Hello everyone,
I am trying to understand why carbon fiber components in BMW 7 series and many other cars are used in conjunction with Steel? Why are carbon fiber stand-alone components not used instead of these hybrids? Are there any intrinsic problems with stand-alone carbon fiber components?

     I would like to mention, that carbon excellent elastic propertys, but isn't very malleable. Although you can achieve highest energy dissipation with carbon crash elements (f1 monocoque) they have to....

     High costs is really no simple answer. There is much more to it than you might think. And doing it as a hybrid structure isn't always the cheaper way. Carbon crash structures: the basics are pretty....

     A f1 tub and a nose are grey specific in their design that they have to pass 1 set of rules in a very specific crash test and the squeeze tests. Lots of " cheats" that go on 8.1 Ali core used for...
