将碳纳米管有效地掺入低粘度聚酯/乙烯基酯树脂中，然后通过高压注射法将其用于玻璃纤维织物的浸渍，得到碳纳米管/玻璃纤维/聚合物多尺度复合材料。通过测量所制备的复合材料的局部密度来检查纳米管在复合材料中的分布。局部密度的均匀性和扫描电子显微镜表征验证了所制备的复合材料的均匀形态。理论计算和实验表征均表明，复合材料的导热性能得到了显著提高。掺入3wt%的碳纳米管导致热导率提高了1.5倍。这些结果将进一步扩大纤维复合材料的工业应用。
Carbon nanotubes were effectively incorporated into low-viscosity polyester/vinyl ester resins and then used for infusion of glass fiber textiles by high-pressure injection, resulting in carbon nanotubes/glass fiber/polymer multiscale composites. The nanotubes distribution in the composites was examined by measuring the local density of as-produced composites. The uniformity of local density and scanning electron microscope characterization verified the homogeneous morphology of as-produced composites. Both theoretical calculation and experimental characterization indicated thermal conductivity was significantly improved. Incorporation of 3wt% carbon nanotubes has resulted in 1.5-folds enhancement of thermal conductivity. These results will further increase industrial application of the fiber composites.
