Abstract

A method of remanufacturing a liner panel for a gas turbine engine includes removing a bushing from a damaged component; and molding the bushing with a material charge. A liner panel for a gas turbine engine includes a forward fan exit case liner panel with a donor bushing from a damaged forward fan exit case liner panel. A liner panel for a gas turbine engine includes a forward fan exit case liner panel molded from a material charge that includes a multiple of layers. At least one of the multiple of layer includes a discontinuity.

Claims (17)

1. A method of remanufacturing a liner panel for a gas turbine engine, comprising:

removing a bushing from a damaged component; and

molding the bushing with a material charge;

wherein the material charge includes a multiple of layers, and at least one of the multiple of layers incudes a discontinuity; and

wherein a main body of one of the multiple of layers defines a width (WM) and the discontinuity of one of the multiple of layers defines a width (WD), and wherein a ratio WD/WM is defined between 0.575-0.66.

2. The method as recited in claim 1 , wherein the width WM of the main body is exclusive of a multiple of tabs.

3. A liner panel for a gas turbine engine, comprising:

a forward fan exit case liner panel with a donor bushing from a damaged forward fan exit case liner panel;

wherein the forward fan exit case liner panel is molded from a material charge that includes a multiple of layers, and at least one of the multiple of layers includes a discontinuity; and

wherein a main body of one of the multiple of layers defines a width (WM) and the discontinuity of one of the multiple of layers defines a width (WD), a ratio WD/WM is defined between 0.575-0.66, and the width WM of the main body is exclusive of a multiple of tabs.

4. The liner panel as recited in claim 3 , wherein the forward fan exit case liner panel includes a multiple of bushings, and the donor bushing is metallic.

5. The liner panel as recited in claim 4 , wherein at least one of the multiple of bushings is non-metallic.

6. The liner panel as recited in claim 3 , wherein the multiple of layers are each carbon fiber based.

7. A liner panel for a gas turbine engine, comprising:

a forward fan exit case liner panel molded from a material charge that includes a multiple of layers, wherein at least one of the multiple of layer includes a discontinuity; and

wherein a main body of one of the multiple of layers defines a width (WM) and the discontinuity of one of the multiple of layers defines a width (WD), a ratio WD/WM is defined between 0.575-0.66, and the width WM of the main body is exclusive of a multiple of tabs.

8. The liner panel as recited in claim 7 , wherein the material charge is carbon fiber based.
