Abstract:

An ultrasonic immersion technique has been developed to inspect the bond between the plastic coating and the propellent charge of a solid propellent rocket motor. Some correlation between acoustic measurements and the peel strength of the bond has been found, although more work must be done to gain some understanding of the mechanisms involved. The technique is best applied to materials having similar acoustic impedances. Author
