ATTACHMENT OF COMPOSITE ARTICLE

摘要

A composite article including composite component mounted on a spar including a shank extending heightwise from below component base up into composite component. Tab at an upper end of shank substantially or fully embedded in the composite component and at least one ply surface pattern of the composite component contacting and generally conforming to at least one spar surface pattern on the tab.;Spar surface pattern may include spaced apart spar surface protrusions with spar surface spaces therebetween and spar surface protrusions extending outwardly from spar and disposed between tows in ply surface pattern. Tows may be layed up in spar surface spaces. Spar surface pattern may include continuous or segmented spaced spar surface protrusions and spar surface spaces therebetween with tows in ply surface pattern disposed in spar surface spaces. The composite article may be a composite blade or vane including a composite airfoil.

1. A composite article comprising:
a composite component extending heightwise from a component base to a component tip and lengthwise between spaced apart component first and second edges, the composite component including plies having widthwise spaced apart ply first and second sides and ply edges therebetween, the composite component mounted on a spar including a shank extending heightwise from below the component base up through the component base into the composite component, a tab at an upper end of shank and substantially or fully embedded in the composite component, the tab including heightwise spaced apart tab base and tab tip, and at least one ply surface pattern of the composite component contacting and generally conforming to at least one spar surface pattern on the tab.
