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