Abstract
A method and system for a fiber compaction device with interdependent segment travel is described. A compaction device structure supports a series of individual interdependent segments including a compaction surface. Each segment also includes an opening in which a presser member can be located. The presser members consist of either an elastomeric bladder filled with an incompressible fluid or individual pistons that are manifolded together with a fixed volume of incompressible fluid. The presser members create an interdependence in segment positions such that if one or more segments are displaced the others move to balance the segment positions. Having a fixed volume of incompressible fluid allows the segments to work interdependently, thus guaranteeing that the average section position will be the nominal position and eliminating the need for a fixed center section. The segments can conform to complexly shaped part surfaces and apply a uniform pressure against the entire surface to better compact material being drawn through the fiber compaction device.
