摘要：

This study is concerned with the influence of the strength of the fibre/matrix interface on the strength and failure process in uniaxial arrays of carbon fibres in an epoxy resin. A batch of high-strength carbon fibres has been supplied with several levels of an oxidative surface treatment to produce composites with various interface strengths. Tensile tests have been conducted on single fibres, on loose bundles and on tows impregnated with an epoxy resin. Further tests have been conducted to estimate the interface strength. A hybrid-tow test configuration has then been used to follow the sequence of failure within a single tow of the carbon fibre in a uniaxial composite. The results indicate that the fibre strength is affected only slightly by the surface treatment, the strength of impregnated tows is reduced, and their mode of failure and that of the hybrid tows is affected significantly.
