Method for the manufacture of wind vanes, consisting in: formation of a single foam core (2), with numerical control machines, application of reinforcing layers (3) pre-impregnateted in resin (4), curing of the layers (3) as part of the application process itself, by means of UV (ultraviolet) instant curing and thermal curing, polishing of the vane surface, also by use of an automatic numerical control machine, and final painting. Alternatively, the core is made using a mould, is a single piece or, two shells (2a) and (2b) which are subsequently joined with adhesive, is solid or, at least in the root thereof, hollow, or formed by two solid or lightened shells and can contain a central inner tube (6) of composite as a rigidizing element, and other smaller tubes (7) inside the leading and trailing edges. |
