1. A method for producing a fiber composite component, the method comprising:
- placing at least one textile component preform on a molding tool surface;
covering the at least one textile component preform with an air-tight covering formed from a resin film, which is applied as a covering to the at least one textile component preform in a liquid to semi-liquid state;
adding a catalyst essentially only on a resin film surface facing away from the at least one textile component preform so that outermost surface areas of the resin film are cured or cured more rapidly to create or stabilize a gas-tightness of the resin film;
exerting pressure on the covered at least one textile component preform, in at least one stage of production, by evacuating a vacuum chamber between the molding tool surface and the air-tight covering; and
infiltrating and curing the at least one textile component preform, wherein an identical resin material is used for the infiltration and the resin film.

Abstract
A fiber composite component is made by infiltrating and curing at least one textile component preform that is placed on a molding tool surface and covered with an air-tight covering and on which pressure is exerted, in at least one stage of production, by evacuating a vacuum chamber between the molding tool surface and the air-tight covering. The air-tight covering is formed from a resin film.
