Jansen, K.M.B. Faculty Industrial Design Engineering Department Design Engineering Date 2013-12-31 Abstract A composite structure consisting of a Shape Memory Polymer (SMP) matrix and three Shape Memory Alloy (SMA) strips was constructed. The SMA strips act as actuators which create forward and backward angle bends of 90 degrees of the composite structure. The function of the polymer matrix was to give the structure enough stiffness. During the morphing stage the polymer was heated locally into rubbery condition to allow shape changes. The new structural shape was fixated by cooling the polymer into the glassy state. Since the exact timing and amount of heating power of both the SMA strips and the SMP matrix was crucial for the functioning of the smart structure, a detailed numerical thermal model was build and validated using thermal imaging. With this validated numerical model the optimum activation conditions were determined. The working principle of the smart composite structure was demonstrated with a small scale prototype.
