The goal of this study was to prepare SiC-reinforced silicon matrix composites. Chemical vapor deposition techniques were employed to deposit Si onto the surface of SiC fibers and to infiltrate silicon carbide fibers to form a cylindrical composite. A mixture of SiCl{sub 4} and H{sub 2} was reacted at 1,000{degree}C to produce the Si coating. The morphology of Si deposition was monitored by scanning electron microscopy. The structural properties of the composite were studied by powder x-ray diffraction methods. Surface studies of the composites were investigated with x-ray photoelectron spectroscopy.
