Most natural and man-made fibers have circular cross-sections; thus the properties of materials composed of non-circular fibers are largely unexplored. We demonstrate the technology for fabricating fibers with predetermined cross-sectional shape. Passive hydrodynamic focusing and UV polymerization of a shaped acrylate stream produced metre-long fibers for structural and mechanical characterization.
大多数天然纤维和人造纤维都具有圆形横截面；因此，由非圆形纤维组成的材料的性能在很大程度上尚未得到探索。我们展示了制造具有预定横截面形状的纤维的技术。通过被动流体动力学聚焦和形状丙烯酸盐流的 UV 聚合，制造出了用于结构和机械特性分析的米长纤维。
