Research Activities

My research activities revolve around the manufacturing and performance of composite parts and structures, with a specialization in thermoplastic composites. I am particularly interested in the influence of the manufacturing process on the performance of the final part. Progress in this field requires a structured two-step approach that is outlined in the figure below. First, we need to understand how the processing history affects the material’s microstructure, in which microstructure is defined broadly and encompasses properties such as void fraction, crystalline morphology and fiber-matrix distribution. Secondly, we need to understand how this microstructure affects the (mechanical) performance on a macro-scale.

The performance of a composite component is determined by its microstructure, which then again strongly depends on the raw materials used and the chosen manufacturing route.

A proper description of the interrelations between process, microstructure and performance requires a sound understanding of the underlying physical mechanisms. I rely on experiments, often combined with simple models, to identify and analyze these mechanisms. Our laboratory is well equipped for this task with access to all relevant processing equipment for (thermoplastic) composites. Moreover, our group has a strong background in the development of special-purpose test setups to analyze material behavior for which no standard procedure exists. Once well understood, the relevant mechanisms are implemented in predictive models for use by the industry in order to optimize either the materials used, the processing route or the design of the final component.

I have worked on several manufacturing processes for thermoplastic composites, including laser-assisted fiber placement, over-injection molding, co-consolidation of metal-composite joints, stamp forming, autoclave consolidation, and welding. Currently, I am working on press forming of fiber-placed blanks, vacuum-bag-only consolidation and co-molding of metal inserts. Moreover, I am also involved in two projects focusing on predictive (long-term) performance of thermoplastic composites.

Teaching Activities

I am currently involved in the following educational activities:

Supervisor for Academic Research Skills, and BSc & MSc Assignments
The assignments are related to ongoing research projects on the manufacturing and performance of composites and typically involve both theoretical and experimental work. Topics can range from heat transfer modelling for induction welding to the design of an experimental setup to characterize the performance of multi-material joints. Feel free to drop by and ask about the possibilities in case you are interested in a challenging research assignment in the field of composite materials.
