在这里，我们报告的发展和评价的混合多尺度环氧树脂复合材料制成的传统的碳纤维织物与层间区域含有垫的静电纺碳纳米纤维（ECNs）。结果表明：（1）混杂多尺度复合材料的层间剪切强度和弯曲性能明显高于不含ECN的对照/对比复合材料，尤其是层间剪切强度提高了约86%;和（2）通过掺入ECN，在面内和面外方向上的电导率都得到增强，而面外电导率的增强（类似于150%）远大于面内电导率的增强（类似于20%）。为了验证数据处理方法的有效性，提出了一个新的复合材料层合板剪应力计算公式，该公式考虑了铺层和夹层的影响。该研究表明，ECN可用于开发高性能复合材料，特别是具有改进的计划外性能（例如，层间剪切强度）。(C)2011爱思唯尔有限公司保留所有权利。
Herein we report the development and evaluation of hybrid multi-scale epoxy composite made of conventional carbon fiber fabrics with interlaminar regions containing mats of electrospun carbon nanofibers (ECNs). The results indicated that (1) the interlaminar shear strength and flexural properties of hybrid multi-scale composite were substantially higher than those of control/comparison composite without ECNs; in particular, the interlaminar shear strength was higher by similar to 86%; and (2) the electrical conductivities in both in-plane and out-of-plane directions were enhanced through incorporation of ECNs, while the enhancement of out-of-plane conductivity (similar to 150%) was much larger than that of in-plane conductivity (similar to 20%). To validate the data reduction procedure, a new shear stress formula was formulated for composite laminates, which took into account the effect of layup and inter-layers. The study suggested that ECNs could be utilized for the development of high-performance composites, particularly with the improved out-of-plan properties (e.g., interlaminar shear strength).
