    Abstract: In a bending portion of a conduit, a gap between a lining material and an inner surface of the conduit is minimized. A lining material 1 obtained by rolling a lining material sheet into a tubular form is installed in a conduit P with both ends of the lining material sheet 1 in its circumferential direction circumferentially overlapping each other. In this process, the lining material 1 is installed so that, in a bending portion P3 of the conduit P, an overlapping portion 1a where the both ends of the lining material sheet 1 overlapping each other faces toward an outer curvature side of the bending portion P3. Then, the diameter of the lining material 1 installed in the conduit P is expanded with the both ends of the lining material sheet 1 circumferentially slid on each other. This facilitates inflation of a portion of the lining material 1 which portion faces toward the outer curvature side in the bending portion P3, thereby to decrease the gap between the lining material 1 and an inner surface of the bending portion P3.

    Abstract: 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.
