The group of Carbon composite researches sustainable, green thermosets for high-performance applications with state-of-the-art novel green thermosets based on biogenic materials. Located at the Chair of Carbon Composites, TUM School of Engineering and Design, Technical University of Munich, we offer a motivating research environment in a multidisciplinary laboratory in one of the highest-ranked universities in Europe.

Ph.D., Sustainable thermoset based on biogenic material for a facile recyclable green composite system for high-performance applications

13.03.2023, Wissenschaftliches Personal

A fundamental transition is required from fossil-based polymers to renewable resources and alter the concept of one-time use to continuously up-cycle, down-cycle or recycle polymeric materials. Most of the plastics that are recycled currently go through mechanical and thermal processing to re-make other plastic products, e.g., thermoplastics such as PE, PP, and PET. Thermosetting plastics and resins cannot be easily chemically or mechanically recycled. The recycling scheme for those structures is always challenging having negative economic and environmental impacts.

In this project, the focus is on the design and synthesis of novel thermosetting polymers that facile recycling, including smart new monomers that can bond and de-bond on demand, using energy-efficient processes such as reverse bonding and de-bonding. The key is the incorporation of suitable degradable functional groups or smart monomers into the polymers in their design stage,” design for recycling’’. The research will include the design and synthesis of new monomers including the use of bio-based raw materials, preparation of high-performance thermosets and investigating its structure-property relationships, chemical de-bonding, separation and recovery of building blocks, and proof of concept for “closed-loop” recycling. The novel polymer will be based on poly furfuryl alcohol (PFA), cured PFA has excellent chemical resistance and fire retardant properties making it effective for long-term applications demanding high performance and heat resistance. Compared to other common resins, this highly stable resin offers a significant improvement in the carbon storage potential for green composites when used as a matrix. Furthermore, the research effort will be also directed towards the development of novel green recyclable composite systems with the desirable performance which can be recycled using chemical de-polymerization of the matrix and recovering the valuable fibers intact. The research activities will include understanding the performance profile, and matrix fiber surface interface of the new thermoset fiber reinforced composite, and characterizing the structure-property relationships utilizing various chemical, structural, rheological, mechanical, and surface characterization techniques.
