“…The interfacial shear properties of continuous fiber reinforced intermetallic matrix composites (IMC) and metal matrix composites (MMC) are the focus of recent investigations which have employed a number of experimental techniques including fiber pull out, fiber push out, and fiber fragmentation tests. Published works on fiber fragmentation tests of MMC include testing of the following composite systems: W/Cu [1,2], SiC/AI 1100 and SiC/AI 6061 [3], SiC/Ti-6AI-4V [4,5], and B/Ti-6Al-4V [5].…”

“…Many investigators have studied the relationship between the thickness and the IFSS, but their results were not consistent. [17][18][19][20] Z-direction fiber bundle specimens of T-3D-C/Cs with different thickness were chosen to be pushed-out for comparison in this work. Based on the Equation.…”

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.

“…In spite of these complexities, the SFF test has been widely applied since it allows simulation of the interfacial load transfer occurring in real composite specimens subjected to longitudinal tensile loading and closely approximates the chemical and thermo mechanical effects present at the interfaces of real composites. It should be noted that the fibre fragmentation characteristics in metal matrix and the resulted interfacial shear strength are largely influenced by the friction arising from thermal residual stresses present in the composite [20].…”

The effect of interfaces on load sharing behaviour has been evaluated by performing single-fibre fragmentation (SFF) experiments and analysis of titanium matrix composites at ambient and elevated temperatures. Fibre breaks were monitored by acoustic emission sensors, and the break locations were determined in-situ by an innovative ultrasonic non-destructive evaluation technique. Data analysis of SFF testing was performed using the Kelly-Tyson model. The length of fibre fragments and distribution were determined using innovative nondestructive technique. This study demonstrates that composite processing conditions can significantly affect the nature of the fibre/matrix interface and the resulting fragmentation behaviour of the fibre. Further, thermal micro-residual stresses, generated during the fabrication process and in-service due to the difference in thermomechanical characteristics of the model composites constituents, play a major role influencing the interfacial shear stress transfer behaviour in single-fibre titanium matrix composites.
