CERAMIC MATRIX COMPOSITES EXHIBITING HIGH INTERLAMINAR SHEAR STRENGTH

摘要

Fiber-reinforced ceramic matrix composites incorporating a glass-ceramic matrix of lithium aluminosilicate composition in which is disposed a fiber reinforcement phase including at least one layer of unidirectionally oriented fibers (e.g. SiC), the matrix further comprising a whisker reinforcement phase selected from the group of SiC, alumina, HfC and Si3N4, the whiskers imparting substantially improved transverse modulus of rupture strength and interlaminar shear strength to the composite.
