"Plastic car" can be large-scale production

BMW will launch the BMWi3 pure electric vehicle in the autumn. The greatest feature of this car is, the shell is made of plastic, the chassis is made of aluminum alloy, so than the traditional with the types of car weight 250 - 350 kg. As a new type of composite material, carbon fiber reinforced plastic has the advantages of light weight, high strength, corrosion resistance, anti vibration etc.. But the industry think, the high cost, complex process, so it is only used in the car and a few luxury cars.

Krueger said, BMW is the only company to master the use of carbon fiber reinforced plastics technology in mass production of automobile manufacturers, the application of this technology makes the manufacturing costs 50% lower than it was 10 years ago. At present, BMW has been able to determine freely according to the requirements of carbon fiber reinforced composition, strength and shape of plastic parts. One of the key technology of the technology is fully integrated with the accelerating resin, curing agent and curing time. Usually this process must be in a separate pot internal friction at 24 hours, while the I3 production lines will be shortened to a few minutes. The use of carbon fiber reinforced plastics, automobile passenger compartment to reduce the number of parts required than conventional cars, and no longer use screw welding, replace sb. New adhesive. According to the briefing, a I3 electric cars to use about 10 kilogram of the glue.

About the safety of plastic vehicles, vehicle safety and repair expert Wolfgang Han said, I3 has designed 35 kinds of collision probability, and through the strict safety test. In a collision with the front, our reporter saw a carbon fiber door side of the reinforced plastic module after being hit, like paper like crumpled, but cabin crew was safe and sound. Wolfgang Han said, the car was an imaginary middle speed of 32 miles per hour collision, carbon fiber reinforced plastic module is designed for cellular, the impact force quickly spread to the chassis, protect the cabin crew and vehicle battery safety.
