3-D woven composites process

The aero-acoustic geometry fan blades, fan case and several other parts of CFM International’s Leap engine series will be the first major engine application of a new technology, 3-D woven composites. The process was pioneered by Albany Engineering Composites (AEC), a U.S. company that has teamed with CFM parent company Snecma and has granted the French engine maker exclusivity for its process (for propulsion applications) for the life of the Leap program.

The NTSB last month sent recommendations to the FAA and Transport Canada to address a safety concern raised by two engine failures on Bombardier CRJ200s. The Board has determined that a flaw during the manufacturing process for fan blades led to the failure of the GE CF34-3B1 turbofans, and it wants procedures established to remove the suspect blades before another incident occurs.
