Roving & Tape Processing

This field of competence includes the development of efficient winding and tape laying processes with thermoset and thermoplastic matrices. Research interests include work on quality management, process control and optimization as well as process automation such as in-line direct impregnation, ring winding technology or “out-of-autoclave” techniques via in-situ consolidation. Another research field is the enhancement of additive manufacturing technologies (3D-Printing) with endless fibers in loading direction.
