Motorcycle helmet What are the materials?
1. ABS resin materials are common, such as Taiwan's Qimei brand. This is an engineering plastic with strong impact resistance and good dimensional stability. Market price of helmets made of this material: usually the price of full helmets is between 100 and 300.
2. PC+ABS alloy is better than ABS, its strength and toughness have been improved a lot, and its low-temperature impact performance has also been improved a lot. At present, the domestic Austrian energy alloy materials are widely used in helmets.
3. FRP is better than ABS, lighter and stronger, but it is also more difficult to make, and the output is lower, so it is much more expensive than ABS.
4. At present, the best one should be carbon fiber, which is very strong, light, high technical content and expensive!!! (This material can be used as a fishing rod.)
5. PP materials can only be used as toy helmets, and the safety is poor. Never mind.
After understanding the materials, let's see which helmets can be made from these materials?
Full helmet
Provide maximum protection
Minimum wind noise
The best comprehensive protection for face and eyes
Relatively expensive, the weakest sense of the outside world
Relatively heavy, easy to cause neck fatigue
Dual-use helmet
A helmet that combines the advantages of full helmet and cross-country helmet
It can be used on road and off-road
Wide field of vision, goggles can also be used
Longer chin with sun visor, derived from the design of off-road helmet
High wind noise and high wind resistance of sun visor
Open helmet
It is also called four or three helmets. As the name suggests, helmets protect three quarters of the head
Helmets with moderate protection and freedom
Advantages: you can feel the outside world better
Disadvantages: weak face protection in wrestling
Cross-country helmet
The eye opening allows you to wear goggles to prevent dust from entering the eyes. The dust protection of full helmet is insufficient
Longer jaw protects mouth and chin
The sun visor can block the sun when you leap
High wind resistance of sun visor at high speed
Uncover Helmet
The lower jaw can be raised
It can be used as both full helmet and four or three helmets
Suitable for police and commuters, convenient for talking and eating
Half helmet
Cool, light, cheap
Minimum protection area, some local regulations do not allow (USA)
The protection is the lowest. There are many inferior helmets on the market. The protection is quite poor
Helmets still have a lot of knowledge to understand. Every road rider should choose a motorcycle helmet suitable for himself, so as to ensure the maximum safety. There are thousands of roads, and safety is the first!
