A method of making a composite bond cascade made up of a plurality of parallel vanes and intersecting beams, the steps including: using a plurality of angular metal frames stacked one on top of the other; inserting the frames around a metal tool mold, the mold having an opened top and bottom and openings in the sides and ends of the mold; securing continuous first fibers on one side of the frame and extending the first fibers through the openings in the sides of the mold across to the opposite sides of the frame and securing the first fibers thereto, the first fibers disposed one on top of the other forming a wall of the vane; securing continuous fibers on one side of the frames with the second fibers disposed in a spaced relationship from the first fibers and extending the second fibers through the opening in the sides of the mold across to the opposite sides of the frame and securing the second fibers thereto, the second fibers forming a wall of an adjacent vane; securing continuous third fibers on one end of the frames and extending the third fibers through the openings in the ends of the mold across to the opposite ends of the frame and securing the fibers thereto, the third fibers forming a wall of a beam; securing continuous fourth fibers on one end of the frames and extending the fourth fibers through the openings in the ends of the mold across to the opposite ends of the frame and securing the fibers thereto, the fourth fibers forming a wall of an adjacent beam; inserting a fabric around and along the sides of the parallel vanes and intersecting beams; inserting a plug to fill the cavity between the first and second fibers and the third and fourth fibers; and heating and curing the fibers and removing the plug therefrom.
