Summary

The Vickers microhardness technique was used to characterize a new composite material, Siconex,™ made from Nextel 312 fibers coated by chemical vapor deposition (CVD) with Sic. The objectives were to determine the hardness of the two components as well as to acquire information about interfacial stresses between fiber and matrix. As-manufactured materials were tested and compared with materials having been heat-treated at 1250°C for 10 hours. Some of the experimental difficulties will be discussed.
