For glass fiber/epoxy composite materials， the pre-encapsulated graphene heating element is embedded in the interlayer of composite material by using the hot-pressing preparation process of flat plate vulcanizer， so as to prepare the composite heating component. Experiments show that the preparation method has little effect on the resistance and heating performance of graphene materials， thus ensuring the anti-icing/de-icing efficiency of graphene heating elements. Then， based on the composite heating components， thermal/mechanical experiments and de-icing performance experiments are carried out. The test results show that the temperature growth rate of composite heating components increases with the increase of heat flux， and the position of layer has a great influence on the temperature rise of composite heating components. In the cold environment de-icing experiment， when the ambient temperature is -20 ℃ and the heat flow density is 0.3 W/cm²， compared with the traditional electric heating component， the de-icing time of the composite heating component is greatly reduced， and the energy consumption is reduced by about 30%， which lays a foundation for the further preparation of the composite heating wing.
