Summary

The purpose of this project is to determine the feasibility of utilizing ultrasonic techniques to measure mechanical properties of cast polyurethanes. Two suppliers prepared and delivered several series of specimens simulating both binder and propellant materials in various conditions of aging. Ultrasonic examination was performed of these specimen materials with the objective of finding ultrasonic properties which would indicate their physical condition. Results of tests indicate a significant dependence of both shear wave attenuation and relative acoustic impedance of certain specimen materials on their condition of aging. (Author).
