All of these are true about carbon fiber parts EXCEPT that: damage may not be visible from the front side of the part. repairs may not be allowed by some vehicle makers. they are a combination of fiberglass and carbon fibers. the carbon fiber cloth may be visible on some panels.

they are a combination of fiberglass and carbon fibers.

Explanation:

Carbon fiber is made from organic polymers, which consist of long strings of molecules held together by carbon atoms. About 90% carbon fibers are made  up of polyacrylonitrile (PAN) process whereas very small amount about 10% are manufactured from rayon or the petroleum pitch process. carbon fibers are stronger than fiberglass and very expensive due to usage in many industries.
