RADIOPAQUE FOAM

Abstract:

Embodiments are directed to a radiopaque foam used to repair composite structures. A method for creating the radiopaque foam comprises providing first and second resin components that are radiolucent to x-ray imaging. A barium sulfate component is combined with the second resin component. After combining the barium sulfate component and the second resin component, the first resin component and the second resin component are mixed to create a pourable foam. An amount of barium sulfate combined with the second resin component is sufficient to render the pourable foam radiopaque to x-ray imaging.
