Abstract

In the course of processing and use of modern composites it is desireable to be able to determine estimates of their elastic properties. Elastic property information available during processing could be used to determine the state of cure of a composite. This would make possible feedback control of the cure process, thus helping to insure uniform materials. Knowledge of the elastic properties over time of in-use structures such as aircraft, marine, and rocket motor components would also allow quantitative health monitoring of these critical devices.
