Abstract:
1. A method for manufacturing beams of composite material with a J-shaped cross-section, comprising the steps of: providing a curing tooling comprising a bar supported parallel to a table by at least two first rigid supports, providing a beam with a J-shaped cross-section made of uncured composite material, the beam having a bottom flange, a web and an upper flange; arranging the uncured beam on the tooling, positioning the bottom flange of the beam so that the bottom flange faces the table at a distance above the table, and resting the web and the upper flange against two respective sides of the bar, covering the beam to be polymerized with at least one vacuum bag, applying a vacuum to the bag, applying pressure and heat inside an the autoclave to cure the resin in the beam.
