A bonded joint for use in bonding composite materials is provided and includes a composite rib having electrically conductive properties and a composite structure having electrically conductive properties. An electrically conductive preform is provided that facilitates a bond between the composite rib and the composite structure. A mesh composition that bonds the composite rib to the preform and that bonds the preform to the composite structure is provided and is electrically conductive to conduct current between the composite rib and the composite structure.

An edge concealment system for abating electrical discontinuities between externally exposed edges of adjacent surface pieces separated by a gap. The system includes a cover component shrouding each edge and able to absorb or conduct incident radar energy. A male element and a female element extend between the cover component and the surface piece for positive engagement of the male element within the female element and retention of the cover component with the surface piece. Preferably the engagement of the male and female elements includes an audible signal such as a click sound when the engagement occurs so that operators are confirmatively advised upon positive placement.
