Abstract
A composite fan blade includes a metal member and a plastic member. The metal member has a binding portion and a plurality of blade portions circumferentially arranged around the binding portion. The plastic member is at least partially secured to the binding portion to form a hub structure. The binding portion includes a substrate and a plurality of connecting plates circumferentially arranged around the substrate. Each connecting plate has an inner surface and an opposite outer surface, with the blade portions protruding from the outer surfaces of the corresponding connecting plates. A notch is formed between any two adjacent connecting plates.
