METHOD AND ASSEMBLY FOR INSPECTING A PARTIALLY CURED REPAIR PATCH PRIOR TO INSTALLATION A method and assembly (20) are provided in order to inspect a partially cured repair patch (12) prior to installation. For example, an assembly (20) for inspecting a repair patch 12) is provided that includes a partially cured repair patch (12) comprised of a composite material. The assembly (20) also includes an acoustic facilitation layer (22) disposed proximate of the surface of the repair patch (12) through which ultrasonic signals will be introduced. The assembly further includes a vacuum bag (24) surrounding the repair patch (12) and the acoustic facilitation layer (22). The acoustic facilitation layer (22) has an acoustic impedance that is closer to the respective acoustic impedances of the repair patch (12) and the vacuum bag (24) than the acoustic impedance of air is to the respective acoustic impedances of the repair patch (12) and the vacuum bag (24). i)
