Claims3
A method of using a compactor to make a composite stiffener, comprising:
- forming a composite stiffener layup;
- bringing the compactor into contact with the stiffener layup, wherein the compactor is defined by a longitudinal axis;
- adhering the stiffener layup to the compactor;
- using the compactor to transport and place the stiffener layup on a surface;
- flexing the compactor within two generally orthogonal planes intersecting along the longitudinal axis defining the compactor to conform the compactor to the geometry of the surface;
- and
- using the compactor to compact the stiffener layup against the surface.
