According to the British "Economist" magazine recently reported that held recently in Spain, Valencia F1 Grand Prix had an astonishing scene: Mark Webber's car to the speed of 306 kilometers per hour when a serious rollover accident . Fortunately, Weber himself unscathed.
Weber's "last straw" is very popular in the current F1 racing carbon fiber base. Although iron and aluminum materials, the carbon fiber, "worth" more, but its resistance to stress, and portability is far superior to iron and aluminum. Currently, in many sophisticated areas can see the "nowhere", such as aircraft wings, super cars and expensive mountain biking.
Although carbon fiber has been "flying into the common car home" in many parts on the car, but if BMW's R & D success, then the body made from carbon fiber or electric vehicles will become mainstream.
Early July of this year, BMW announced its long-awaited electric car development program, plans to launch by 2013 plug-in electric vehicles Megacity. The new model does not come from the modification of existing models, but BMW's engineers hardships of a new attempt. The performance of the "no iron" four city car will be more portable, its consists of two parts: the transmission system and battery containing aluminum chassis and mounted on the chassis of carbon fiber cars "skeleton."
Carbon fiber 30% lighter than aluminum, 50% lighter than iron. Moreover, since carbon fiber has a strong tear resistance, when it is woven into the lattice-like structure, and then into the resin, its strength should be more than iron. However, this procedure requires a lot of labor and the efficiency is very low, therefore, the possibility of large-scale production of carbon fiber is not high. However, BMW is trying to change that.
