N2 - The dynamic properties of structures change due to the damages produced during the manufacturing process or operation conditions. This is more critical for structures made of fiber-reinforced composite (FRC) materials owing the fact that they possess more complicated structural components which are under invisible delaminations. If the relationship between the properties and the damage is not known, experimental investigation of the changes can be employed to detect and quantify the damages to some extent. In this paper, the structural response of several FRC components are investigated by using non-contact experimental modal analysis employing Laser Vibrometer. To this end, the components with and without artificial invisible damages are tested to identify the changes in the natural frequencies and mode shapes. The method merits and its limitations are discussed.
