This paper presents a dynamic characterization of a smple plate of a grid stiffened composite material being developed for use in launch vehicle payload fairings. First, experimental modal analysis is performed to identify the plate's global models. THe global modes are used for finite element model correlation and for a sound power radiation study which identifies the dominant radiator modes. Next is a strain transfer study using piezoceramic actuators bonded to the plate surface and to the stiffener ribs. Efforts are focused on the ability to sense and excite the dominant radiator modes using the piezoceramic actuators.
