Find jobs that fit your situation.

From polymer to bio-fibre composites and back.

Job description

The position aims to contribute to our on-going activities within the COMPOCYCLE consortium, financed by the TopSectorEnergy program including several industrial partners, research institutes and academic partners. In the project we aim to develop 100% biobased, thermosetting fibre composites that are both recyclable and immediately deployable.

You will work on the development of natural-long fibre composites with recyclable and dynamic (vitrimer) polyester resins. Your research focuses on the processing and recyclability of these composite materials, including investigation of the curing behaviour, impregnation, and chemical/physical ageing impact on recycling and reprocessing using various manufacturing routes. Through processing experiments you will explore small-scale composite production and chemical recycling, analyse the resulting microstructure and its efffects on mechanical properties, and link processing parameters to performance and circularity. The work will be carried out at the Aerospace Structures and Materials department labs including the Delft TapeLab, polymer processing and advanced characterization labs at the Faculty of Aerospace Engineering and in close collaboration with academic and industrial partners. 

Job requirements

You have a PhD in with significant knowledge on relevant components such as Composite/Processing Engineering, Chemical Engineering, and Polymer Technology and Processing. Knowledge on dynamic polymers and recycling is highly welcome. You have experience with experimental research, preferably involving natural-fibre or thermoset/thermoplastic composites, vitrimer and other dynamic polymer chemistries, or curing and rheological characterisation. Knowledge of chemical recycling, resin degradation mechanisms, or microstructural analysis (e.g. microscopy, DSC, DMA, FTIR) is an advantage. You have demonstrated capabilities in scientific and report writing as well as oral communication.

You are curious, interested in underlying science, self-motivated, and able to work independently as well as in a multidisciplinary team. You have excellent communication skills in English and enjoy connecting with both academic and industrial partners.

Faculty Aerospace Engineering

The Faculty of Aerospace Engineering at Delft University of Technology is a leading international community where innovation in aerospace meets global challenges. Our support and scientific staff, including PhD candidates, postdocs, and students, largely work together on three main themes: the energy transition, sustainable aerospace, and safety and security, with the aim of tackling climate change and contributing to the independence and security of Europe.

When you join us, you become part of a diverse, collaborative, and forward-thinking environment where your ideas and perspectives are valued. Our work extends beyond the lab—into field labs, innovation hubs, and partnerships with other faculties, research institutes, governments, and industry, both locally and globally.

We are committed to fostering an inclusive and welcoming workplace, assisted by an active Diversity & Inclusion team. This includes tangible support such as funding for extra personnel for family and caregiving responsibilities, mentoring programmes, and initiatives that promote cultural exchange and integration.

You don’t just join our faculty — you join a community where you can thrive, grow, and help shape the future of aerospace.
