A method for forming a fire shield for an aircraft engine, the method comprising:
- forming a case template matching a case body of the fire shield, and the case template has a first template side and a second template side;
- forming a fire shield layer at the second template side by spraying a fire shield material at the second template side;
- and
- attaching the fire shield layer to the case body.
A method for forming a fire shield for an aircraft engine, the method comprising:
- applying a release film onto a case template;
- forming a fire shield layer on the case template by applying a fire shield material onto the release film;
- cutting the case template, the release film, and the fire shield layer into a plurality of pieces, and each piece of the plurality of pieces includes a portion of the case template, a portion of the release film, and a portion of the fire shield layer;
- removing the portion of the fire shield layer from the portion of the release film for each piece of the plurality of pieces;
- and
- attaching each portion of the fire shield layer onto a case body of the fire shield.
A method for forming a fire shield for an aircraft engine, the method comprising:
- forming a polymer-material case template matching a metallic case body of the fire shield;
- forming a fire shield layer on the polymer-material case template by spraying a fire shield material directly onto the polymer-material case template;
- and
- attaching the polymer-material case template to the metallic case body with the polymer-material case template disposed between the metallic case body and the fire shield layer.
