Abstract
A composite structure and methods of forming composite structures are provided. A composite structure comprises a first composite part; a second composite part welded to the first composite part at a joint; and the joint between the first composite part and the second composite part comprising doped fibers.
Claims21
A composite structure comprising:
- a first composite part;
- a second composite part welded to the first composite part at a joint;
- and
- the joint between the first composite part and the second composite part comprising doped fibers.
1 more element
A method of welding two composite parts to form a composite structure, the method comprising:
- forming a first composite part with a doped prepreg ply comprising doped fibers at a first surface of the first composite part;
- positioning a second composite part in contact with the first surface such that the doped prepreg ply is positioned at a joint between the first composite part and the second composite part;
- and
- welding the first composite part and the second composite part at the joint using heat generated by the doped fibers in response to an electromagnetic field.
1 more element
A method comprising:
- doping fibers to form doped fibers with increased conductivity;
- forming a doped prepreg ply comprising the doped fibers;
- applying the doped prepreg ply to a first composite part;
- and
- positioning a second composite part relative to the first composite part such that the doped prepreg ply is positioned between the second composite part and the first composite part.
