Abstract
A thermostructural composite article and a method for making in which the article comprises silicon carbide reinforcing fibers having an oxygen content by weight of not more than about 14% and an average diameter of less than about 20 microns in a refractory matrix at least partially formed by chemical vapor infiltration. The fibers in the composite article of the invention have an end-to-end fiber diameter uniformity ratio of less than about 1.5.
