Abstract:
Fiber reinforced plastics are increasingly employed in the automobile industry. The process chain of resin transfer molding offers one approach for realizing structural components made of fiber reinforced plastic in high quantities. In order to increase economic efficiency, automated solutions for the subpreform assembly are required. There is also the need for mechanically highly stressable and at the same time economical joining techniques for joining fiber reinforced plastics with metal. The following article shall provide an approach to meet both of these requirements.

Abstract:
The production and processing of fiber-reinforced plastics (FRP) is constantly increasing in industry. A commonly used method is resin transfer molding (RTM). FRP components are produced for large series by now. Therefore, the aspect of processing efficiency is becoming more and more important. The semi-finished product can be better exploited, for example, if large preforms were composed of single subpreforms. These subpreforms are easier to drape and can be produced within an automated line. Consequently, the necessary assembly of the subpreforms needs to be automated as well. This way, the process can be made time and resource efficient. The article that follows now will focus more closely on a concept that deals with the handling and subsequent assembling of subpreforms. Furthermore, the variables that can be adjusted for the assembly process are examined and their influence on the resulting connection quality is shown.

Abstract:
Hohe Energiekosten und ein zunehmendes Umweltbewusstsein sowie die immer strengere Gesetzgebung forcieren den Einsatz leichter Werkstoffe zur Energie- und Ressourceneinsparung. Vor diesem Hintergrund gewinnen faserverstärkte Kunststoffe durch das besonders gute Verhältnis von Dichte zu mechanischen Eigenschaften an großer Bedeutung. Ausgangsbasis zur Herstellung dieser verstärkten Werkstoffe sind Faserpreforms*, die in einem nachfolgenden Prozessschritt mit einem Harz-Härter-Gemisch getränkt werden und zum Endbauteil aushärten. Ein vielversprechendes neues Verfahren zum verschnittfreien Endkontur-Preforming ist das Fiber-Injection-Moulding (FIM).

Abstract:
In this paper, a novel pixel-based draping and gripping unit will be presented. To monitor and control the draping during the forming of a stack of semi-finished textiles, the pixels are equipped with integrated sensors. With these sensors, it is possible to adjust the tangential sliding and the normal holding force at each pixel. The sensor principle is based on the electrical conductivity of carbon fibers. Electrodes inside the gripping system allow a conclusion to the gripping force between the gripper and the carbon textile. Therefore, the gripping force can be adjusted to the special boundary conditions during the draping process.

Abstract:
The handling and layup of unidirectionally reinforced thermoset prepreg patches is currently a largely manual process. To reduce labor costs and increase part quality, automated handling of the material is desired. However, laying down the prepreg is challenging due to the tack of some materials. This paper investigates various modifications to an existing vacuum gripping system to enable a reliable separation process between the prepreg and the gripping system. The investigation focuses on the improvement of the integrated pneumatic blow-off mechanism, the development of a mechanical separation system and the application of different suction pads.

Proceedings of the 18th European Conference on Composite Materials (ECCM18), Hrsg. European Society for Composite Materials (ESCM), S. 1-8.
Abstract:
Backing foil or paper needs to be removed from the raw material prior to the processing of Sheet-Moulding-Compound (SMC) or unidirectionally reinforced prepreg (UD-Tapes). In present automated production processes, this step is conducted after unrolling the raw material and prior to the cutting. In a process chain, which is conducted in the authors project, the backing foil needs to remain at the material after the cutting step. For these process chains, a method needs to be found to remove the backing foil from the material. In the state of the art, methods are shown to remove backing paper from prepreg. In this paper new methods are developed and tested for the removal of backing foil together with existing concepts. The main difficulty is the transition from backing paper to backing foil which has a higher tack to the material, is thinner and mechanically less strong. Concepts which are investigated use compressed air, mechanical forces or the stiffness of the foil. The application of compressed air is tested between foil and prepreg. Mechanical forces can either be introduced using grippers, brushes, friction to rubber or adhesive tape. The stiffness of the foil is used when removing it through bending the prepreg.
