Product Range
Shengjie offers customizable carbon fiber tubes across three series:
- Standard Series: Diameter 6mm–200mm, wall thickness 0.5mm–10mm (drones, medical devices)
- High Modulus Series (SJ-CF-M60J): Tensile modulus ≥450GPa (satellite arms, robotic systems)
- High-Temperature Series (SJ-CF-HR): Continuous service at 400°C (engine components, industrial piping)
Shengjie’s production leverages prepreg filament winding technology and automated processes to ensure precision:
- Materials: Toray T300/T800 (Japan) and SGL high-modulus fibers (Germany)
- Tolerances: Diameter ±0.05mm, straightness ≤0.1mm/m
- Certifications: ISO 9001, AS9100D (Aerospace), IATF 16949 (Automotive), with third-party fatigue testing (SGS verified, >10⁷ cycles)
- Challenge: Reduce weight without compromising crash resistance
- Solution: T800 carbon fiber tubes (50mm diameter, 3mm wall, 3K twill weave surface)
- Results:
- 55% weight reduction vs aluminum → 8% longer vehicle range
- Passed ECE R100 crash tests
- 12% lower production costs at scale
- Requirement: Ultra-light wing spar (<1.2kg/m) stable across -40°C to 80°C
- Shengjie’s Fix: M60J high-modulus tubes with square profile (25mm×15mm)
- Outcome:
- 200% higher strength-to-weight ratio vs aluminum
- Passed 10,000-hour salt spray test
- 30% faster time-to-market (pre-drilled/coated in-house)
- Issue: Steel arms caused inertia-driven positioning errors
- Collaboration: Carbon fiber-titanium hybrid tubes reduced weight by 62%
- Impact:
- Positioning accuracy improved to ±0.01mm
- Annual maintenance savings: $250,000 (corrosion resistance minimized downtime)
Shengjie provides comprehensive solutions through its R&D centers and global logistics:
- Rapid Prototyping: 7-day lead time for samples (3D files or physical measurements accepted)
- Cost Efficiency: Bulk pricing from $35/m (varies by specifications)
- Global Delivery: 15-day shipping to EU/NA regions, DDP terms available
- Proven Track Record: 1,200+ tons exported globally, 92% customer reorder rate
- Hybrid Customization: Kevlar, fiberglass, or metal-composite integration
- Sustainability: 85% carbon fiber scrap recycled; REACH and RoHS compliant
