Outline of Final Research Achievements

The effects of reinforcements, layered structures, pre-strain, compliant electrode on electro-mechanical behavior were investigated by both experiments and finite element analysis. The bending deformation can be controlled by the nylon fibers due to their constraining the deformation in fiber axial direction. Moreover, the fibers can increase creep and fatigue life of the dielectric elastomer actuator. It was found that the optimum amount of carbon black powders in the carbon grease is 40% for the electro-mechanical evaluation experiments. The prediction of bending deformation was made by a composite model and finite element method.
