Abstract

A manufacturing technique is developed for embedding piezoelectric material in composite laminates while maintaining the structure strength and piezoelectric effectiveness. An ultrasonic C-scan test is applied to screen out the specimen with possible delamination along the interface of the piezoelectric material and glass fiber layer. It is shown that the problem of electrical insulation and piezoelectric material cracking can be prevented. In addition, tensile and static tests are conducted to validate the manufacturing technique. An analytical model is also presented to predict the natural frequencies and mode shapes of a composite structure with embedded piezoelectric materials, and the predictions are verified by modal testing.
