The light-weight, unbelievably durable LEAP fan.
Carbon fiber is revolutionizing the aviation industry, and CFM is revolutionizing carbon fiber. Or at least one of its applications.
LEAP fan blades are manufactured from carbon fiber composites using a propriety process that weaves the blades in three dimensions on a loom into their final shape. They are then injected with resin and baked in an autoclave. Finally, a titanium leading edge is added for durability.
The result is a light weight, highly durable, virtually maintenance-free fan. The fan, combined with the composite fan case, reduces aircraft weight by 1,000 pounds compared to the same size fan manufactured using all-metal materials. This lower weight, along with state-of-the-art blade aerodynamic design, contributes nearly half of the 15 percent fuel efficiency improvement the LEAP engine will provide.
Another first. Another way CFM gives you more to believe in.
