Method for producing composite structure and composite structure produced thereby

A method for producing a composite structure having a three-dimensionally curved portion (2) and a cylindrical portion (3), comprising the steps of: (a) placing an outer skin (4) made of a composite prepreg on a forming die; (b) mounting a honeycomb core (6) on a portion of the outer skin that forms...

Zusammenfassung:	A method for producing a composite structure having a three-dimensionally curved portion (2) and a cylindrical portion (3), comprising the steps of: (a) placing an outer skin (4) made of a composite prepreg on a forming die; (b) mounting a honeycomb core (6) on a portion of the outer skin that forms the three-dimensionally curved portion; (c) superimposing an inner skin (5) made of a composite prepreg thereon; (d) arranging a preformed frame member (8a) and a preformed stringer member each made of a composite prepreg on a portion of the inner skin that forms the cylindrical portion to prepare an assembly; and (e) forming the assembly by heating under a pressure. A composite structure of the present invention can be produced by the method.
