Abstract: Among other things, the present invention provides a system and method for improved infusion of a fiber containing preform with a resin. The system comprises a mould base portion adapted to support the preform and a mould closure portion adapted to overlie the mould base portion in sealable relation to define a mould chamber containing the preform. One or more sensors are attached to the mould base portion and/or to the mould closure portion for monitoring flow characteristics of the resin within the mould chamber. A control means responsive to the sensing means is operatively connected to a resin pump and to a vacuum pump for varying the flow of resin within the mould chamber by varying either or both of the volumetric flow rate of the resin and the level of vacuum within the mould chamber to control infusion of the preform.
