Abstract

An investigation is reported of the effect of boron modification on the mechanical properties of carbon fibres. It was found that the presence of boron in the furnace atmosphere does not affect the important structural features of the bulk of the fibres, that in many fibres the added boron is largely confined to the near-surface regions of the fibres, and that a large fraction of the boron is present as boron carbide. The largest improvements in strength were obtained when both carbon and boron were present in the furnace atmosphere.
