weight, fire resistance, heat insulation, etc., so the helmets are made of light and high-strength materials through multi-layer pressing.

Usually, racing helmets are divided into full-face helmet and half-face helmet, with goggles in front, and the package protection is more careful. Regardless of the structural form, its heat dissipation and sweat-conducting function is a problem worth considering. At present, some helmets have ventilation holes in different parts due to consideration of the driver's breathing and heat dissipation needs. Filters are generally installed in the ventilation holes to prevent foreign objects from entering. But with only a few ventilation holes, the heat dissipation effect is not ideal. During the driving process of the racing car, the driver often sweats and flows into the neck, etc., which greatly interferes with the driving behavior of the driver and affects the performance of the race.
