Back around 2005, I was at the GE Customer Training Center in Evandale (outside Cincinnati) for a meeting. They'd moved the GE history of turbine engine 'museum' there (it had been in the basement of one of the office buildings).
Anyway, there was a display of the GE90-94B, including a claim that there had never been a GE90 composite fan blade that had to be scrapped due to operational damage (bird strike, FOD, etc.). Pretty darned impressive, although I don't know how much longer it lasted (or if it extended to the much different design of the GE90-115B fan blade).
The GEnx-1B (787) and -2B (747-8) fan blades are similarly impressive, although I'm pretty sure the GEnx-2B can't make a similar claim regarding not needed to scrap any blades. There was an incident a few years back on a 747-8 where the outboard engine ingested a snow bank (
) and suffered quite a bit of fan damage.
