A STUDY OF HIGH MODULUS, HIGH STRENGTH FILAMENT MATERIALS BY DEPOSITION TECHNIQUES.
Abstract
Aluminum oxide filaments were successfully produced. Coatings up to 1.5 mils were obtained on .001 inch tungsten substrates. The resulting filaments had an average tensile strength of 240000 psi. The x-ray spectra of silicon carbide filaments made from SiCl4, trichlorosilane, and trichloromethylsilane were compared. The filaments produced from the two silane compounds showed strong peaks of SiC whereas the spectra for the SiCl4 produced filaments were inconclusive. Work began on the production of beryllium filaments by the zinc reduction of BeCl2. No successful deposit has been obtained to date. (Author)
