Verfahren und Vorrichtung zur Herstellung von faserverstärkten Bauteilen mittels eines Injektionsverfahrens

摘要

The invention relates to a method and device for producing fiber-reinforced plastic components made of dry semi-finished fiber-reinforced products by an injection method for injecting matrix material. The semi-finished fiber-reinforced product (1) is placed on a tool (3), a first cavity (10) is formed by means of a membrane (7) that is permeable to gas and impermeable to the matrix material, said cavity surrounding the semi-finished products (1), and then forming a second cavity (27) between the first cavity and the ambience by means of a film (19) that is permeable to gas and impermeable to the matrix material. Air is extracted from the second cavity (27), thereby transporting the matrix material from a reservoir to the evacuated first cavity (10).
