The focus of IRD A is on large-scale processes for the in-line combination of textiles, plastics and
metals. The sensor and actuator integration, as well as the implementation of self-healing elements via
modular processing steps, complete the research programme and the entire manufacturing route. The
investigations are aimed at add-on technologies for the merged manufacturing of semi-finished products
and preforms, which will be applied in the IRDs B, C and D. The emphasis is placed on the manufacture of
multidirectional thermoplastic prepregs with direct impregnation and bionically arranged reinforcement
structures in the tape-laying process. Furthermore, pure polymeric sheets with a defined property
profile for hybrid structures will be used. The minimisation of handling and logistics expenditure in
hybrid semi-finished products, and the simultaneous reduction of process steps in order to decrease
energy consumption and costs by means of process integration, are the most important drivers. This
productivity gap will be closed through the development of an extended fibre-foil-tape unit (FFTU) and a
new continuous orbital wrapping (COW) unit. Both units are intended for the manufacture of tailored
multi-axial hybrid composites and structures with a defined combination of metallic, polymeric and
textile components, with or without functionalisation.
