摘要： 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.

摘要： Mechanically attaching articles made from composites has problems due to the difference in properties of the composite in the x, y planar direction and the z perpendicular direction, this results in different properties between the composite and the attachment member such as differences in coefficients of thermal expansion which can weaken the joint further leading to differences in moisture uptake which can further reduce the strength and robustness of the joint. The invention relates to the selection of the position of a joint in order to reduce such problems and to operating the moulding process in a way that improves the provision of mechanical attachments such as bolt holes.
