Abstract

A method and a tool component for forming in an article of fiber-reinforced composite material at least one locally placed, sharply curved portion. A separate, substantially rigid pressure-transferring element configured with a profile corresponding to the at least one curved portion is placed over the laminate at the location of the at least one locally placed, sharply curved portion of the mold surface. A flexible membrane placed over the laminate and over outer, separated surfaces of the pressure-transferring element is evacuated to depress the laminate to fully conform to the shape of the mold surface.
