Core Advantage Analysis
- Ultra-lightweight design for dual improvement in battery life and payload
Using aero-grade PAN-based carbon fiber prepreg with a density of only 1.75g/cm³, 60% lighter than traditional aluminum alloys.
Case: After a logistics drone adopted a carbon fiber fuselage frame, its payload capacity increased from 2kg to 3.5kg, and battery life extended by 22%.
2. High-strength fatigue resistance for complex flight conditions
The strength difference between warp and weft directions is controlled within 5%, and the fatigue resistance to alternating loads is 50% higher than that of fiberglass components.
Test data: Withstood 100,000 vibration cycles (5-200Hz, 10g acceleration) without cracks.
3. Customized structural design for all drone categories
Supports personalized component development for multi-rotor (4/6/8-axis), fixed-wing, and compound-wing aircraft.
Processing capability: Minimum feature size of 0.5mm, surface fitting accuracy of ±0.05mm (suitable for foldable wing designs).
4. Strong environmental tolerance to expand operational boundaries
Surface coated with UV-resistant coating (UV resistance ≥ Grade 8), extending outdoor service life by 3 years.
Salt spray test (ASTM B117) for 1,000 hours without corrosion, suitable for marine environment drone operations.
