Mechanical and Impact Properties of Structural Power Devices
Abstract
This joint proposal between Imperial College London, Chalmers and KTH Universities toinvestigate truly multifunctional materials: structural power composites in which the constituentsboth carry structural load and store/deliver electrical power. The overarching goal is to understandthe mechanical damage, degradation and rapid discharge processes in these materials, and hencedevelop strategies to mitigate any critical failure modes. Despite considerable success indeveloping proof-of-concepts and advancing electrical performance, here we will focus on thefundamental mechanical damage or failure mechanisms in these materials, particularly as afunction of electrochemical charge state. Understanding these interactions will generate new routesto ameliorate the necessary compromises between mechanical and electrical characteristics of themultifunctional composites. Moreover, the intrinsically hierarchical character of themultifunctional architectures may offer opportunities to introduce new toughening, durability andcharge dissipation mechanisms.
