Abstract

The main objective of this project is the development of a new passive vibro-acoustic treatment for composite panels and composite aircrafts skins to reduce structure-borne transmission of mechanical vibration and the airborne transmission noise. The strength and the stiffness as well as the damage tolerance of the composite panel should be maintained and the total added mass of the treated component must not be higher than 5 %. Moreover the vibro-acoustic treatment must be compatible with the composite manufacturing process.
