【Abstract】 A comprehensive nondestructive testing technology for composites and their components is described. Sonic BondMaster for detecting disbond, unbond, delamination, crushed core and other discontinuities (defects) in composite materials can be applied in manufacturing, maintenance and repair of composites and their structures with good repeatability and reliability. The resonant frequency was found to decrease while system damping increased as the center of the discontinuity was approached. The discontinuities were accurately represented by a model for a vibrating plate which was rigidly clamped at its edges.更多还原
