Shape-morphing carbon fiber composite using electrochemical actuation
Abstract
Structures that can change their shape are advantageous in a wide variety of applications such as aerospace, renewables, and robotics. The problem with current shape-changing technologies is that they are either heavy, lack mechanical stiffness, or are hard to control. This paper demonstrates a shape-changing carbon fiber composite material, which is lightweight, has a stiffness higher than aluminum, and is electrically controlled. Future applications for this material could include trimming of aerodynamic surfaces for steady-state conditions in aircraft and wind turbines, and deployment of satellite booms.
