Electric heating technology is critical for aerospace de‐icing systems due to its efficiency and controllability. However, traditional electric elements such as resistance wires metal coatings have low thermal conductivity, poor high‐temperature resistance, insufficient structural flexibility, which severely limit their application in composites. This study introduces carbon nanotube (CNT)/nanocellulose fiber (CNF) composite films a solution. CNTs, with exceptional stability, mechanical strength, enhance efficiency. Through the patterned design, further optimized, heat distribution during process made more uniform. Experimental results show that when mass ratio of CNTs CNFs 10:1, conductivity material reaches 2.68 W/(m·K), it exhibits significant Joule effect. When power density 0.4 W cm −1 2 , CNTs/CNFs (10:1) film can rapidly reach 140.6 °C after 10 s heating. Additionally, use fiber‐reinforced composites improves durability system, allowing system operate stably under high‐frequency cycles, significantly enhancing reliability service life. high capability allows rapid local temperature elevation, reducing energy consumption boosting
