An experimental study is carried out to characterize the failure behavior of a fiber reinforced polymer matrix composite at the micro-scale using in-situ testing. Micron-sized specimens of IM7/BMI composite were fabricated using Focused Ion Beam milling. The specimens were compression tested using a custom built, SEM/X-ray CT-based in-situ micro-testing fixture. During compression, SEM images are acquired continuously between displacement intervals so the deformation phenomena can be observed. The in-situ fixture was also used to reload the sample in an X-Ray CT machine. Intermediate resolution x-ray CT data was acquired both in loaded and unloaded states to fully resolve the deformation in 3D. Furthermore; high-resolution CT scans taken of the standalone sample allowed an exact mapping of the fiber locations that was then overlaid with the lower resolution CT data to allow for higher accuracy volumetric feature tracking during in-situ testing.
