Objectices

• Profiles with a grading of the matrix and fibre architecture as well as adapted edge zone characteristics


• Further development and control of an extrusion-based pultrusion process


• Understanding of the process, in particular the elementary mechanisms (e.g. filtration effects)


• Investigation of subsequent processing of the profiles through thermal modification


• Basis for hybrid components with optimum load transfer at the transition zone

Scientific questions

• Which is the appropriate design of the pultrusion process to produce profiles with dedicated edge zones?


• What are suitable infiltration masses which fulfil the requirements of the pultrusion and the thermal modification process?


• How are the elementary mechanisms influenced during the production processes?


• How can the pultrusion process be simulated and controlled for an optimal transition area between the substructures?

Work programme and methods

• Research of the infiltration mass by means of compounding


• Discontinuous model experiments to clarify the mechanisms of action


• Mould design, pultrusion with material and parameter variation (DoE) and additional static and dynamic simulation


• Thermal modification process and structure and property characterisation
