The primary purposes of metal edge wrapping for carbon fiber propellers are as follows:

1. Enhance structural strength and stability

Enhancing Edge Strength: While carbon fiber offers high strength, its edges are relatively fragile. Metal edge wrapping provides protection to the propeller's edges, preventing damage or cracking caused by stress concentration from impacts, vibrations, or high-speed rotation during operation. This extends the propeller's service life.

2. Enhance Overall Structure: Metals possess high toughness and rigidity, which, when combined with carbon fiber, can improve the structural performance of the propeller. During high-speed operation, the metal edge wrapping assists the carbon fiber in withstanding complex external forces such as centrifugal force, ensuring the propeller maintains a stable shape and structure while guaranteeing its proper functioning.
