Abstract: The bicycle helmet is a device to protect the head of the driver and the occupant. The main purpose is to protect the head of the rider when it is impacted, prevent or reduce the injury and even save the life of the rider. The materials used to make bicycle helmets usually include ABS resin materials, alloys of PC and ABS, glass fiber reinforced plastics, and carbon fibers. Among them, carbon fiber helmets have better protective performance. In addition to the material, the qualification standard of the helmet will also affect the safety factor. The bicycle helmet standard includes SNELL standard, national standard, DOT standard and so on. Let's find out what kind of helmet safety is.
What material is good for a bicycle helmet
Bicycle helmet, a device for reducing the occupant in an accident, consists of a shell, a buffer layer, a comfort pad, a wearing device, goggles and other parts. The shell material of a bicycle helmet determines its quality, so what material is a bicycle helmet? ok?
The materials of bicycle helmets are:
1. ABS resin material: This is an engineering plastic. This material is characterized by strong impact resistance and good dimensional stability. The market price of helmets of this material is usually between one hundred and three hundred.
2. PC+ABS alloy material: Compared with ABS resin material, the strength and toughness of this material have been greatly improved, and the low temperature impact performance has also been improved a lot.
3. FRP material: The helmet of this material is made of fiber-reinforced plastic, and FRP is a kind of composite material. FRP helmets are lighter and stronger than ABS helmets, but they are also harder to make and have lower yields, so they are much more expensive than ABS.
4. Carbon fiber material: This material is the best helmet material at present. It is very strong, light and high in technology, but the relative price is relatively expensive. Carbon fiber has high axial strength and modulus, low density, ultra-high temperature, and good fatigue resistance. It not only has the inherent characteristics of carbon materials, but also has the soft processability of textile fibers. It is a new generation of reinforcing fibers.
Note: There are also helmets made of PP material on the market. This material can only be used as a toy helmet, and the safety is very poor.
