A composite structure (3) includes a piezoelectric element (1) sandwiched between fiber composite panels (2). The composite structure can be used as an actuator element. In a method for producing the composite structure, the fiber composite panels are pre-stressed and pre-strained by applying respective...http://www.google.com.au/patents/US6162313?utm_source=gb-gplus-sharePatent US6162313 - Method for producing a composite structure including a piezoelectric element
