At present times thermoplastic textile-reinforced structures are usually processed from semi-finished consolidated parts. Commonly these parts are continuously produced from woven or nonwoven preforms by means of double belt presses. Afterwards the semi-finished parts are tailored, reheated and reshaped by hot compression-moulding. Within the Collaborative Research Centre SFB 639 at TU Dresden a novel process chain is developed, consisting of near-net-shape weaving of spacer preforms from glass/polypropylene hybrid yarns in a single production step and subsequent hot compression-moulding to consolidated sandwich structures. The lecture gives an overview of the technology for weaving spacer performs and of tool kinematics for hot compression-moulding. A second issue of the presentation are simulation techniques to predict the yarn loads in complex weaving processes and to predict processing times in consolidation processes. The lecture concludes with an outlook on applications of the consolidated spacer structures in a demonstrator.

The financial supports from the German Research Foundation (DFG) for the project SFB 639 are greatly appreciated. This paper deals especially with the supported subprojects A3 – “Flat-knitted and woven spacer fabrics from hybrid yarns for composites”, A4 – “Requirements for reproducible production of textile preforms” and D4 – “Textile-adapted processing technologies for plane and simply curved fundamental components with high function integration”. The authors would also like to thank other participating institutes of SFB 639 for the cooperation and the valuable discussions.
