Damage Tolerance and Durability of Structural Power Composites
Abstract
This joint proposal between Imperial College London, Chalmers and KTH Universities to investigate truly multifunctional materials: structural power composites in which the constituents both carry structural load and store/deliver electrical power. The overarching goal is to understand the mechanical damage, degradation and rapid discharge processes in these materials, and hence develop strategies to mitigate any critical failure modes. Despite considerable success in developing proof-of-concepts and advancing electrical performance, here we will focus on the fundamental mechanical damage or failure mechanisms in these materials, particularly as a function of electrochemical charge state. Understanding these interactions will generate new routes to ameliorate the necessary compromises between mechanical and electrical characteristics of the multifunctional composites. Moreover, the intrinsically hierarchical character of the multifunctional architectures may offer opportunities to introduce new toughening, durability and charge dissipation mechanisms.
