柔性基板在从电子到生物医学设备的应用中实现了新的功能。为了为这些应用提供一个新的平台，我们研究了一种由硬质纤维织物浸透软弹性体组成的复合材料，这种复合材料能够制造出承载能力强的柔性基板。我们演示了一种集成和简便的一步压印平版印刷方法，可用于多种织物和树脂。此外，研究了复合材料的弯曲和拉伸性能，并将其与其他柔性材料（如PET和纤维素纸）进行了比较。碳纤维复合材料具有比PET更高的拉伸模量，同时保持几乎低一个数量级的弯曲模量。织物复合材料还具有均质材料所没有的各向异性力学性能。最后，我们讨论了这些各向异性力学响应及其在柔性应用中的潜在应用。
Flexible substrates enable new capabilities in applications ranging from electronics to biomedical devices. To provide a new platform for these applications, we investigate a composite material consisting of rigid fiber fabrics impregnated with soft elastomers, offering the ability to create load bearing, yet flexible substrates. We demonstrate an integrated and facile one-step imprint lithographic patterning method on a number of fabrics and resins. Furthermore, the bending and tensile properties were examined to compare the composites to other flexible materials such as PET and cellulose paper. Carbon fiber composites possess a higher tensile modulus than PET while retaining almost an order of magnitude lower bending modulus. Fabric composites can also have anisotropic mechanical properties not observed in homogeneous materials. Finally, we provide a discussion of these anisotropic mechanical responses and their potential use in flexible applications.
