In addition to the issues of size, brand, and color, we often pay more attention to the material of the motorcycle helmet.
The general helmet shell is divided into four materials.
1.ABS resin is one of the five major synthetic resins, which is excellent in impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It also has the characteristics of easy processing, stable product size, good surface gloss, etc. Packing and coloring.
2.Composite materials are materials that have new properties by macroscopically, by two or more different materials, by physical or chemical methods.
3.FRP, also known as GRP, is fiber reinforced plastic. It generally refers to the use of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. It has nothing to do with steel. A reinforced plastic made of glass fiber or its products as a reinforcing material, called glass fiber reinforced plastic, or glass fiber reinforced plastic. Light and hard, non-conductive, high mechanical strength, low recycling, corrosion resistance.
4.Carbon fiber, as its name implies, is not only the inherent intrinsic property of carbon materials, but also the soft processability of textile fibers. It is a new generation of reinforcing fibers. Light weight, impact resistance, the best in the motorcycle helmet is carbon fiber. However, in the purchase, although we all know that the best weight of carbon fiber material is the lightest, it is because it is good, so the price is not cheap. However, even if it is made of carbon fiber, the weight of the motorcycle helmet will be controlled at around 1250g, because if the motorcycle helmet is too light, it will be affected by the airflow during high-speed driving, and the motorcycle helmet will be lifted up. At this time, the chin strap will be pulled. Living in your neck, I don't think it is comfortable to ride a bike like this.
