Silicon oxycarbide glass fibers have been successfully drawn from organically modified silicates (ORMOSILs) by the sol-gel method. The gel fibers were drawn from a precursor composed of tetraethyl orthosilicate (TEOS) and polydimethyl siloxane (PDMS) with different weight fraction. The organics in the fiber underwent decomposition to at temperatures higher than 300 degrees C. The existence of oxycarbide phases were detected using infrared spectroscopy and solid state Si-29 NMR and was found in the fibers with heating temperatures higher than 700 degrees C in nitrogen atmosphere. X-ray powder diffraction patterns showed that the fibers were still amorphous even after heat treatment at 1000 degrees C for one hour.
