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.
AI-assisted directory summary. Technical specifications, performance metrics, readiness and compliance labels are unverified unless individually supported and reviewed. Proposed partnership routes do not establish supplier consent, export eligibility, or willingness to sign an NDA. Confirm claims and test conditions with the linked sources and supplier before procurement or citation.
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
