Abstract
The invention proposes a process for bladder moulding thin articles made of a composite material consisting of fibre and polymerised resin, the articles comprising corners having a rounded vertex and produced by a shaper. Such a process is distinguished in that the surface experiencing the air pressure is convex and the normals to the surface converge on the rounded shaping vertex of the shaper.
