Separation of Hybrid Structures for the Reclaim of their Single Components

S. Schweizer, A. Becker-Staines, T. Tröster, Key Engineering Materials (2017), pp. 568-575

<jats:p>The main objective for an economic and ecological use of raw materials is the achievement of closed raw material cycles. Because of that, not only the manufacturing procedures are important during the development of new materials but also the recycling processes. Within the increased use of lightweight construction in recent years, the application of multi-material or hybrid structures reach high significance for the automotive industry. In this development, especially the carbon fibre reinforced plastics (CFRP) gained its importance. However, currently there are no recycling strategies available for hybrid structures; complete recycling processes for CFRP are still expandable. This work presents methods for separation of hybrid structures made of metal and CFRP, as well as the corresponding process windows and the boundary conditions. The separation is performed by introduction of thermal heat and the behaviour of these bonded compounds is analyzed based on shear tensile tests. The results of these studies are used to develop a complete recycling process for reclamation of hybrid structures.</jats:p>

    <jats:p>This publication describes new process chain approaches for the manufacturing of intrinsic hybrid composites for lightweight structures. The introduced process chains show a variety of different part and sample types, like insert technology for fastening of hollow hybrid shafts and profiles.

The derived process chains base on automated fiber placement, resin transfer molding, deep drawing, rotational molding and integral tube blow molding.</jats:p>

      Novel Process Approach for in-situ Insertion of Functional Elements in RTM-Applications

      M. Bobbert, F. Augethaler, Z. Wang, T. Tröster, G. Meschut, Journal of Materials Science Research (2016)

      <jats:p>Lightweight design in vehicles leads to an increasing use of fibre-reinforced-plastics (FRP). To ensure the possibility of detachable joints in those constructions specific joining technologies have to be developed. Available technologies are not suitable for mass production or are leading to damage in the FRP. The aim of this paper is to show the possibilities and the general feasibility of a new process approach for the application of functional elements in FRP or hybrid materials during resin transfer moulding (RTM) processes. Therefore the movement of the RTM-tool-punch is utilised to produce an interlock between the splay stud and the fibres of the non-consolidated preform. This enables the application of the elements during the RTM-process. The resin infusion leads to the consolidation of the CFRP and a further fixation of the splay stud. Pull-out-tests as well as torsion tests are showing the mechanical performance of the joints.</jats:p>

        Z. Wang, M. Riemer, S.F. Koch, D. Barfuss, R. Grützner, F. Augenthaler, J. Schwennen, Advanced Materials Research (2016), pp. 247-254

        <jats:p>The increasing use of hybrid materials requires efficient manufacturing processes. With the concept of the intrinsic hybrids the shaping or forming of the part is combined with the hybridization in the same process step and thereby the same tool. Hence new tooling concepts, which realise the process requirements, are necessary. This paper describes tooling concepts and design methods for the manufacturing of intrinsic hybrid parts. Different solutions for rotational and planar parts with thermosetting or thermoplastic matrix material are presented. Additionally the integration of inserts in such tools is discussed. Finally the main challenges for the design of tools for intrinsic hybrids will be presented.</jats:p>
