GE took a leap forward with the GE-90 that no other manufacturer would do. The risk of carbon fiber on a fan is significant. Typically, it doesn't have anywhere near the impact resistance of titanium. However, the compelling weight benefits on such a large engine were irresistible for GE and resulted in reduced weight for the entire supporting front end of the engine. With an engine that has a weight of about 17,000 lb.........every lb. is important.

To date, there have been no GE-90 fan "incidents" that I'm aware of.........a tribute to GE's design and rigorous testing.
