Motorcycle helmet manufacturer Introduction to commonly used raw materials

1. ABS engineering plastics. ABS engineering plastics is PC+ABS, and the Chinese name of chemical industry is plastic alloy. The reason why it is named PC+ABS is that this raw material has excellent heat and weather resistance, dimensional stability and impact resistance of PC resin and excellent processing fluidity of ABS resin. Therefore, it can be used for thin-walled and complex shaped products to maintain its excellent functions and the formability of plastics and esters.

2. Glass fiber reinforced material is a new composite material developed at the beginning of the 20th century. It has the advantages of light weight, high strength, corrosion prevention, heat preservation, insulation, sound insulation, etc. One kind of composite material is fiberglass, which has nothing to do with steel. It is completely free of iron and is not a composite material of glass fiber reinforced plastics. In fact, GRP is a composite material of glass fiber and one or several thermosetting or thermoplastic resins. The resins used include phenolic resin, epoxy resin, polyester resin, polyimide resin, etc.

3. Carbon fiber is a fibrous carbon material. Its strength is higher than steel, its density is lower than aluminum, its corrosion resistance is better than stainless steel, its high temperature resistance is better than heat-resistant steel, and it conducts electricity like copper. It has many valuable new raw materials with electrical, thermal and mechanical functions. The aircraft made of carbon fiber and plastic composite materials is not only light in weight, but also low in power consumption, large in thrust and low in noise; Using carbon fiber to make electronic computer disk can increase the storage capacity and calculation speed of the computer; The use of carbon fiber reinforced plastics to manufacture satellites and rockets for world aircraft has high mechanical strength and light weight, which can save a lot of fuel. Electric vehicle helmet Among the materials of the shell, carbon fiber z is good, and its weight is very light. The technology content is high, but the price is too expensive.
