It is difficult to become the mainstream carbon fiber car debut Wuhan Auto Show


At the 2013 China International Commercial Vehicles Show that has already closed, domestic brands do not all appear, but it does not mean there are no bright spots in domestic cars. At the CIMC booth, the trailer was an absolute protagonist, but the low-profile parked side of the Guangqi Hino 8x4 van was the biggest highlight of the CIMC booth. It wasn’t the vehicle itself that was worth looking at. Its cabin uses a full carbon fiber material. You did not misunderstand, the entire carbon fiber, the material that was previously used in the automotive industry for sports car exterior coverings and upholstery, first appeared in domestic trucks.


The first thing to explain is what is called carbon fiber. Carbon fiber is a kind of high-temperature fiber with high strength and modulus, which is a high-end type of chemical fiber. General use of polyacrylonitrile, viscose fiber and other raw materials, the first pre-oxidation in the air 200-300 °C, followed by inert gas protection with a high temperature of about 1000 °C to complete carbonization, and finally heated to 1500-3000 °C into carbon fiber, Because carbon fiber is light and hard, it is widely used.

From the vehicle's introduction card, it can be clearly seen that the vehicle model is a concept car, indicating that this is a product specially built for participation in the auto show and has not been put on the market. The chassis uses GAC Hino 8x4 truck chassis, Shanghai Hino P11C engine, output power of 352 horsepower. The black carbon fiber compartment is not conspicuous, but according to reports, the weight of the 9650x2550x2860mm cabin is only 1.6 tons, which is 1 ton less than that of the existing compound car body on the market.

Due to the thin body of carbon fiber material, the internal volume reached 64.6 cubic meters, and the optimized drag coefficient of the car body was reduced from 0.8 to 0.61, which can save a certain amount of fuel consumption.

In addition to the carbon fiber body itself, the interior of the carriage also has something to do with it. CIMC introduced the most common cargo fastening load on European trailers into the interior of this carbon fiber car cabin, and the goods can be effectively protected by tying up tight cords. In addition, the goods layering system can be customized according to the needs of customers, effectively utilizing the space in the car and increasing the loading rate.

The hydraulic tailgate adopts Kai Zhuoli's split tail plate. The most important feature of this tail plate is that the rear door of the carriage is a part of the tail plate. Through the operation, the rear door can be completely lowered to load and unload the goods, thus improving the efficiency.

Disadvantages: Expensive, not yet in production

Although there are so many advantages mentioned above, the disadvantage of carbon fiber material is obvious: price. Although the price of the car has not been announced at the auto show, the high price of carbon fiber materials is no longer acceptable to ordinary consumers. In addition, although the strength of carbon fiber is high, once it is damaged, it cannot be repaired and can only be replaced. The high purchase cost is also an important factor that the logistics industry cannot popularize at this stage.


Postscript:

In European countries represented by efficient logistics operations, the main material of van trucks is composite panels. After all, carbon fiber is too expensive for ordinary car owners to accept, and the lightweight design of the vehicle chassis can also reduce the weight of the vehicle. So now it seems that for a long time in the future, the carbon fiber cars on display at this time will not be the mainstream products in the logistics market.

This machine adopts once-through shaping technique, thus has high efficiency and excellent product quality. This machine set has such features as scientific and reasonable structure design, smooth and reliable running and convenient operation and maintenance. Fully absorbs domestic and foreign advanced technology, the reasonable cooling circulation water is to save resources and reduce the production cost. Alloy screw fromChinafamous brand ZhouShan is adopted special mixing function and high plasticizing capacity design, ensure good plasticizing, uniformity color and luster.
