A thermoelectric heater mat 10 comprising an electrically resistive heater element 22 embedded in a thermoplastic layer 16 suitable for use as an aircraft leading edge ice protection system. The heater element 22 may be a sprayed metal layer and the thermoplastic layer 16 may be polyetheretherketone. There may be metallic terminal leads 14 connected to the heater element 22 and these may be partially embedded in the thermoplastic 16. The heater element 22 may be located in between two stabilising layers 21, which may be a glass. The heater mat 10 may have a double-curved shape to conform with the curved surface of an aircraft leading edge, which may be a wing. The heater mat 10 may be formed by applying the heater element 22 to a layer of thermoplastic material 28, adding a second layer of thermoplastic material 26 over the heater element 22, then heating the thermoplastic material, possibly to 360-380{C, to fuse the thermoplastic layers 26,28 to the heater element 22. The heater mat 10 may then be quenched, and the heating may be performed in a vacuum. |
