ABSTRACT:
An L-C circuit (tank circuit) is located in close proximity to polymer impregnated composite material layers during the fabrication process. Applicant has determined that the resonant frequency of the tank circuit and the shape of the frequency absorption curve vary as a function of the fiber density of polymer impregnated composite material. The frequency of the input to the tank circuit is periodically swept through a range of frequencies, and the tank circuit impedance is measured to determine the resonant frequency and shape of the frequency absorption curve.
