Abstract

Silicon carbide fibres have proven to be an excellent reinforcement material in ceramics and other composites due to their high strength and stiffness and good thermomechanical stability. The thermal diffusivity/conductivity of SiC based fibres has been reported earlier [1]. The methods used so far for the fibres have been mainly indirect and based on using a composite of known composition and then applying a standard thermal conductivity measurement on that system. Fiber properties have further been obtained from an inversion calculation. Direct measurement data of fibre properties has not been available.
