Abstract
A joining surface formed of a composite structure having at least one ply and a peel ply cured to an outer surface of the composite structure, the peel ply including a plurality of microcapsules each filled with a joining material, wherein upon removal of the peel ply from the outer surface of the composite structure, the microcapsules fracture and release the resin to form an uncured surface for joining.
Claims18
A composite joining system comprising:
- a composite structure comprising at least one ply, said composite structure further comprising a work surface;
- a peel ply applied to said work surface, said peel ply comprising:
- a fabric;
- a resin medium infused with said fabric;
- and
- a plurality of microcapsules embedded within said fabric and said resin medium, each of said plurality of microcapsules being filled with a joining material,
- wherein said peel ply and said composite structure are at least partially co-cured, and
- wherein at least a portion of said plurality of microcapsules fracture and release said joining material in response to separation of said peel ply from said composite structure.
5 more elements
A composite joining system comprising:
- a composite structure comprising at least one ply, said at least one ply comprising a plurality of reinforcement fibers embedded with a resin medium, said composite structure further comprising an outer surface;
- a plurality of microcapsules embedded within said resin medium proximate said outer surface, each microcapsule of said plurality of microcapsules is filled with resin,
- wherein at least a portion of said plurality of microcapsules fracture and release said resin to form a resin rich outer surface of said composite structure in response to removal of a portion of said outer surface.
