Abstract

A method for producing an article of composite material. A female molding tool is provided. A form bag is provided. At least one prepreg is placed in the molding tool. A heel shaped hard tool part. A hard tool part is placed at the female tool close to an edge of the laminate being placed in the mold. The form bag is placed in the female tool so that the bag seals towards the heel shaped tool part, in such a way that, at a later air evacuation of the bag, an increased pressure that the bag will apply towards the laminate reaches a radius before the pressure reaches an edge.
