Long and large-diameter CFRP pipes via sheet winding
Sheet-winding (SW) production of long-length and large-diameter CFRP pipes using UD prepreg, enabling hybrid pitch/PAN fiber designs for high strength and precision.
Problem solved
Metal or filament-wound pipes are heavy, corrosion-prone or limited in length/diameter; buyers need lightweight, high-precision tubular structures for industrial rotating or structural uses.
Application contexts
- industrial rollers and shafts
- automotive propeller shafts
- aerospace tubular structures
- precision machinery components
Technical principle
Layering unidirectional prepreg sheets on mandrel with controlled orientation, followed by curing; allows precise control of fiber angles and hybrid fiber use for optimized axial/bending performance.
Typical use cases
- Lightweight high-precision industrial drive shafts
- Large-diameter corrosion-free rollers
- Hybrid-fiber propeller shafts for racing vehicles
