    Abstract: Hardenable or polymerizable epoxy resin-based composition, characterized in that its hardener system comprises a combination in synergic quantities of:(i) at least one imidazole which, alone, can cause the polymerization of the epoxy resin only at a temperature above about 75.degree. C.,(ii) at least one polyamine compound which, alone, leads to the polymerization of the epoxy resin at a temperature lower than about 75.degree. C. Such a resin is particularly suitable for the manufacture of composite structures, applicable in particular in ship- or boatbuilding.

    Abstract: A process for the manufacture of a prepreg comprising feeding a layer of unidirectional conductive fibres having a defined width, bringing into contact with a first face of the fibres a first layer of resin comprising thermosetting resin, and compressing the resin and fibres together by passing over one or more impregnation rollers, wherein the pressure exerted onto the conductive fibres and resin does not exceed 40 kg per centimetre of the width of the conductive fibres, and the resin being in sufficient amount for the resin to enter the interstices of the fibres and leave a first outer layer of resin essentially free of unidirectional conductive fibres.
