Roving & Tape Processing

Research goal is the new and further development of the manufacturing processes winding, tape laying and 3D-printing with continuous fiber-reinforced thermoset and thermoplastic matrices including tool and process technology.

Research interests include 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.
