Combined with the preparation process and structural characteristics of continuous fiber reinforced titanium matrix composite (TMCs) monolithic blade rings

this paper focuses on the analysis of the difficulties in ultrasonic detection of the internal quality of TMCs monolithic blade rings

and through the ultrasonic detection test and anatomical analysis of specific size of TMCs monolithic blade rings. The main defect types and ultrasonic echo signal characteristics such as fiber breakage

fiber bundle cracking

fiber buckling

fiber extrusion and crack at weld were determined. The test results show that the sensitivity of the inner quality of the integral blade ring of TMCs can reach Φ0.8 mm equivalent flat bottom hole based on appropriate ultrasonic detection process parameters.
