Abstract Next-generation composite manufacturing processes are needed to overcome several limitations of conventional manufacturing processes (e.g., high energy consumption). Here we explore, via experiments and modeling, the characteristics of the newly developed out-of-oven (OoO) curing technique that cures a composite laminate via resistive heating of a carbon nanotube film. When compared to oven curing of an aerospace-grade out-of-autoclave (OoA) carbon fiber prepreg advanced composite laminate, the OoO curing reduces energy consumption by over two orders of magnitude (14 vs. 0.1 MJ). Thermophysical and mechanical tests including differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), short beam shear (SBS), and ex-situ and in-situ double-edge notch tension (DENT) indicate that the physical and mechanical properties of OoO-cured laminates are equivalent to those of oven-cured (baseline) laminates. In addition to energy savings, the OoO curing process has the potential to reduce part-to-part variations through improved spatiotemporal temperature control.

通过纳米结构的炉外导电固化制造先进的碳纤维复合材料非高压釜层压板

摘要 需要下一代复合材料制造工艺来克服传统制造工艺的若干限制（例如，高能耗）。在这里，我们通过实验和建模探索了新开发的炉外 (OoO) 固化技术的特性，该技术通过碳纳米管薄膜的电阻加热来固化复合层压板。与航空级高压釜外 (OoA) 碳纤维预浸料高级复合层压板的烤箱固化相比，OoO 固化将能耗降低了两个数量级以上（14 与 0.1 MJ）。热物理和机械测试，包括差示扫描量热法 (DSC)、动态力学分析 (DMA)、短束剪切 (SBS)、异位和原位双边缘缺口张力 (DENT) 表明 OoO 固化层压板的物理和机械性能与烘箱固化（基线）层压板的物理和机械性能相当。除了节能之外，OoO 固化工艺还有可能通过改进时空温度控制来减少部件之间的差异。
