Abstract: Described herein is an apparatus and a method for removing an epoxy resin from a backing sheet at a temperature at or below the glass transition temperature of the epoxy resin. The apparatus (200) comprises a housing (210) in which is mounted a dispensing roll (220) comprising epoxy resin (230) on a backing sheet (240), a wind-up roll (250) comprising the backing sheet (240), a release element (260) over which the backing sheet (240) is directed, and a collection tray (270) for collecting pieces of resin (230a) removed from the backing sheet (240). The dispensing and wind-up rolls (220, 250) are mounted on respective drive shafts (225, 255) which are driven by a drive mechanism (285) controlled by a controller (280). A temperature controller (290) is also provided for controlling the temperature within the housing (210) so that it remains below or at the glass transition temperature of the epoxy resin.
Abstract: The invention concerns a method of molding a part (1?) made from composite material. This method comprises a step of injecting a liquid (7) under pressure into a closed mold (2) containing a fibrous pre-form (1) previously impregnated with resin. Said liquid (7) comes into contact with the resin but it is substantially inert and immiscible with respect thereto. The invention also concerns an apparatus for carrying out this method.
