- Real-world impact: 40% lighter drive shafts boost power transmission efficiency.
- Enables faster vehicle acceleration and agile bicycle handling.
- Superior Strength & Durability:
- Tensile strength: 8-10× higher than steel.
- Elastic modulus surpasses metals with 50% improved impact resistance.
- 3K twill/plain weave patterns (gloss/matte finish) for visual appeal and structural integrity.
- Operating range: -50°C to 350°C | Anti-UV/chemical corrosion | 15+ year lifespan.
- Precision Engineering Benefits:
- Reduced vibration transmission (e.g., racing suspension/bicycle wheels).
- Aerodynamic optimization (e.g., spoilers/body kits) cuts drag by 15%.
Manufacturing Process & Technology
- Custom Workflow:
- Design phase: Accept 3D models/sample replication (compatible with sports cars, SUVs, road bikes).
- Material layup: Prepreg molding with controlled fiber-to-resin ratio (1:0.5~5).
- Production:
- CNC machining: ±0.1mm tolerance for complex geometries.
- Autoclave curing: 121°C–177°C heating eliminates air voids and ensures uniform density.
- The quality control is excellent：
- 100% inspection: Vickers hardness ≥1100 HV (third-party certified).
- Destructive testing validates fatigue resistance under extreme loads.
Product Details
Precision Engineered for Extreme Applications
Material Science Excellence
We use T700-grade 3K twill-weave carbon fiber, which offers a tensile strength of at least 3400 MPa and an elastic modulus of 240 GPa or higher. To achieve precise fiber-resin ratios—ranging from 1:0.5 to 1:5—we apply prepreg molding technology. This approach ensures the structure remains stable even under extreme loads. Versus metal parts, achieve 40% weight reduction + 50% impact resistance boost – ideal for racing drive shafts, automotive spoilers, and bicycle frames
