[Problem] The present invention addresses the problem of providing: a screw component formed of a two-dimensional carbon/carbon composite material, the screw component achieving a high strength by enhancing the contribution of carbon fibers to the strength of the screw component; and a screw component formed of a two-dimensional carbon/carbon composite material, the screw component being prevented from breakage by relaxing the thermal stress generated therein because of a large change in the ambient temperature where the screw component is used, and being capable of reducing loosening of a screw-fastened part. [Solution] The present invention provides a screw component formed of a two-dimensional carbon/carbon composite material which is produced by stacking anisotropic nonwoven fabrics that use short carbon fibers, the screw component having a configuration wherein the central axis direction of the screw component is oriented so as to coincide with the Y direction (the direction in which less short carbon fibers are oriented) of the two-dimensional carbon/carbon composite material that has anisotropy.

The present invention addresses the problem of providing a muffle structure for a cylindrical furnace (including a vertical cylindrical furnace and a horizontal cylindrical furnace), the muffle structure having high durability and small thermal capacity, and making it possible to reduce operating cost significantly without requiring a large-size manufacturing facility. The cylindrical furnace muffle structure has a polygonal columnar body comprising a plurality of plate members made of carbon/carbon composite material and a plurality of linking members made of carbon/carbon composite material, wherein the plurality of plate members are coupled by means of the plurality of linking members.
[Problem] To provide a spring element that can be used repeatedly even in a high-temperature environment exceeding 1000°C, has high torsional rigidity that enables a large load to be supported, and can be used as a spring washer. [Solution] This spiral annular-shaped spring element is configured so as to comprise a two-dimensional carbon/carbon composite material having a stacked layer configuration in which layers are stacked in the center axis direction of the spring element.
