1. An apparatus for testing and inspection of a composite-repaired area of a structure, comprising:

  • a signal generator having a test signal output;

    a first transducer attached to the structure and receiving the test signal from the signal generator for converting the test signal to a mechanical signal transmitted through a portion of the composite-repaired area of the structure;

    a second transducer attached to the structure for receiving the mechanical signal transmitted through the structure and converting the received mechanical signal into a response signal varying with the mechanical properties of the composite-repaired area; and

    a signal processor coupled to the second transducer and receiving the response signal to output a display signal indicative of the mechanical properties of the composite-repaired area of the structure, said signal processor comparing the display signal to a baseline reference signal representing the mechanical condition of the composite-repaired area.
