HAMDI ALAOUI D´ epartement de Physique FST, Errachidia, Morocco Received August 8, 2003; in final form January 5, 2004 As widely used sensors and actuators, piezoelectric materials have received great at- tention. Development of the smart structures can offer a great deal potential for use in advanced industry. This paper discuss the feasibility and efficiency of shape control of piezolaminated composite in antifouling process. The idea is to design an intelligent structural system that is able to protect itself against the fouling.

Recent progress in the field of composite materials has results in the rise of their industrial applications as prime constituent candidates in high-performance. In many applications, active shape and vibration control are means for obtaining optimal conditions of the smart structures in the several environments. Particularly, in marine environment, after their immersion in sea water, all structures are rapidly covered by a biofouling. As it appears mechanical surface vibrations would be effective to prevent the adhesion of fouling [1]. An efficient technique using piezofilms to induce mechanical vibrations have been reported [2, 3]. This paper discuss the feasibility and efficiency of shape control of piezolaminated composite in antifouling. A model describing the behavior of piezolaminated plate has been Address correspondence to M. Rahmoune, D´ epartement de Physique, FST, Errachidia, Morocco.
