High fiber-volume-fraction CFRP pipes via sheet winding
Custom small-to-medium diameter CFRP pipes and rods produced by sheet winding method achieving high carbon fiber content for strength-to-weight optimization.
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
Need for lightweight, high-strength, corrosion-resistant tubular components in small batches where filament winding equipment is oversized or inflexible.
Application contexts
- industrial rolls
- corrosive fluid handling
- lightweight structural poles
- sports equipment shafts
Technical principle
Sheet winding (SW) of prepreg or resin-impregnated carbon fiber sheets onto mandrel enables higher Vf than standard methods with design freedom for custom lengths and diameters (0.45 mm ID to 80 mm OD).
Typical use cases
- Custom CFRP pipes for chemical plant rollers or antenna masts; high-Vf fishing rods and golf shafts
