PROBLEM TO BE SOLVED: To provide a crucible made of carbon fiber reinforced carbon composite which is restrained in separation of carbon fiber and deformation while using by reducing machining of a bottom part of the crucible as much as possible after forming the crucible by the filament winding method. SOLUTION: The crucible is integrally formed by winding into multi-layers by filament winding method, the carbon fiber is wound such that an inner most 1st layer 2 is made with an orbit passing though a pole O in the bottom 12, a 2nd layer 3 is wound with an orbit passing a 1st hill side of bulging part 6 which is made by the carbon fiber of the 1st layer concentrated to the pole O and forming a bottom of a 1st outer ring 8, each layer successive to 3rd layer 4 is wound with each orbit forming bottom of outer ring passing the hill side of outer surface of inner layer spreading stepwise toward outer side. The heights of tops of bulging parts formed by carbon fiber for multi-layers are almost same. |
