Abstract

This paper focuses on the processing and fabrication of carbon nanotube (CNT) based electro-active shape memory epoxy nanocomposites for improvement in mechanical properties and shape recovery behavior. Electro-active shape memory specimens have been fabricated by soaking CNT membranes in shape memory epoxy (SME) through a specialized fabrication process developed in-house. The improvement in dynamic mechanical properties of the baseline SME using CNT membranes is demonstrated using single-cantilever dynamic mechanical test setup and is correlated with the microstructure through scanning electron microscopy characterization. For the CNT-SME, the improvement in storage modulus in the range of 30-90ׄ°C was found to be 60% and 82%, respectively In addition, the electrical actuation of the CNT-SME is demonstrated using a 10V DC supply and the shape recovery response is characterized.
