How will you contribute?

Hybrid composites combine conventional and renewable fibers and promise increased energy absorption, stiffness and water resistance as well as reduced mass, cost, and carbon footprint. Yet, hybrid composites present technical and environmental challenges during their lifecycle and especially at end-of-life, as they are hard to recycle. In this project the focus lies in using benzoxazine vitrimers as matrix materials for hybrid synthetic/renewable and renewable/renewable fiber composites, not only to achieve high performance but also to explore chemical recyclability and establish levels of textile degradation during such processes. This will be complemented by an exploration of mechanical recycling to realize multi-tiered lifecycle options, with the aim to create fully sustainable, high performance hybrid composites.

In addition to scientific support by recognized experts in the field, the candidate will have access to fully equipped labs for fiber composite preparation and testing at various scales. Their efforts will be aided by state of the art characterization facilities, including relevant spectrometric (FTIR, NMR, XPS, MALDI) and chromatographic (GPC) tools, structural characterization methods (SEM, AFM, microCT), thermal analysis equipment (TGA, DSC, DMA, TMA, etc.), mechanical (quasi-static tensile, flexural, etc.) and physical testing (contact angle). The candidate will prepare and test hybrid composites, characterize fiber-matrix interactions and explore recycling options.
