摘要：
The present invention provides: (1) a formed tubular thermal insulator comprising a felt piece of carbon fibers spirally wound to form a laminate of felt layers integrally bonded to each other with the carbonized substance present between the felt layers with substantially no wavy deformation of spiral winding form, and (2) a process for preparing a formed thermal insulator, the process comprising spirally winding a felt piece of carbon fibers and a film and/or net with a carbonizable resin inserted therebetween while applying a tensile force on the film and/or net to form a laminate, followed by curing and carbonization.
