The results indicated that the bat contained multi-walled CNT heterogeneously distributed throughout the epoxy binder of the carbon fibers. Moreover, confocal Raman microscopy was found to be an effective, efficient, and often non-destructive technique for routine determination of CNT distribution in composite materials. CRM also has the ability to distinguish CNT from other carbonaceous materials such as C60, polymers, or epoxies present in consumer products.
