Fiber Weaving Strengthens Turbine Blades

[No.1]

Teledyne Scientific researchers have come up with a method of weaving composite turbine blade fibers that increases through-thickness strength. Currently, multiple fiber layer layups are used, which does not allow for optimal, thin blade trailing edges. The weave technique positions fibers in a 3D arrangement (permitting hollow blades for cooling) and avoids delamination failures.

Amazing what can be accomplished with these composites!

Only problem is their life time, not more then 15 years.
