The Carborundum Company and the High Temperature Materials Laboratory (HTML) at Oak Ridge National Laboratory have been performing detailed characterization of VLS SiC fibrils as part of the effort to scaleup the VLS process. The characterization of fibrils requires evaluation of a wide variety of properties, including physical parameters (diameter, length, and morphology), chemical properties (bulk chemistry and trace impurity concentrations) and mechanical properties (tensile strength, modulus and creep resistance). Taken together, these properties will help determine the performance of the fibrils as a reinforcement phase in advanced composite applications.
The purpose of this paper was twofold. The main purpose was to describe several techniques or analytical procedures which have been used to evaluate the effects of synthesis and post-processing conditions on fibril characteristics. The secondary goal was to review literature date which highlight the attractive characteristics of VLS SiC fibrils as a reinforcement for ceramic matrix composites.
