Abstract
A composite structure and methods are presented. A method of performing a composite repair is presented. A fiber mixture is forced through a composite structure and into a void of the composite structure, the fiber mixture comprising an adhesive and a plurality of electromagnetically steerable fibers. An electromagnetic field is applied to the fiber mixture within the void of the composite structure. The adhesive of the fiber mixture is cured to form the composite repair with structural capabilities.
Claims23
A method of performing a composite repair comprising:
- forcing a fiber mixture through a composite structure and into a void of the composite structure, the fiber mixture comprising an adhesive and a plurality of electromagnetically steerable fibers;
- applying an electromagnetic field to the fiber mixture within the void of the composite structure;
- and
- curing the adhesive of the fiber mixture to form the composite repair with structural capabilities.
(canceled)
A method of performing a composite repair comprising:
- forcing a fiber mixture through at least one injection hole in a composite structure and into a void in the composite structure, the fiber mixture comprising an adhesive and a plurality of electromagnetically steerable fibers;
- applying an electromagnetic field to the fiber mixture within the void after introducing the fiber mixture into the void;
- and
- curing the adhesive of the fiber mixture to form the composite repair with structural capabilities.

(canceled)
A composite structure with a composite repair having structural capabilities, the composite structure comprising:
- a plurality of cured composite plies with a void creating a separation within the plurality of cured composite plies;
- a number of injection holes connecting the void to an exterior of the plurality of cured composite plies;
- and
- a cured resin with a plurality of electromagnetically steerable fibers within the separation forming the composite repair and configured to transmit forces to composite plies in contact with the composite repair.
