Abstract
A method of monitoring a curing process for fiber reinforced composite materials that includes positioning an actuator on uncured composite material at a first location. At least one sensor is positioned at a second location that is spaced apart from the first location. The actuator excites waves in the composite part at the first location. At least one sensor is positioned at a second location that is spaced apart from the first location. The actuator excites waves in the composite part at the first location. The waves propagate through the composite part due to internal reflection. At least one wave metric is measured at the second location utilizing the sensor. At least one parameter of the curing process may be adjusted based, at least in part, on a wave metric measured by the sensor.
