METHOD FOR MANUFACTURING MULTIPLE SEAL ARC SEGMENTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18296633 titled 'METHOD FOR MANUFACTURING MULTIPLE SEAL ARC SEGMENTS

The method described in the patent application involves creating a fiber preform with a repeating pattern of seal arc sections using ceramic tows, densifying the preform with a ceramic matrix material to form a densified ceramic matrix composite body, and then cutting the preform or the composite body along boundaries between the seal arc sections to separate the seal arc segments.

• The innovation involves the use of ceramic tows to create a fiber preform with seal arc sections.
• Densifying the preform with a ceramic matrix material results in a densified ceramic matrix composite body.
• Cutting along boundaries between the seal arc sections allows for the separation of seal arc segments.

Original Abstract Submitted

A method includes laying-up a fabric made of ceramic tows to form a fiber preform that has a repeating pattern of seal arc sections, densifying the fiber preform with a ceramic matrix material to form a densified ceramic matrix composite body, and then either before or after the densifying, cutting the fiber preform or the densified ceramic matrix composite body, respectively, along boundaries between the seal arc sections to separate the seal arc segments from each other.
