Composites are becoming the material of choice for many weight-critical applications because of their high specific stiffness and the ability to tailor their properties for special applications. In addition, the composite fabrication process is amenable to the inclusion of embedded treatments, which can be exploited to enhance the structural-acoustic performance. This paper provides a summary of the techniques currently used for acoustically tailoring composite structures with embedded, passive damping techniques. A summary of prediction methods for assessing the treatment performance is also provided. The focus of the paper is on cylindrical shell structures such as pipes.
