Manufacturing methods and the FRP cryostat of the FRP cryostat

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing an FRP cryostat by bonding a plurality of members which ensures the strength of bonded portions of the respective members, is strong against mechanical shock and thermal shock, and is less prone to the occurrence of vacuum leak, and an FRP cryostat manufactured according to the manufacturing method.;SOLUTION: The method for manufacturing an FRP cryostat comprises a member manufacturing process of manufacturing each of a plurality of FRP members 11a, 11b, a taper forming process of forming tapered surfaces 12a, 12b on outer surfaces near bonded portions of the respective FRP members, an overlapping piece forming process of forming overlapping pieces 13a, 13b for overlapping both end surfaces of the FRP members inside and outside, respectively, a member bonding process of overlapping the overlapping pieces of the respective FRP members to be bonded, a prepreg laminating process of attaching prepregs on both tapered surfaces of bonded FRP members to be laminated, and a prepreg curing process of deaerating the laminated prepregs to thereby cure the prepreg.;COPYRIGHT: (C)2007,JPO&INPIT
