Strength of Glass Fibres

Abstract

AN attempt has been made to eliminate the effect of surface discontinuities on the tensile strength of glass fibres by producing specimens coated with a glass which at elevated temperatures behaves as a viscous liquid whilst the core remains a brittle solid. Assuming some inter-diffusion at the boundary between the two glass compositions it was expected that the silicon oxygen random network structure of the two glasses would be continuous across the boundary and that there would be a gradual transition, on the molecular scale, from the solid to the liquid phase.
