摘　　要：为了开发低成本、低能耗和高效率非热压罐复合材料固化成型技术,利用浮动催化化学气相沉积法制备了碳纳米管薄膜,并将其用于玻璃纤维增强树脂基复合材料的电加热固化,对碳纳米管薄膜进行结构和电热性能分析。结果表明,薄膜为微观多孔性材料,且具有优异的电热性能和稳定性。与传统烘箱加热固化方式相比,碳纳米管薄膜电加热固化技术可将能耗和成型时间分别降低83.7%和28.9%,较为节能高效。力学性能测试表明,该技术制备的复合材料具有与烘箱固化复合材料相似的固化度和拉伸力学性能。To develop an out-of-autoclave composite curing technology with lower cost, less energy-consumption and high effi- ciency, carbon nanotube （CNT） film fabricated by floating catalyst chemical vapor deposition method was adopted as the resistive heater to cure the glass fiber reinforced composite by its Joule heating. It was found that CNT film was of high porosity and possessed fast heating rate and super thermal stability. Compared to the conventional oven curing method, the energy consumption and process- ing cycle of this newly developed curing method were decreased by about 83.7% and 28.9%, respectively. In addition, the cure de- gree and mechanical property of the composites cured by CNT Joule heating were found similar to those of the composites cured by conventional oven method.
