Abstract
A one-piece or otherwise unitary annular shim member made from a perforated metallic material is used to maintain a space between stacked annular preforms during a manufacturing process, such as densification. The metallic material used preferably can withstand at least the temperatures encountered during densification. The one-piece structure advantageously simplifies the arrangement of the preforms in a process chamber and causes less deformation in the preforms. In one example, the shim member is made from a metallic mesh and may utilize a crimped weave structure.

An annular shim member having first and second opposing surfaces and a plurality of openings formed therethrough,
- wherein the member is made from a metallic material, has an effective thickness of about 1 mm to about 6 mm, and at least partly defines a plurality of radially extending gas flow paths for communicating a radially interior side of the member with a radially exterior side of the member, the annular shim member being substantially planar.
