Innovative solutions for controlling shape deviations in the stamp forming of fiber-reinforced plastics

Innovative solutions for controlling shape deviations in the stamp forming of fiber-reinforced plastics

Fraunhofer-ICT
Motivation

Fiber-reinforced plastics offer high strength, rigidity and impact resistance combined with low weight. Due to the increasing scarcity of resources and the need to protect the climate, innovative lightweight construction solutions are becoming increasingly important. Thermoplastic laminates can be heated and formed into complex geometries using a pressing process. Due to the residual stresses that arise in the component during the forming process, the components often exhibit shape deviations compared to the CAD model. One approach to reducing the shape deviation is the defined application of forces after forming.

Project description:

The aim of this Bachelor's thesis is to investigate innovative approaches to reducing shape deviations, in particular by applying forces in a targeted manner immediately after the stamp forming process. First, the formation of shape deviations in connection with the laminate structure is investigated in order to analyze the potential for reduction through defined forces. The theoretical knowledge gained will then be validated on a 3600t press at the Fraunhofer ICT. This investigation will not only contribute to the optimization of component quality, but also to the further development of efficient manufacturing processes in the field of fiber-reinforced plastics.

 

The task will be carried out in close cooperation with the supervising research assistant. You will be supported by our technical staff at all times during the practical activities.

Work content:

  • Carrying out comprehensive research into the definition, development and prevention of shape deviations in thermoplastic materials.
  • Development of a test plan for the selection of suitable laminate structures and the defined force application points
  • Experimental investigation of the components under the defined conditions
  • Evaluation and documentation of the measurement results, taking into account the factors influencing the shape deviation
