PURPOSE:To improve the smoothness along with heat insulation properties by providing high bulk density, by a method wherein carbon fiber felt is wound up and laminated in a vortical state and the carbon fiber felt is unified with a carbide of resin existing with a space between laminated layers. CONSTITUTION:Carbon fiber felt 1 into which, for example, a resin solution is infiltrated for dryness is used for the title material. After the felt 1 of the carbon fiber and a film 2 are fixed to a wind-up body 4 beforehand, the felt 1 of the carbon fiber is fed while applying fixed tension to the film 2 by a tension control part and the felt 1 of the carbon fiber and the film 2 are wound up round the wind-up body 4 while pressurizing them with a press roll 5. A laminated body which has completed winding process is fed to a carbonization process with the normal method after cure and a carbonizable film and/or a net and resin are carbonized. A molded heat insulation material where a laminated part of the felt of the carbon fiber is unified through the carbonized layer, in which the film and/or the net and the resin are carbonized, and the same is superior in uniformity and possesses fixed bulk density and its distribution is obtained, in the carbonization and process. |
