Carbon fibres were pretreated by means of an interfacial in-situ polyamidation technique resulting in a polyamide coating of the fibres. The procedure followed involved successive application to the carbon fibres of two immiscible solutions of hexamethylenediamine and adipoyl chloride. Previous work conducted in our laboratory on chrysotile/epoxy composites coated with Nylon 6,6 provided interesting results when the tensile performance was evaluated. This behaviour was attributed to the improved affinity between matrix and asbestos fibres as a result of the well-known compatibility between polyamide and the epoxy phase. In this study emphasis is given to the coating of long carbon fibres such as are used for the preparation of unidirectional carbon/epoxy composites. The mechanical properties of uniaxial laminates with varying fibre volume fractions and polyamide contents are then compared with those of uncoated carbon fibres. © 1993. (EN)
