A method of making a flexible and rugged laminar heater (1) in which a nonwoven cloth layer (6) serves to reduce air void formation during lamination. The heater (1) of the invention comprises a laminar conductive polymer heating element (2), at least two electrodes (3), at least one polymeric insulating layer (7), and at least one nonwoven cloth layer (6). Suitable nonwoven cloths may comprise nylon or glass. In addition to eliminating air voids, they are useful in minimizing distortion of the laminate. |
