Abstract
A propeller blade includes a first material and a second material. The first material includes fibers. The second material is different from the first material. The fibers are interspersed through the second material and the fibers are oriented in a same direction within the second material. The propeller blade is anisotropic and includes sections of the fibers.
Claims20
A propeller blade comprising:
- a first material comprising fibers that extend through the propeller blade in a longitudinal direction to form a longitudinal fiber structure or extend along a chord line of a cross-section of the propeller blade;
- and
- a second material different from the first material, wherein the fibers are interspersed through the second material,
- wherein the propeller blade includes multiple sections comprising:
- a first section where the fibers are substantially uniformly oriented between a leading edge and a trailing edge of the propeller blade;
- and
- a second section where a volume fraction of the first material decreases from the leading edge to the trailing edge.
