Phase-Changing Morphing Metamaterial with Hieararchical Musco-Skeletal Structure

Abstract

Bio-inspired morphing air vehicles have the potential to provide superior system capabilities by performing multi-scale shape reconfigurations. Biological systems are often formed with materials/mechanisms that allow them to adapt their body shape at the micro- or macro-scale in response to continuously monitored environmental parameters or to achieve desired functions. This inspired the current work. This grant explored design and multi-physics modeling of a multi-stable muscular carbon fiber composite plate and a 3D muscular composite material to achieve macro, global shape change. It also developed self-activated muscular piezoelectric "pixels" material that achieved localized shape change and tuning through resonate frequency modulation. This grant also produced a prototype and concept demonstrator. Multiple papers were published and well-received conference talks were given.
