Effects of interfacial bonding on sliding phenomena during compressive loading of an embedded fibre

The effects of interfacial bonding on the sliding phenomena at the fibre/matrix interface are considered for fibre-reinforced ceramic composites when an axial compressive stress is applied at the exposed end of an embedded fibre. Sliding occurs at the interface when the interfacial shear strength is exceeded. The interfacial shear stress, the stress transfer from the fibre to the matrix, the length of the sliding zone, and the fibre displacement are analysed in the present study. The results show that at a fixed load, the sliding length and the fibre displacement decrease with increase in the interfacial shear strength. Effects of interfacial bonding on the applied stress-fibre displacement relationship during compressive loading and subsequent unloading are also revealed.
