A lightweight composite fairing bar () for use in fabricating a composite component () of an aircraft. The fairing bar () includes a core () and an elongated outer shell () surrounding the core (). The outer shell () is comprised of a laminate material, and the core () is comprised of epoxy syntactic foam having a lower density than that of the laminate material. The outer shell () is configured for supporting the composite component () during the manufacture of the same.

Method for manufacturing lightweight composite fairing bar

A method of constructing, assembling and disassembling a mandrel for fabricating a monolithic composite nacelle panel for use on an airplane comprises attaching a first fairing bar including an exposed ball roller assembly to a tilting plate; attaching a first outer section to said first fairing bar; attaching a second outer section to said first fairing bar; attaching a center section to said first outer section and said second outer section; attaching a nozzle section to said first fairing bar and positioned adjacent an inner wall of said first outer section, an inner wall of said center section, and an inner wall of said second outer section; attaching a second fairing bar to said first outer section, said center section, and said second outer section; and attaching a cavity section to said second fairing bar.

Lightweight composite fairing bar and method for manufacturing the same

A method and apparatus for applying variable pressure to selected areas of a bonding assembly jig to shape a face plate to conform to the contours of contoured heads and hold the face plate in place for welding comprises two inverted U-shaped support frames including two spaced apart elongated vertical support members each having a bottom end and a top end, an elongated horizontal top beam extending between and connecting the top ends of the vertical support members, a track extending between and adjustably fastened to the horizontal top beam, and at least one hydraulic press slidably suspended from the track and adapted to apply pressure to a bonding assembly jig. The support frames are provided with wheels and one of the support frames has vertical support members spaced at a distance less that of the other support frame. This arrangement allows the tracks of each frame to be positioned proximate to each other above a bonding assembly jig.
