For providing a fabric that has a low frictional property and can exhibit long-term tribological properties even when the fabric is subjected to a high-speed frictional force under a high load, there is provided a fabric according to the present invention is a fabric in which a composite yarn of fluororesin fibers A and fibers B other than fluororesin fibers is used for at least one of a warp yarn and a weft yarn, and the fabric is characterized in that a mass ratio α of the fluororesin fibers A in the composite yarn is 5 to 70%, and a ratio of the area ratio X of the fluororesin fibers in a fabric surface to a mass ratio Y of the fluororesin fibers in the fabric is 1 or more and 5 or less. This fabric can be usefully used for a cable cover for a robot arm.

For example, provided is an RFID-bearing flexible material, in which an RFID is attached to a flexible material, the RFID includes an antenna portion, and the antenna portion is formed of a conductive linear body containing a carbon nanotube yarn.

An rear fairing for a pylon supporting an aircraft turbojet engine forms an aerodynamic surface covering the base of the pylon. The rear fairing is elongated in a longitudinal direction and includes a floor arranged opposite the hot gases exiting the turbojet engine and side walls constituting aerodynamic surfaces. The floor and the side walls include ceramic matrix composite materials made from preforms formed by layers of superimposed warp and weft yarns, the preforms have interlayer weaving yarns connecting the layers to one another.

A polar plate is fabricated. The polar plate is flexible and made of a plastic graphite composite. No matter a supporting member is used for calendering or not, a thin polar plate with controllable thickness is fabricated. The polar plate is excellent in blocking the through-transmission of vanadium ions and the limit of blending ratio of conductive carbon is broken through. The longitudinal through-transmission volume resistivity (proportional resistance to thickness) is greatly improved by adjusting the blending ratio of conductive carbon for meeting the demand of conductivity. In the mean time, the present invention strengthens the rigidity required for the thin polar plate while providing large-area polar plate fabrication for industrial use and convenience and provides a cooling and pressing method for patterning a composite polar plate. An integrated mold is thus obtained to replace the conventional polar plate which needs to be processed and prepared with runner.
