摘要：A method for fabricating composite structures is provided that includesproviding a skin () that has at least one layer () of uncured composite material, andproviding a flexible hinge tool () that has first and second tooling portions () coupled witha flexible hinge (). The first and second tooling portions () of the hinge tool () each have a

molding surface (), and the tooling portions () are configured to form at least a portion ofa stiffening member (). The method further includes laying up at least one layer () ofuncured composite material on the molding surfaces () to form the stiffening member ().The flexible hinge tool () is positioned on the skin () such that the uncured compositematerial laid up on the first tooling portion () of the hinge tool () contacts the skin (), andsuch that the uncured composite material on the second tooling portion () extends fromthe skin () to form an upstanding segment () of the stiffening member (). The skin () andthe uncured composite material on the flexible hinge tool () are simultaneously cured toform a stiffened composite structure. The flexible hinge tool () is removed by bendingthe tool () at the flexible hinge () such that the first portion () of the tool () peels awayfrom the skin (), and such that the second portion () of the tool () peels away from theupstanding segment () of the stiffening member ().
