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 induction welding a composite part, the method comprising:
- acquiring a first composite part that includes fibers impregnated with a thermoplastic;
- acquiring a second composite part that includes braided electrically conductive fibers and braided electrically insulating fibers impregnated with the thermoplastic;
- placing the first composite part in contact with the second composite part at a location occupied by the electrically conductive fibers;
- and
- induction welding the first composite part to the second composite part at the location.
