ABSTRACT:
Embodiments of the invention relate to a system and method for non-destructively inspecting a component that is at least partially made of a composite material. In one embodiment, the composite component can be a ceramic matrix composite vane or a liner for a turbine engine. Aspects of the invention involve imaging the component using a magnetic resonance imaging (MRI) apparatus. To enhance the image, the component can be infiltrated with at least one contrast media, which can be in liquid or gas form. By imaging the component using the MRI apparatus, internal and/or external defects of the component can be revealed. In addition, internal and/or external features of interest can examined for dimensional accuracy, among other things.
