The process includes placing in a mold a pile of plies taken from a web of fibers
embedded in a thermosetting or thermoplastic material, the plies being arranged
according to preferred directions of the fibers, and subjecting the mold to particular
pressure and temperature conditions. The process also includes carrying out successive
operations of shaping the pile of plies in the mold, at low pressure, carried out
progressively at low speed; removing the material in excess protruding out of edge
of the mold; carrying out the tightness of the mold from outside; increasing the
pressure up to high pressure; raising the temperature of the mold; and quickly
cooling the mold.
