ABSTRACT:
Structural parts are produced from fiber composite preforms which are placed into a mold conforming to the shape of the desired part. A resin is then injected into the mold so as to fill the mold and encapsulate the fiber preform. The mold is evacuated prior to the injection step, and is rotated about a vertical axis during the injection step. The resin is maintained under pressure during the injection step, and the resin is hardened in the mold whereby net molded parts are formed.
