Materials & Construction
• Standard: Outer layer 3K carbon twill weave or forged carbon pattern; inner layers unidirectional carbon prepreg
• Optional: All-unidirectional carbon construction with colored paint finish (red, blue, white, gray, etc.)
• Backplate: Carbon fiber (standard) or aluminum alloy (optional)
Key Advantages
• Lightweight with high strength
• Excellent rigidity – no deformation at high RPM
• Superior impact and fatigue resistance
Customization Services
• Pre-cut propeller blade slots to customer specification (provide slot dimensions or propeller model)
• Custom design and tooling from customer 3D files or samples
• Options for backplate material, surface color, and wall thickness
For special sizes or designs, please send your drawings. We will provide a quotation and production schedule promptly.
