Experiments and finite element modelling have been used to explore a method for miniaturising fibre push-out testing
to the scale of thin ion irradiated layers. Correlation of interfacial surface area to debond stress has been identified for
short fibres, and is related to a size effect following a Weibull distribution. Weibull analysis may be us…
Silicon carbide fibre–reinforced silicon carbide matrix (SiCf/SiC) composites are desirable in structural nuclear applications due to their low density, high temperature strength and tolerance to energetic radiation. We have subjected two industrial grades of SiCf/SiC to high energy He²⁺ ion irradiation, up to 10,000 a…
