    Abstract

    X-Radiography with contrast-enhancing organic fluids is a powerful tool for the detection of surface cracks and delaminations in composites. The fluids used for this purpose are tetrabromoethane (TBE) and diiodobatane (DIB). The former is poisonous and mutagenic while the latter damages the composite by decreasing its mechanical13; properties. Hence several alternate fluids have been synthesised and evaluated by us. They were found to have high x-ray opacity and penetrated easily into the microcracks of the sample. They can be used with epoxies, glass, kevlar or carbon fibre reinforced polyesters or phenolics as well as hybrid composites. They do less13; mechanical damage to the composites and are less irritating to the eyes, skin and nose.
