摘要
Constraint fixture for processing annular preforms. The constraint fixture is made up of a lower plate (2), a top plate (11), a ring (4) for the outside diameter of an annular preform being treated within the constraint fixture, and a ring (10) for the inside diameter of the annular preform. The outside diameter and inside diameter rings are made of thin flexible sheet metal strips or thin flexible carbon-carbon composite strip material. The thin flexible strips are joined together by deformable joints, so that the flexible constraint system retains pitch within the fibrous matrix of the preform. The outside diameter strips may be joined together by expandable joints and the inside diameter strips may be joined together by collapsible joints. Also, a method of avoiding damage to an annular fibrous preform, e.g., an aircraft brake disc preform, during a carbonization procedure. This method involves carbonizing the annular fibrous preform in the constraint fixture of the invention.
