“…However, to date, the IFSS of C/Cs has been successfully determined only by fiber push-out tests. [13,16] In this work, the fiber bundle push-out test was performed using an electric-driven testing machine at a displacement rate of 0.5 mm/min. The procedure of this test is illustrated 166…”

Carbon/carbon composites (C/Cs) are widely used as thermal protection materials in aviation and aerospace field. Most of the fracture processes of C/Cs have been found to be profoundly affected by their interfacial properties. Specially arranged fiber bundle push-out test was utilized to determine the fiber bundle/matrix interface shear strength of one threedimensionally reinforced C/Cs. In order to reveal the link between the interfacial properties and the failure behavior, the micromechanisms of damage initiation at the notch tip on the C/Cs was investigated in real-time during the flexural fracture tests through scanning election microscopy. Real-time fracture observation revealed that the damage was nucleated in the fiber bundle/matrix interfaces around the notch tip and the failure crack was successfully observed along the fiber bundle/matrix interface. Fiber yarns acted as an obstacle to crack propagation hence it was necessary to increase the load to propagate the crack through the next fiber yarn.

“…The test method used for the interfacial measurements is illustrated in Fig. 2 [16,17]. In this test, a rectangular specimen in which slits had been engraved, leaving only the fiber bundle along the centerline of a specimen, was subjected to compressive load, in response to which the fiber bundle protruded.…”
