Systems and methods are provided for enhanced vacuum bags. One embodiment is a method that includes placing a laminate comprising uncured fiber reinforced polymer onto a mandrel, laying up a vacuum bag, which includes integral ultrasonic transducers within a gas-impermeable layer, atop the laminate, and sealing the vacuum bag to the mandrel. The method also includes drawing a vacuum on the laminate via the vacuum bag, removing gas between the integral ultrasonic transducers and the laminate, and interrogating the laminate with the integral ultrasonic transducers.
