    摘要: 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.

    摘要: Apparatus and methods of stretch-forming pre-preg material are provided. In one example embodiment, a variable material stretch-forming apparatus comprises a stretch-forming assembly configured to stretch-form at least one section of a sheet of pre-preg material to a longer length than at least one other section of the sheet of pre-preg material before the sheet of pre-preg material is applied to a tool.
