|a A variety of nondestructive evaluation techniques were utilized to document the damage characteristics of a Si₃N₄-BN fibrous monolith. The techniques included X-ray radiography, infrared thermography, ultrasonic C-scanning, and acoustic emission detection. The focus of this paper is the nondestructive evaluation results from a modified single-edge notched tensile specimen inspected before and after testing. Of the techniques performed, the thermography and ultrasonic methods were the most successful at identifying the predominant types of damage incurred in the fibrous monolith material. Polished cross-sections of the specimen revealed that hairline cracks had developed along inter- and intra-laminar BN cell bundle boundaries. Neither type of crack could be identified from the X-ray radiograph. The delaminated zones were matched with results from the thermography and C-scans. The acoustic emissions correlated well with changes in the load-displacement data and provided source locations consistent with the thermal and C-scan images.
