A New Approach to Creating Composite Materials Elastic Property Database with Uncertainty Estimation Using a Combination of Mechanical and Thermal Expansion Tests

Abstract

In this paper, we propose a new approach to determining those five elastic constants with uncertainty bounds using the extra information obtainable from an over-determined system. The approach takes advantage of the classical theory of error propagation for which variance formulas were derived to estimate standard deviations of some of our five elastic constants. To illustrate this approach, we apply it to a set of experimental data on PEEK/IM7 unidirectional lamina.
