Abstract

A device for compacting a contoured elongate composite layup includes flexible first and second fiber reinforced resin flexible sections flexible along their lengths. The first section is flexible within a first plane and the second section is flexible within the first plane as well as within a second plane.

Claims (11)

1. 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.

2. The method of claim 1 , wherein adhering the stiffener layup to the compactor includes:

generating a vacuum inside the compactor, and

using the vacuum to suck the stiffener layup against the compactor.

3. The method of claim 1 , wherein sucking the stiffener layup against the compactor includes generating a suction force by draw air through sides on the compactor in contact with the stiffener layup.
