Short cut carbon fibers have good dispersibility in PEEK resin, which can make the performance of the blade more uniform and stable.
Under dynamic conditions such as high-speed rotation of the blade, short cut carbon fibers can work more flexibly in the matrix, better withstand dynamic stress, and improve the fatigue resistance and flexibility of the blade. There will be no problems such as fatigue fracture due to stress concentration.
Moreover, the paddle reinforced with short cut carbon fibers can effectively reduce vibration and noise and improve the user experience through more uniform stress distribution and moderate flexibility.

Light density ：
Short cut carbon fiber reinforced PEEK material's density is about 1.4g/cm ³, much lower than metal materials such as aluminum alloy's 2.7 g/cm ³. This lightweight feature can significantly reduce the weight of drone paddle, thereby improving flight efficiency, extending endurance, and reducing energy consumption.
High and low temperature resistance:
PEEK material can maintain stable mechanical properties within the temperature range of -60 ° C to 250 ° C. Its melting point is as high as 343 ° C, and its short-term use temperature can reach 300 ° C. PEEK paddle are capable of stable operation in extreme temperature environments, such as high-temperature deserts or low-temperature polar regions, and can adapt to various complex climatic conditions.
High strength:
Carbon fiber has extremely high strength and modulus. When combined with PEEK resin, it can effectively transmit stress and enhance the overall mechanical properties of the material. When subjected to external forces, carbon fiber can bear most of the load, greatly improving the strength and fatigue resistance of unmanned aerial vehicle propellers.
High speed rotation stability:
Drone paddle generate significant centrifugal and aerodynamic loads during high-speed rotation, and PEEK's high strength allows it to withstand these complex stresses without deformation or fracture.
High dimensional stability:
The distribution of short cut carbon fibers in the Peek material is uniform, ensuring the dimensional stability of the Peek blade under complex stress conditions.
Lightweight and low-noise:
Compared with metal materials, PEEK has much higher damping performance. PEEK can effectively absorb and dissipate vibration energy, reducing the propagation of vibration and noise.
