Abstract: An experimental methodology to photograph bubbles in-situ during infusion of carbon reinforcements has been developed and demonstrated previously. This method is based on fluorescent photography of bubbles at the surface of the reinforcement during infusion. Previous work with this experimental methodology was done with test oils, but has now been characterized with a curing epoxy resin. The results of in-situ bubble photography at the surface are now compared to standard defect characterization methods including ultrasound and image analysis of polished cross-section micrographs. Such experimental results are meant to provide the data required to build process optimization models capable of prediction of the final void distribution and morphology of voids.
