Abstract:
1. A method of creating a joint between a metallic component and a composite component, the method comprising: identifying a first area wherein stresses normal to the composite component are above a predetermined threshold that would initiate delamination of the composite component; identifying a second area wherein stresses normal to the composite component are lower than the stresses in the first area; forming attachment projections on the metallic component to form a distribution, the distribution comprising a first number of attachment projections in the first area wherein the first number of attachment projections maintains structural integrity of the composite component within the first area and a second number of attachment projections in the second area wherein the second number of attachment projections in the second area maintains structural integrity of the composite component within the second area, wherein the first area has a higher concentration of attachment projections than the second area; and engaging the composite component and the metallic component by extending the attachment projections from the metallic component into the composite component, the attachment projections penetrating into and not through the composite component, to form the joint.
