Manufacturing process
A process in which resin-wetted continuous fibre tows are wound onto a rotating mandrel. It is the predominant route for hollow axisymmetric parts such as pressure tanks and pipes.
3 of 3 claims on this page cite at least one registered source. Counts describe how each statement is known, not how likely it is to be true.
Each claim states how it is known and cites its evidence.
Filament winding suits hollow components of circular or oval section such as pipes and tanks; it is the predominant process for axisymmetric products such as compressed-gas storage tanks and pipeline sections and offers speed and cost advantages for struts, axles and drive shafts.
Evidence support: Supported by the cited evidence one source
Evidence: U.S. Department of Energy 2015 Primary authority
Filament winding cannot lay fibres in the axial direction of the part, and it usually needs low-viscosity resins.
Evidence support: Supported by the cited evidence one source
Evidence: U.S. Department of Energy 2015 Primary authority
In filament winding, continuous fibre tows or rovings are passed through a resin bath and wound onto a mandrel, and the resin is then cured to the final shape.
