The Strength of Tungsten-Cored Silicon-Carbide Fibres and the Influence of a Polymer Matrix
Silicon carbide fibres of 100 µm diameter were tested in tension at various gauge lengths in air, embedded in two polymer matrices and with thin coatings of a polymer. It has been shown that the tensile strength distribution is strongly influenced by these variables. It appears that coating or embedding inhibits failure from surface flaws at strains which would otherwise have led to failure.
