Abstract
This invention is directed to a surface treatment for SiC monofilament developed for the purpose of increasing the transverse strain-to-failure of composites, particularly aluminum composites. The surface treatment includes a fine grain SiC region adjacent to the bulk or stoichiometric SiC region and a transition region which interacts with the matrix material.
