METHOD OF ANALYZING STRUCTURE OF RESIN MATERIAL

Method for x-ray inspection of a structure made with thermoplastic resin wherein the resin material is impregnated with a contrast medium. The contrast medium comprises a solvent and a radiopaque compound that contains an element with an atomic number equal to or greater than 9, i.e. fluorine or hea...

Zusammenfassung:	Method for x-ray inspection of a structure made with thermoplastic resin wherein the resin material is impregnated with a contrast medium. The contrast medium comprises a solvent and a radiopaque compound that contains an element with an atomic number equal to or greater than 9, i.e. fluorine or heavier. The solvent is selected such that the relative energy difference (RED1) represented by Ra1/R01 is 1.8 or less, where R01 is the interaction radius of the thermoplastic resin in a Hansen space and Ra1 is a distance between the Hansen solubility parameters of the thermoplastic resin and the solvent.
