High strength, thermally stable magnesium aluminosilicate glass-ceramic matrix-sic fiber composites

摘要: A silicon carbide fiber reinforced barium modified magnesium aluminosilicate matrix composite is described having high strength and thermal stability at temperatures in excess of 1200° C. The material contains about 5% to 14% oxide 25% oxide. While any suitable ratios can be used, the for most applications example, heat engine area, will contain approximately 20% 50% by volume fibers.
