摘要
The heating element, intended in particular for the heating of large heating areas, has an inner, electrically conducting layer (2), containing electrodes (3), and outer, electrically non-conducting layers (1). To achieve a greater stability of the characteristic electrical values and a high mechanical strength of the heating element, the electrodes (3) are arranged in the electrically conducting layer (2), which consists at least of a polyester resin composition containing at most 10% by weight of carbon black, referred to the amount of polyester resin, in the form of a metal network or carbon-fibre network or of a perforated metal foil in the same form as the heating element. The electrically conducting layer (2) and the insulating layers (1) are reinforced with glass fibres (4). IMAGE
