The tensile strength and elastic modulus of alumino-silicate fibres were calculated by analyzing the results of fibre bundle tensile tests using Weibull statistics. As direct strain measurements on the fibres could not be performed, the recorded experimental data was compliance-corrected to deduce the net fibre strain separately for room and high temperature tests. Fibre strength was lower than the single-fibre test results found in the bibliography, whereas the elastic modulus was in good agreement with reported values, This can be explained by the inherent bundle-testing characteristic which, contrary to the single fibre test used in the reference studies, does not eliminate weaker fibres from the population before testing.
