Damage Tolerance and Durability of Structural Power Composites
Abstract
The work is focused on realizing carbon fibre based structural battery composites. It has several streams of research. Development of structural battery electrolytes which are ionically conductive and can transfer mechanical loads like the matrix material in a composite. Measurements of the fibre/matrix adhesion using these novel structural battery electrolytes. Modelling of systems level performance using structural batteries. Life cycle analysis (LCA) of structural batteries compared to using monofunctional systems of structural materials and batteries. Introducing a new multifunctional metric to better showcase the advantages of using structural batteries and multifunctional materials in general. We have written a review paper on the current state-of-the-art of structural batteries. We have then used the knowledge and materials developed to make a new type of shape morphing material, which is based on the same fundamental technologies used in a structural battery. Finally, we studied Potassium ion insertion in carbon fibres to investigate if this other ion chemistry is suitable to create multifunctional composites, particularly for energy storage, sensing and morphing. Some more in-depth descriptions of this work is presented below. All-in-all the work has resulted in 8 journal papers and 5 conference papers completely or partly funded by this AFOSR/EOARD grant. It has also contributed to the completion of a Ph.D.-thesis. Some of the work has been done in collaboration with Chalmers University of Technology (Chalmers) with Prof. Leif Asp and his group (2 of the papers), and with Imperial College London (ICL) with Prof. Greenhalgh and his group (1 paper).
