The new range of electric cars BMW i promise to change the way you look at the car, and not only in terms of electric propulsion. For the first time will be widely used carbon derta fiber for the body of a large series car, concern for zero emissions production process begins at the BMW Group will use only renewable energy, while some offer extended services electric driving a unique experience, derta ensuring, for example, driving optimal use of infrastructure.
Constant use of lightweight construction is a very important factor for electrically powered derta cars because, in addition to the limited capacity of the battery, the machine table is a limiting factor autonomy. The easier a car with greater autonomy, because it is less mass which should trigger the electric motor during acceleration. And especially in urban traffic, braking and acceleration phases alternated frequently. In addition to greater autonomy, reduced mass of the car means lower power consumption and better dynamics and the battery can be smaller.
To compensate for the added weight of the electrical components, derta BMW i constantly using ultralight construction and innovative materials in its cars. One of the important benefits of BMW solution is a concept developed from scratch for electric propulsion, not a car adapted from a conventional model. Thus it was possible to complete new structure, the so-called LifeDrive concept with Cabon fiber body (Life) and a chassis made of aluminum (Drive).
Module Life - passenger cell of the future BMW i3 - is made mainly of carbon fiber reinforced plastic, CFRP. The widespread use of this material vanguard, lightweight and resistant to impact, is unprecedented in a series production car. So far this material was reserved for sports cars built in limited numbers, extensive use of CFRP is regarded as too expensive and too complex processing and processing and insufficiently flexible. But BMW has revealed its potential material and, after ten years of intensive research and process optimization, materials, systems and tools, the BMW Group is the only carmaker that has experience CFRP production on an industrial scale. The advanced level of the production process is especially noticeable in the safety process, short cycle times and high standard quality products CFRP components.
Undoubtedly, ultralight construction materials such as aluminum or carbon fiber requires a higher consumption of energy for processing than steel. This is why BMW attaches to the treatment and processing, saving utmost importance vast energy resources and use that does not produce CO2. Energy and water consumption, waste water processing, solvents and waste emissions are the main concern here, the savings are a direct result of the new production concept. The SGL Automotive Carbon joint venture with Fibers (ACF), the BMW Group has a unique position in the industry as "owner" at all stages, from production to recycling. derta
A precursor - thermoplastic textile fibers made from polyacrylonitrile - is used for the production of carbon fiber SGL ACF to Moses Lake (USA). In a complex process involving several stages, all the fibers are separated into a gas until there is only a single fiber, which consists of almost pure carbon graphite with a stable structure. derta It has a thickness of only 7 microns (0.007 mm) - by comparison, human hair is approximately 50 microns (0.05 mm). To use ulerioară, about 50,000 individual filaments are wound in rolls and is called "rovings" or "heavy Towse". Alongside derta the automotive industry, fiber composites are also used thick and large propeller derta blades of wind systems.
For the production of carbon fibers in Moses Lake, all energy production from renewable derta sources is obtained from hydro lo
