Here’s a detailed comparison between carbon fiber rolled tubes och filament-wound tubes in English, covering manufacturing processes, performance, applications, and more:
Manufacturing Process
| Aspect | Rolled Tubes | Filament-Wound Tubes |
|---|---|---|
| Core Process | Layered wrapping of prepreg or dry fabric around a mandrel, followed by curing. | Automated winding of resin-impregnated fibers onto a mandrel at controlled angles (e.g., 0°, ±45°, 90°), then cured. |
| Automation | Manual or semi-automated, simple setup. | Highly automated, requiring precision equipment for fiber tension and angle control. |
| Fiber Orientation | Limited to axial or hoop directions. | Multi-angle fiber alignment for optimized strength and stiffness. |
| Shape Flexibility | Best for simple cylindrical shapes. | Suitable for complex geometries (e.g., tapered, irregular cross-sections). |
Performance Comparison
| Fastighet | Rolled Tubes | Filament-Wound Tubes |
|---|---|---|
| Mechanical Strength | High axial strength but weak hoop strength; prone to delamination. | Balanced axial/hoop strength; superior compressive/torsional resistance. |
| Anisotropy | Highly anisotropic (direction-dependent). | Reduced anisotropy via multi-angle layering. |
| Weight Efficiency | Moderate (uneven wall thickness). | Excellent (uniform fiber distribution, precise wall thickness control). |
| Fatigue Resistance | Lower (weak interlayer bonding). | High (continuous fibers, strong interlayer adhesion). |
Cost & Production
| Factor | Rolled Tubes | Filament-Wound Tubes |
|---|---|---|
| Equipment Cost | Low (simple tools or manual). | High (specialized winding machines, tension systems). |
| Production Cost | Low for small batches. | High initial cost, but cost-effective for large volumes. |
| Production Speed | Fast (simple curing process). | Slower (precision winding and curing). |
| Scalability | Limited to small-scale production. | Ideal for mass production. |
Tillämpningar
| Field | Rolled Tubes | Filament-Wound Tubes |
|---|---|---|
| Industrial | Decorative parts, lightweight frames, drone arms. | High-pressure tanks, pipelines, robotic arms. |
| Aerospace | Non-load-bearing components (e.g., interior brackets). | Rocket motor casings, aircraft landing gear. |
| Sports Equipment | Low-cost fishing rods, tent poles. | High-end bicycle frames, yacht masts. |
| Energy | — | Hydrogen storage tanks, wind turbine spar tubes. |
Selection Guide
- Choose Rolled Tubes:
- Budget constraints.
- Low-volume customization.
- Non-critical structural applications (e.g., aesthetics, lightweight frames).
- Choose Filament-Wound Tubes:
- High-performance load-bearing applications.
- Complex fiber orientation requirements.
- Mass production with strict quality control.
Custom sizes can be fabricated up to 354″ x 118″ x 2″ thick. Please contact us for more details
