In the automotive industry, all vehicles use damping materials, which are usually made of composites, to reduce structure‐borne noise and prevent structural damage. The effectiveness of damping treatments depends upon design factors such as the type of materials being used, environmental terrain and size of the treatment. This chapter provides readers a pathway for modelling, analysis and controlling vibration and noise in any segment of the body shell of a vehicle. It reviews typical composite materials used in the shells and panels of a vehicle, and presents two examples to show the modelling, modal analysis and damping treatment of composite structures used in body panels in the automotive industry. If the structural panels are made of an appropriate composite material with adequate damping coefficient or damping treatment, instead of a conventional metal, the noise and vibration may become tolerable and consequently prevent passenger discomfort as well as structural fatigue.
