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 .
