A method of composite joining and repairing includes providing complementary matching and interlocking bondline surface configurations in composite materials and the material to which the composite materials are to be bonded, interlocking the two materials at their bondline, and thereafter adhering at least one patch onto both of the surfaces of the interlocked combination of materials, thereby securing the composite to the other material. Anisotropic materials can be adhered to isotropic materials by this method. The advantages of the method include increased bond strength resulting from the joining. Consequently, fiberglass vehicle parts can be repaired, to achieve the original strength of the part, or in the alternative, parts can be originally machined in the bondline configurations so as to enable easy manufacture of new vehicle components.

A method for repairing a portion of a fiber-reinforced resin composite material structural member subjected to forces in a plurality of directions, said method comprising the steps of: identifying a damaged portion of the structural member; defining a cutting path on the structural member around said damaged portion, wherein said cutting path is non-linear and includes at least one projection or recess; cutting along said cutting path to remove said damage portion from the structural member and to provide the structural member with a defined periphery; creating a repair piece of a fiber-reinforced resin composite material; forming a piece periphery of the repair piece complementary to the defined periphery; aligning the piece periphery with the defined periphery; joining the repair piece with the structural member by mechanically interlocking the defined periphery of the structural member and the piece periphery of the repair piece to form a projection and recess type connection; and adhering at least one fiber-reinforced patch onto an outer surface adjacent the defined and piece peripheries to cover and strengthen the peripheries and form a three dimensional bond.
