Development and Applications of Nondestructive Methods for Predicting Mechanical Properties of Advanced Reinforced Nonmetallic Composites

摘要

A detailed evaluation of the interval velocity, one side access technique was conducted and results indicate that it has, at its present stage of development, a limited usefulness for routinely measuring relative values of polar velocity, and hence polar modulus, for many fiber reinforced composites including boron/epoxy. Although the usefulness of nondestructive modulus measurements for predicting these studies strongly indicate that this capability can be extended to include all fiber configurations at any polar orientation.
