Method for producing a fiber composite component

摘要

A method using a tool for producing a fiber composite component includes a planar fiber lay-up placed on a carrier mold, provided with a stiffening section protruding from the lay-up and pressed between parts of a molding tool. A chamber sealed from the mold is formed by an air-tight film enclosing the tool, the lay-up and the stiffening section. The chamber is connected to a resin supply line and a vacuum line. Resin is aspirated by negative pressure applied to the vacuum line, and the lay-up and the stiffening section are saturated by resin to form the fiber composite component. Air and resin are drawn between the parts of the tool, through the stiffening section and into a suction channel extending in the tool and connected to the vacuum line through a suction opening of the tool, for conducting air and/or resin.

1. A method for producing a fiber composite component, the method comprising the following steps:
placing a planar fiber lay-up on a carrier mold; providing a side of the fiber lay-up facing away from the carrier mold with at least one stiffening section protruding from a longitudinal plane of the fiber lay-up; pressing the fiber lay-up between corresponding tool parts of a molding tool; forming a chamber sealed from the carrier mold using an air-tight film enclosing the molding tool, the fiber lay-up and the at least one stiffening section; connecting the chamber to at least one resin supply line and at least one vacuum line; aspirating resin by applying a negative pressure to the at least one vacuum line and impregnating the fiber lay-up and the stiffening section with resin to form the fiber composite component; aspirating air and resin between the tool parts of the molding tool through the at least one stiffening section into a suction channel extending in the molding tool; connecting the suction channel to the at least one vacuum line through a suction opening of the molding tool in an air-conducting and resin-conducting manner; and providing the vacuum line with a membrane filter being air-permeable and resin-impermeable in a dry state and configured to change over into a substantially air-tight state when impregnated with resin.
