Damage Mapping Of Composites With Piezospectroscopic Coatings

Abstract

In composite structures there are many different types of damage with varying effects on mechanical performance. This work explores a revolutionary non-destructive evaluation (NDE) technique to diagnose composite damage with Piezospectroscopic (PS) coatings. Several PS phenomena are shown here which reveal intrinsic damage patterns of a composite coupon. A unique integration of piezospectroscopy and digital image correlation (DIC) enables determination of local mechanical properties. With applied multi-scale damage mechanics, it is shown that this integration produces a degrading elastic modulus map with in-situ mechanical loading. Using a phenomenological approach, the PS coating's properties are studied as a comprehensive damage indicator.
