The invention relates to a method for producing fiber composite shaped parts, especially hollow profile parts, out of fiber reinforced synthetic resin. The shaped parts are stacked in a plurality of layers with fiber matting (prepregs) which is preimpregnated with thermosetting synthetic resin and which is covered with a separating film on at least on one side. The layer body which is formed in such a manner is optionally subjected to a first temperature treatment in a shaping tool. In doing this, the layer body is cooled to a temperature at which the water parts contained in the prepregs freeze and, as a result, the prepegs are no longer sticky. The separating films are then removed and afterwards, while the layer body is still cooled at a temperature at which the water parts contained in the prepregs are still frozen, pressure is exerted on a surface of the layer body in a shaping tool, and the other surface of the same layer body is pressed against the inner wall of the shaping tool. While maintaining the pressure, the synthetic resin is hardened during a second temperature treatment at an increased temperature. |
