Zylindrischer Gegenstand aus faserverstärktem Verbundwerkstoff und Verfahren zu dessen Herstellung

摘要

The disclosed method can manufacture a thick-walled cylindrical part of an excellent quality which is free from the interlayer separation, by using a fiber reinforced plastic composite material. The fiber reinforced plastic composite material having a small thermal expansion coefficient is laminated in the circumferential direction of a mandrel; the laminated fiber reinforced plastic composite material layer is heat-cured to form an auxiliary member of the mandrel; a plurality of sorts of fiber reinforced plastic composite materials having a different elastic modulus, respectively are laminated on the formed auxiliary member; and the laminated fiber reinforced plastic composite materials are all heat-cured.
