An anti-icing and de-icing method for a composite material component is characterized by comprising the following steps: firstly, dividing an area needing to be de-iced into a plurality of equal-area heating areas; secondly, a heating unit formed by bending an electric heating wire is manufactured for each heating area; thirdly, a plurality of heating units are connected in parallel to form heating sets, all the heating sets are connected to form a heating device, the heating device is arranged on the first resin film, and then the first resin film and the heating device are arranged on the area, needing to be deiced, of the composite material component together; and finally, covering a second resin film on the heating device and sealing the second resin film with the first resin film, switching on the power supply, and controlling the voltage of the power supply to reach the heating power. According to the invention, the damage resistance of the electrothermal film can be improved while the single independent heating area reaches the required heating power, and in addition, the electric heating wire structures of other areas can be determined through the electric heating wire structures of the independent heating areas.
一种复合材料构件防除冰方法,其特征是:首先,将需要除冰的区域划分成若干等面积加热区;其次,为每个加热区制作一个由电加热丝弯折形成的加热单元;第三,将若干加热单元并联形成加热组,将所有加热组相连形成加热装置,将加热装置置于第一树脂薄膜上,再将第一树脂薄膜与加热装置一并置于复合材料构件需要除冰的区域上,最后在加热装置上覆上第二树脂薄膜并使其与第一树脂薄膜贴合密封,接通电源,控制电源电压达到加热功率。本发明能够在保证单个独立加热区域达到所需加热功率的同时提高电热薄膜的抗破坏性能,此外还能够通过独立加热区域电加热丝结构确定其他区域电加热丝结构。
