This paper characterises the properties of bi-stable carbon fibre composites actuated using a macro fibre piezoelectric actuator. An unsupported piezoelectric-laminate combination was evaluated in terms of its blocking force, free displacement and load-displacement characteristics. Linear relationships between blocking force and free displacement with applied voltage were observed when the piezoelectric-laminate combination was actuated in a single stable state. The load-deflection characteristics indicate that significant control of the snap-through force could be achieved with applied voltage. (C) 2007 Elsevier Ltd. All rights reserved.
