Abstract
A shaped article comprises a ceramic matrix and dispersed therein in the range of 5 to 30 weight percent mechanically added silicon carbide, said article having a modulus of elasticity (E) value of at least 10 percent greater than the inherent elastic modulus value of the fully dense host matrix. The articles are useful as high temperature stable reinforcement materials in composites requiring a high modulus of elasticity.
