Abstract
A heated floor panel assembly for aircraft includes structural layers made of a fiber matrix and a high temperature thermoplastic resin. The structural layers are within the heated floor panel assembly to protect the other assembly components from damage and absorb stress. The heated floor panel assembly further includes a heating layer with a heating element, an impact layer, and a core layer to take shear stress exerted on the assembly.
Claims18
A floor panel assembly having a bottom surface and a top surface, the floor panel assembly comprising:
- a first stack of structural layers disposed adjacent the bottom surface, wherein the first stack of structural layers includes a first plurality of structural layers bonded together, and wherein each layer of the first plurality of structural layers comprises:
- a first fiber matrix;
- and
- a first high temperature thermoplastic resin infiltrating the first fiber matrix;
- a core layer, adjacent the first stack of structural layers, that absorbs shear stress;
- a heating layer between the core layer and the top surface and adjacent the core layer;
- a second stack of structural layers disposed between the heating layer and the top surface and adjacent the heating layer, wherein the second stack of structural layers includes a second plurality of structural layers bonded together, and wherein each layer of the second plurality of structural layers comprises:
- a second fiber matrix;
- and
- a second high temperature thermoplastic resin infiltrating the second fiber matrix;
- and
- an impact layer between the heating layer and the top surface and between the second stack of structural layers and the top surface, wherein the first stack of structural layers, the core layer, the heating layer, the second stack of structural layers, and the impact layer are bonded together.
A method of making a floor panel assembly having a bottom surface and a top surface and comprising:
- aligning a first plurality of structural layers comprising two or more high temperature thermoplastic pre-impregnated fiber matrices adjacent the bottom surface, a core layer adjacent the first plurality of structural layers, a heating layer between the core layer and the top surface and adjacent the core layer, a second plurality of structural layers comprising two or more high temperature thermoplastic pre-impregnated fiber matrices between the heating layer and the top surface, and an impact layer between the heating layer and the top surface and between the second plurality of structural layers and the top surface;
- bonding the first plurality of structural layers, core layer, heating layer, second plurality of structural layers, and impact layer together.
