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.

A tubular web for use in furnace atmosphere of a temperature higher than 1,200°C., which consists of at least two layers of carbon fiber filaments having a tensile strength of 100-500 kg./mm.2, one of said two layers being composed of said carbon fiber filaments wound up cylindrically with a diameter corresponding to the diameter of said tubular web, and the other of said two layers being composed of said carbon fiber filaments wound up over said one layer cylindrically so as to make innumerable intersections with the carbon fiber filaments of said one layer, and the filaments of said layers being bound integrally to each other by adhesives primarily at said intersections to form a tubular web having a thickness of less than 1 mm.
