    摘要:

    对新型化学气相沉积法(CVD法)制备的碳纳米管薄膜(CNTF)的相结构和微观形貌进行了表征。根据CNTF内的碳纳米管杂乱交错,排列无规则,但孔隙率较高的微观结构特点,提出了基于这种CNTF的飞机电热防除冰系统的设计方案及其制备工艺流程。该方案采用了CNTF和环氧树脂等轻质材料,对样件制备工艺进行了探讨和优化。通过电发热特性测试及防除冰功能测试对此种新型电热防除冰系统样件的电热性能进行了研究。试验结果表明,此种新型电热防除冰系统结构简单,质量小,易于与飞机铝合金蒙皮相结合,有利于减小飞机空重,降低飞行成本;在电热过程中获得的有效平均温度为47℃,可有效地加快冰层融化,在实际应用中具有良好的前景。

    Abstract:

    Phase structure and micro-morphology of carbon nanotube film (CNTF) prepared with the chemical vapor deposition (CVD) method were characterized. According to the micro-structure characteristics of carbon nanotubes in CNTF, which are disordered and arranged irregularly, but have high porosity, the design scheme and preparation process of aircraft electro-thermal anti-icing system based on CNTF are proposed. In this program, light materials such as CNTF and epoxy resin were used, and the sample preparation process was discussed and optimized. The electro-thermal performance of this new type of electro-thermal anti-icing system''s sample was studied through the test of electro-thermal heating characteristics and anti-icing function tests. The results show that this new type of electro-thermal anti-icing system has simple structure and light weight, and is easy to be combined with aircraft aluminum alloy skin, which is conducive to reducing aircraft empty weight and flight cost. The effective average temperature obtained in the electric heating process is 47℃, which can effectively accelerate the melting of ice layer and has a good prospect in practical application.
