Abstract
Systems and methods are provided for fabricating a hybrid composite part. A method includes braiding a first set of fibers to form a weave having a closed cross-sectional shape, braiding a second set of fibers into the weave that are chemically distinct from the first set of fibers, impregnating the weave with a resin, and hardening the resin within the weave to form a hybrid composite part.
Claims20
A method for fabricating a hybrid composite part, the method comprising:
- braiding a first set of fibers to form a weave having a closed cross-sectional shape by axially displacing an end effector of a braiding robot;
- adding a second set of fibers into the braiding that are chemically distinct from the first set of fibers by axially displacing the end effector of the braiding robot, causing fibers in the second set of fibers to be interwoven with the fibers in the first set of fibers;
- impregnating the weave with a resin;
- and
- hardening the resin within the weave to form a hybrid composite part.
