Carbon or inorganic fibers are wound up cylindrically so as to have numerous intersections to each other. They are bound integrally to each other at points including their intersections to form cylindrical component parts which may be used within an extremely high-temperature furnace, such as when used as parts of belt conveyors and trays for carrying articles to be treated within the furnace. The cylinders thus made are comparatively thin and extremely light in weight, while they are afforded with a tensile strength sufficiently high enough to stand against loads exerted thereupon in the furnace.
