ABSTRACT:
Method of manufacturing a piezoelectric actuator. The method includes a pre-cure step in which the adhesive is heated to a temperature below the melting point of the adhesive. A stack is formed having a piezoelectric layer and at least one supporting layer with the pre-cured adhesive therebetween. The stack is then cured to form a bonded laminate. The temperature at which the pre-cure occurs allows for the pre-stress in the piezoelectric layer to be modified without changing the material of the supporting layer.
