Abstract

The present invention discloses a composite heating material plate for aviation technology, comprising an outer carbon plate. Two carbon plates are provided. An outer insulating layer is fixedly connected to one side opposite to the two outer carbon plates. A filling layer is fixedly connected to one side of the outer insulating layer. A conductive gasket is fixedly connected to the side of the filling layer away from the outer insulating layer. A limiting rod is fixedly connected to the conductive gasket. An inner insulating layer is provided between two adjacent limiting rods. A heating block is provided between the inner insulating layer and the conductive gasket, so that heating can be achieved. Meanwhile, heat conduction can be facilitated by the conductive gasket. Power supply enables the heating block to heat. Since the heating blocks are evenly distributed on the inner insulating layer and through the first through hole provided on the filling layer, the heating energy is distributed in a point shape on the surface of the outer carbon plate, so that the problem of icing easily encountered when the material plate is used in the high altitude can be solved. Meanwhile, by providing a support block and a connector in the inner carbon plate, the inner and outer carbon plates are both made of carbon fiber, which greatly reduces the weight and improves the control accuracy.

[0027] The inner insulating layer 6 and the outer insulating layer 2 are both made of a composite of polyimide and nylon.
