yeah, that's because the people buying those cars have more money than they know what to do with and they can get away with it. lol
I know a guy with a race car that has Carbon Fiber rotors. They were expensive but not 14k... maybe half of that.
Not carbon fiber...Carbon-Carbon Composite. Similar, but way better!!
What is Carbon-Carbon?
The first stages in the production of C/C is similar to that in the production of carbon fiber reinforced phenolic. Subsequent processing usually invokes one or two routes.
In the first route, commonly referred to as LPI, (liquid phenolic impregnation), the phenolic resin composite is heated to high temperatures in the absence of air. This process is known as carbonization and results in the formation of a carbon char. The resultant porous media is then infiltrated with more phenolic resin and further carbonized. This cycle is repeated until a specific carbon content is reached. This is usually measured by the density and, in the case of LPI, C/C is in the range of 1.5 to 1.6 g/cc.
In the second route to C/C commonly referred to as CVI (chemical vapor infiltration), the phenolic resin composites is first carbonized at temperatures up to 2,500° C (4,500° F) to create a porous structure. It is then subjected to the chemical vapor infiltration process. In this step a hydrocarbon gas (natural gas or mixtures of methane and other gases) is “cracked“ at about 1000° C. The resulting carbon is deposited in the porous carbon fiber structure. Although this process is much longer than the LPI route, mechanically superior materials can be made!
Carbon/Carbon has a unique balance of properties. The high temperature capability coupled with its high friction behavior makes it the choice for aircraft and racing car brakes. (Other structural applications rely on its ability to retain high levels of strength at temperature. Specific varieties of C/C exhibit very high levels of thermal conductivity. This coupled with its low coefficient of thermal expansion make it ideal for spacecraft heat exchangers, for example.
