Evaluation of interfacial stress in fibre reinforced composites using the slice compression test
The slice compression test is a novel technique for measuring the interfacial shear stress in fibre reinforced composites. The composite slice is compressed between a ceramic anvil, where there is a constant strain condition, and a ductile metal replica, where there is a constant stress condition. The modulus mismatch between fibre and matrix results in debonding of the interface and then interfacial sliding. Measurement of fibre protrusion heights enables calculation of the interfacial shear stress. The technique is investigated for a range of composite systems including SiC monofilament reinforced metal and ceramic matrices, carbon fibre reinforced ceramics and SiC reinforced glass-ceramics. Particular attention is paid to testing conditions to avoid the onset of matrix cracking, which results in erroneous measurements of fibre protrusion length.
