  • Z-PIN PATCH AND METHOD FOR MANUFACTURING OR COUPLING A COMPOSITE LAMINATED STRUCTURE USING SAME
    Publication number: 20140250665
    Abstract: Provided are a Z-pinning patch capable of improving process efficiency, productivity, and the like, by allowing Z-pinning of a composite laminated structure to be realized using a structure as simple as possible, and a method for manufacturing or jointing composite laminated structures using the same. The Z-pinning patch used for Z-pinning for reinforcing delamination performance of composite laminated structures or connecting between a plurality of laminated members, includes: a base plate formed in a plate form; and a plurality of pins fixed to one side of the base plate.
