Abstract
This paper presents results on monitoring initiation, accumulation, and progression of matrix splitting through acoustic emission in double-edge notched graphite/epoxy coupons. In this specimen geometry matrix splitting is the single dominant mode of damage. Detailed acoustic emission data analysis was performed by which most of the emission generated by the grating among the split fracture surfaces has been identified. Only the acoustic emission generated by the actual growth of matrix splitting has been accounted for. Based on the location distribution histograms of these events the progression of the matrix splits could be tracked. The acoustic emission results were compared with optical observations and excellent correlations were established for all cases studied.
