纤维增强复合材料在先进工程材料方面提供了巨大的机遇，但纤维的产生和空间分布是最具挑战性的方面。本文提出了一种浸渍和近场电纺相结合的纤维增强复合材料的制备方法。新的浸没式电液动力直写(I-EHD)工艺利用静电力拉伸超细纤维，并允许电纺纤维全部独立于液体基质中。这种新方法能够动态控制纤维形态和复合材料内部的三维空间分布，这可能导致未来多功能复合材料的可伸缩3D打印。
Fiber-reinforced composites have provided tremendous opportunities in advanced engineering materials, but the fiber generation and spatial distribution are the most challenging aspects. This paper proposes a novel fabrication approach for fiber-reinforced composites with spatially resolved fiber distribution by combining immersion and near-field electrospinning. The new Immersed Electrohydrodynamic Direct-writing (I-EHD) process makes use of an electrostatic force to draw ultrafine fibers and allows the freestanding of electrospun fibers all inside a liquid matrix. This novel approach enables the dynamic control of fiber morphology and 3D spatial distribution inside the composites, which may lead to future scalable 3D printing of multifunctional composites.
