They have all been produced by foil-fiber-foil compactions see Section . The SiC fiber used in all cases is the SCS-6 monofilament. This fiber has a nominal UTS of 500 ksi with a 50-60 Msi modulus. Due to these high values the fiber properties dominate in directions parallel to the fiber axis in the composited form. The SCS-6 monofilament is coated with a double-pass carbon-rich layer. This coating protects the surface of the fiber from handling damage. Additionally it acts as a diffusion barrier to prevent reaction of the titanium matrices with the SiC fiber during consolidation. The coating forms a weak interface which leads to fiber matrix debonding and low transverse properties. Thus the properties of the materials listed in this section are extremely anisotropic. SILICON CARBIDE TITANIUM SiC Ti-15-3 Composite plates were consolidated by Textron using the foil-fiber-foil method. The matrix foils were of the alloy Ti-15V-3Cr-3Al-3Sn Ti-15-3 and the reinforcement was the SCS-6 fibers. Plates were either 8 or 32-ply thick and had dimensions of 10 x 14 . All fiber mats used in these plates were woven with metallic ribbons. The type of ribbon used Ti Mo or Ti-Nb .
