CARBON FIBER PREFORM, CARBON FIBER REINFORCED PLASTIC, AND METHOD FOR PRODUCING CARBON FIBER PREFORM

摘要

An object is to manufacture a preform having an insulating material by equipment of simplified configuration. Solution A carbon fiber preform has a plurality of carbon fiber sheets that are stacked and are bonded to each other by means of an adhesive resin having thermal plasticity. This carbon fiber preform comprises a partial-conducting layer arranged at least either between at least one pair of adjacent layers of the plurality of carbon fiber sheets or on a surface area of the plurality of carbon fiber sheets and configured to have a resistance area which has higher electric resistance than electric resistance of the carbon fiber sheet in a stacking direction and a conductive area which is capable of having electrical continuity in the stacking direction, wherein the resistance area and the conductive area are arranged in a surface direction orthogonal to the stacking direction. The plurality of carbon fibers sheets are bonded to each other by means of the adhesive resin in the surface direction in the conductive area and in an area corresponding to periphery of the conductive area. In areas other than the conductive area and the area corresponding to the periphery of the conductive area, the plurality of carbon fiber sheets are not bonded to each other by means of the adhesive resin.
