Abstract
A ceramic matrix composite part and methods of locating a composite ply on a layup tool are presented. A composite ply comprising a fiducial is placed onto the layup tool. A position of the fiducial of the composite ply is determined relative to the layup tool. An actual position of the composite ply on the layup tool is determined. A difference between the actual position of the composite ply and a designed position for the composite ply is determined.
Claims26
A method of locating a composite ply on a layup tool comprising:
- placing a composite ply comprising a fiducial onto the layup tool;
- determining a position of the fiducial of the composite ply relative to the layup tool;
- determining an actual position of the composite ply on the layup tool;
- and
- determining a difference between the actual position of the composite ply and a designed position for the composite ply.
A method of locating a composite ply on a layup tool comprising:
- cutting a ply shape into a sheet of ceramic matrix composite material having a plurality of fiducials printed on a surface of the ceramic matrix composite material to form a composite ply comprising a fiducial of the plurality of fiducials;
- placing the composite ply comprising the fiducial onto the layup tool;
- and
- determining a position of the composite ply on the layup tool based on a position of the fiducial relative to the layup tool.
A method of locating a composite ply on a layup tool comprising:
- cutting a ply shape into a sheet of ceramic matrix composite material having a protective film;
- placing a fiducial onto the protective film within the ply shape to form a composite ply comprising the fiducial;
- placing the composite ply comprising the fiducial onto the layup tool;
- and
- determining a position of the composite ply on the layup tool based on a position of the fiducial relative to the layup tool.
(canceled)
A ceramic matrix composite part comprising:
- a plurality of ceramic matrix composite plies;
- and
- ink between two plies of the plurality of ceramic matrix composite plies.
