Notch sensitivity of two C-SiC fibre-reinforced ceramics

摘要

The notch sensitivity of two carbon fibre reinforced silicon carbide composites has been studied. Tensile strength test of a notched an unnotched specimens have been performed. Fractography has been used for the identification of damage evolution during the tensile load of the double notched specimens. The materials were found notch insensitive in the form of specimens with width from 8 mm to 14.5 mm, loaded in tension at room temperature.
