Motorcycle helmetWhat are the materials？
1. ABS resin materials are common, such as chi mei brand in Taiwan.This is an engineering plastic with strong impact resistance and good dimensional stability.The market value of this material helmet: the helmet is usually between 100 and 300.
2.PC+ABS alloy material is better than ABS, with much improved strength and toughness, and much improved impact performance at low temperature.At present, it is widely used in helmets in China.
3.Fiberglass is better than ABS, lighter and stronger, but it's also harder to make, and the yield is lower, so it's more expensive than ABS.
4.At present the best should be carbon fiber, very strong, very light, high technology content, very expensive!!!This material can be used as a fishing pole.
5.PP material can only be made of toy helmets, the safety is very poor.Don't worry about it.
So now that we have the materials, let's look at what these materials can be combined into what kind of helmet can we make?
Provide maximum protection
The wind noise minimum
Comprehensive protection of face and eyes is the best
More expensive, the weakest sense of the outside world
Relatively heavy, easy to cause neck fatigue
A helmet that combines the advantages of the full and off-road helmets
Road cross - country can be used
Wide field of vision, also can use goggles
A longer jaw with a sun visor, derived from the off-road helmet design
Wind noise is larger, the sun visor wind resistance is larger
Also known as the four or three helmets, as the name suggests, helmets protect three quarters of the head.
A helmet with adequate protection and freedom
Advantage: let you can better feel the outside world
Cons: wrestling face protection is weak
Eye openings that allow you to wear goggles to protect your eyes from dust, full helmets, etc
A longer jaw protects the mouth and chin
The sun visor blocks the sun as you fly
At high speed, the wind resistance of the sun visor is large
Jie face helmet
The lower jaw can be raised
It can be a full helmet or a four or three helmet
Suitable for police and commuters, easy to talk and eat
Cool, light and cheap
Minimum protective area, some local regulations do not allow (USA)
Minimum protection, there are a lot of inferior helmets on the market, very poor protection
Helmets still have a lot of knowledge to understand, every road cyclist should choose their own motorcycle helmet, so as to ensure the maximum safety, thousands of roads, safety first!
